The main +use case is to get remote access to virtual machines, although other +use cases are possible and in various development stage. + +Spice provides a desktop-like user experience, while trying to offload +most of the intensive CPU and GPU tasks to the client. The basic +building blocks of Spice are: + + * <<spice-server, Spice Server>> + * <<spice-client, Spice Client>> + * <<spice-protocol, Spice Protocol>> + +The following sections provide basic information on Spice components +and features, obtaining, building installing and using Spice. + +Spice and Spice-related components +---------------------------------- + +[[spice-server]] +Spice Server +~~~~~~~~~~~~ + +Spice server is implemented in libspice, a VDI pluggable +library. Currently, the main user of this library is QEMU. QEMU uses +spice-server to provide remote access to virtual machines through the +Spice protocol. Virtual Device Interface (VDI) defines a set of +interfaces that provide a standard way to publish virtual devices +(e.g. display device, keyboard, mouse) and enables different Spice +components to interact with those devices. On one side, the server +communicates with the remote client using the Spice protocol and on +the other side, it interacts with the VDI host application (e.g QEMU). + +[[spice-client]] +Spice Client +~~~~~~~~~~~~ + +The Spice client is a program which is used by the end user to access +remote systems through Spice. The recommended client is remote-viewer +(which is shipped with virt-viewer). GNOME Boxes can also be used as a +Spice client. spicec is an obsolete legacy client, and spicy is only a +test application. + +QXL Device and Drivers +~~~~~~~~~~~~~~~~~~~~~~ + +Spice server supports the QXL VDI interface. When libspice is used +with QEMU, a specific video PCI device can be used for improving +remote display performance and enhancing the graphic capabilities of +the guest graphic system. This video device is called a QXL device and +requires guest QXL drivers for full functionality. However, standard +VGA is supported when no driver exists. + +Spice Agent +~~~~~~~~~~~ + +The Spice agent is an optional component for enhancing user experience +and performing guest-oriented management tasks. For example, the agent +injects mouse position and state to the guest when using client mouse +mode. It also enables you to move cursor freely between guest and +client. Other features of agent are shared clipboard (copy and paste +between guest and host) and aligning guest resolution with client when +entering fullscreen mode. + +VDI Port Device +~~~~~~~~~~~~~~~ + +The Spice protocol supports a communication channel between the client +and the agent on the server side. When using QEMU, Spice agent resides +on the guest. VDI port is a QEMU PCI device used for communication +with the agent. + +[[spice-protocol]] +Spice Protocol +~~~~~~~~~~~~~~ + +The Spice protocol defines the messages and rules for the +communication between the various Spice components. + +Features +-------- + +Multiple Channels +~~~~~~~~~~~~~~~~~ + +The server and client communicate via channels. Each channel is +dedicated to a specific type of data. The available channels are the +following: + +Main:: +control and configuration + +Display:: +graphics commands images and video streams + +Inputs:: +keyboard and mouse inputs + +Cursor:: +pointer device position and cursor shape + +Playback:: +audio received from the server to be played by the client + +Record:: +audio captured on the client side + +Smartcard:: +passthrough of smartcard data from the client machine to the guest OS + +USB:: +redirection of USB devices plugged into the client to the guest OS + +Image Compression +~~~~~~~~~~~~~~~~~ + +Spice offers several image compression algorithms, which can be chosen +on server initiation and dynamically at run-time. Quic is a Spice +proprietary image compression technology based on the SFALIC +algorithm. The Lempel-Ziv (LZ) algorithm is another option. Both Quic +and LZ are local algorithms encoding each image separately. Global LZ +(GLZ) is another proprietary Spice technology that uses LZ with +history-based global dictionary. GLZ takes advantage of repeating +patterns among images to shrink the traffic and save bandwidth, which +is critical in a WAN environment. Spice also offers an automatic mode +for compression selection per image, where the choice between LZ/GLZ +and Quic is heuristically based on image properties. Conceptually, +synthetic images are better compressed with LZ/GLZ and real images are +better with Quic. + +Video Compression +~~~~~~~~~~~~~~~~~ + +Spice uses loss-less compression for images sent to the +client. However, video streams are handled differently. Spice server +heuristically identifies video areas and sends them as a video stream +coded using M-JPEG. This handling saves a lot of traffic, improving +Spice performance, especially in a WAN environment. However, in some +circumstances the heuristic behavior might cause low quality images +(e.g. identifying updated text area as a video stream). Video +streaming can be chosen on server initiation and dynamically at +run-time. + +Mouse modes +~~~~~~~~~~~ + +Spice supports two mouse modes: server and client. The mode can be +changed dynamically and is negotiated between the client and the +server. + +Server mouse:: +When a user clicks inside the Spice client window, the client mouse is +captured and set invisible. In this mode, the server controls the +mouse position on display. However, it might be problematic on WAN or +on a loaded server, where mouse cursor might have some latency or +non-responsiveness. + +Client mouse:: +Not captured and is used as the effective pointing device. To enable +client mouse, the VDI host application must register an absolute +pointing device (e.g. USB tablet in QEMU). This mode is appropriate +for WAN or or for a loaded server, since cursor has smooth motion and +responsiveness. However, the cursor might lose synchronization +(position and shape) for a while. + +Other Features +~~~~~~~~~~~~~~ + +Multiple Monitors:: +any number of monitors is supported + +Arbitrary Resolution:: +when using the QXL driver, the resolution of the guest OS will be +automatically adjusted to the size of the client window. + +USB Redirection:: +Spice can be used to redirect USB devices that are plugged in the +client to the guest OS. This redirection can either be automatic (all +newly plugged devices are redirected), or manual (the user selects +which devices (s)he wants to redirect). + +Smartcard Redirection:: +data from smartcard that are inserted into the client machine can be +passed through to the guest OS. The smartcard can be used by both the +client OS and the guest OS. + +Bidirectional Audio:: +Spice supports audio playback and recording. Playback is compressed +using the CELT algorithm + +Lip-sync:: +between video and audio. Available only when video streaming is +enabled. + +Migration:: +switching channel connectivity for supporting server migration + +Pixmap and Palette caching:: +image data is cached on the client to avoid sending the same data + +Using Spice +=========== + +[NOTE] +I'll use `qemu-kvm` as a name for the executable. If you're using a +manually built qemu or a qemu without kvm then just replace `qemu-kvm` +with your own binary. I'll use `host$`, `client$` and `guest$` shell +prompt notations to distinguish where the command should be the +command. See section <<glossary>> to be sure that you know +difference between the host, client and guest. You can ignore the +difference between guest, client and host if they are all running on +the same machine. + +Running qemu manually +--------------------- + +*The first thing to do* is to create a guest image. You can use any +raw device such as a clean logical volume, or an iSCSI lun. You may +also use a file as the disk image for the guest. I'll use a file +created by `qemu-img` as a demonstration. + +The following command will allocate a 10GB file. See `qemu-img` man +page for further information. + +[source,sh] +host$ qemu-img create /path/to/xp.img 10G + +Now that we created an image, we can now start with image +population. I assume that you have a locally stored ISO of your +favourite operating system so you can use it for installation. + +[source,sh] +host$ sudo qemu-kvm -boot order=dc -vga qxl \ + -spice port=3001,disable-ticketing -soundhw ac97 \ + -device virtio-serial -chardev spicevmc,id=vdagent,debug=0,name=vdagent \ + -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \ + -cdrom /path/to/your.iso /path/to/your.img + + +Let's take a brief look at the qemu options that were used. The option +`-boot order=dc` specifies that the guest system should try to boot +from the first cdrom and then fallback to the first disk, `-vga qxl` +specifies that qemu uses a qxl graphics device. + +The Spice `port` option defines what port will be used for +communication with the client. The Spice option `disable-ticketing` is +specifying that ticketing (simple authentication method) is not +used. The virtio and chardev devices are required by the guest agent. + +Basic configuration +------------------- + +This section will assume that you already have a running QEMU virtual +machine, and that you are running it either through virt-manager, +libvirt or through direct QEMU use, and that you want to enable Spice +support for this virtual machine. + +.Using virt-manager + +Double-click on the virtual machine you are interested in, go to +"View/Details". If the left pane has a "Display Spice" entry, then the +virtual machine already has Spice support, and you can check the +connection details (port number) by clicking on it. If it has no Spice +entry, click on "Add Hardware", and add a "Graphics" element of type +"Spice server". If the host and the client are not the same machine, +you should check the "Listen on all public network interfaces" +checkbox, otherwise you don't need to make any changes. + +You should also add a QXL video device. It can be done by +double-clicking on a virtual machine, then by going to View/Details, +and by clicking on "Add Hardware" if the virtual machine does not have +a "Video QXL" item in its left pane. From the "Add hardware" dialog, +you should then create a "Video" device whose model is "QXL". + +After stopping and restarting the virtual machine, it should be +accessible with a Spice client. + +You can remove non-Spice display entries and non-QXL video entries +from the virtual machine configuration. + +If you go to "Edit/Preferences/VM Details" in the main virt-manager +window, you can set Spice graphics type as the default setting for new +virtual machines. + +.Using libvirt + +All libvirt examples will assume that the virtual machine to modify is +`$vmname` and that virsh is using the correct libvirt connection by +default. + +To add Spice support to an existing virtual machine managed by +libvirt, you need to edit it: + +[source,sh] +host$ virsh edit $vmname + +and then add a Spice graphics element: + +[source,xml] +<graphics type='spice'/> + +You should also add a QXL video device + +[source,xml] +<video> + <model type='qxl'> +</video> + +After stopping and restarting the virtual machine `$vmname`, it should +be accessible through Spice. You can check the connection parameters +with: + +[source,sh] +host$ virsh domdisplay $vmname + +.Using QEMU + +To enable Spice support to your virtual machine, you only need to +append the following to your QEMU command line: + +[source,sh] +-spice port=3001,disable-ticketing + +This will setup a Spice session listening on port 3001 exporting your +virtual machine display. + +You can also add a QXL device by appending `-vga qxl` to the command +line. + +Connecting to the guest +----------------------- + +The following section will show you basic usage of the Spice +client. The example connection will be related to the qemu instance +started in the previous sections. + +Be aware that the port used for spice communication (port 3001 in our +case) should not be blocked by firewall. Host `myhost` is referring to +the machine which is running our qemu instance. + +[source,sh] +client$ remote-viewer spice://myhost:3001 + +.Established connection to Windows 2008 guest +image::images/spicec01.png[] + + +Ticketing +========= + +Spice does not support multiple connections to the same QEMU instance +by default. So anybody who will connect to the same host and port can +simply take over your session. You can solve this problem by using +ticketing. + +Ticketing is a simple authentication system which enables you to set +simple tickets to a VM. Client has to authenticate before the +connection can be established. See the Spice option `password` in the +following examples. + +Configuration +------------- + +.Using virt-manager + +To set a Spice password for a virtual machine, go to this machine +details in virt-manager, and then click on the "Display Spice" item in +the left pane, and enter the ticket you want to use in the "Password" +field. + +.Using libvirt + +All you need to do is to append a `passwd` attribute to the Spice +graphics node for your virtual machine: + +[source,xml] +<graphics type='spice' passwd='mysecretpassword'/> + +.Using QEMU + +Adding a ticket with QEMU involves a slight modification of the +`-spice` parameter used when running QEMU: + +[source,sh] +-spice port=3001,password=mysecretpassword + +Client +------ + +When you start the client as usual, if ticketing was enabled on the +host, remote-viewer will pop up a window asking for a password before +starting the Spice session. It won't be established if an incorrect +ticket was passed to the client. + +IMPORTANT: You might have figured out that passing tickets as a +command-line option isn't very safe. It's not safe as everybody with +access to the host can read it from the output of `ps(1)`. To prevent +this, the ticket can be also set by using the QEMU console command +`spice._set_ticket`. + + +[[agent]] +Agent +===== + +Agent support allows better integration with the guest. For example, +it allows copy and paste between the guest and the host OSes, dynamic +resolution changes when the client window is resized/full-screened, +file transfers through drag and drop, ... + +The agent is a daemon/service running in the guest OS so it must be +installed if it was not installed by default during the guest OS +installation. It also relies on a virtio-serial PCI device and a +dedicated spicevmc char device to achieve communication between the +guest and the host. These devices must be added to the virtual machine +for the agent to work in the guest. + +Configuration +------------- + +.Using virt-manager + +The needed devices can be added from the virtual machine +details. Click on "Add hardware" and then add a "Channel" device with +type "Spice agent (spicevmc)". This will automatically add the needed +virtio-serial device in addition to the spicevmc channel. + +.Using libvirt + +Two distinct devices must be added: + +* http://libvirt.org/formatdomain.html#elementsControllers[a virtio serial device] +* http://libvirt.org/formatdomain.html#elementCharChannel[a spicevmc channel] + +[source,xml] +<devices> + <controller type='virtio-serial' index='0'/> + <channel type='spicevmc'> + <target type='virtio' name='com.redhat.spice.0'/> + </channel> +</devices> + +.Using QEMU + +Adding the following parameters to your QEMU command line will enable +the needed devices for agent support in the guest OS: + +[source,sh] +-device virtio-serial \ +-chardev spicevmc,id=vdagent,debug=0,name=vdagent \ +-device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \ + +USB redirection +=============== + +With USB redirection, USB devices plugged into the client machine can +be transparently redirected to the guest OS. This redirection can +either be automatic (all newly plugged devices are redirected), or +manual (the user selects which devices (s)he wants to redirect). + +For redirection to work, the virtual machine must have an USB2 EHCI +controller (this implies 3 additional UHCI controllers). It also needs +to have Spice channels for USB redirection. The number of such +channels correspond to the number of USB devices that it will be +possible to redirect at the same time. + +Configuration +------------- + +.Using virt-manager + +Virtual machines created with virt-manager should have a USB +controller by default. In the virtual machine details, select +"Controller USB" in the left pane, and make sure its model is set to +USB2. You can then click on "Add Hardware" and add as many "USB +Redirection" items as the number of USB devices you want to be able to +redirect simultaneously. + +.Using libvirt + +You need to add the needed USB controllers to the libvirt XML (make +sure there is no pre-existing USB controller in your virtual machine +XML before doing this), as well as one Spice USB redirection channel +per device you want to redirect simultaneously. + +[source,xml] +<controller type='usb' index='0' model='ich9-ehci1'/> +<controller type='usb' index='0' model='ich9-uhci1'> + <master startport='0'/> +</controller> +<controller type='usb' index='0' model='ich9-uhci2'> + <master startport='2'/> +</controller> +<controller type='usb' index='0' model='ich9-uhci3'> + <master startport='4'/> +</controller> +<redirdev bus='usb' type='spicevmc'/> +<redirdev bus='usb' type='spicevmc'/> +<redirdev bus='usb' type='spicevmc'/> +<redirdev bus='usb' type='spicevmc'/> + +.Using QEMU + +Similarly to libvirt, we need to add EHCI/UHCI controllers to QEMU +command line, and we also need to add one Spice redirection channel +per device we want to redirect simultaneously. + +[source,sh] +-device ich9-usb-ehci1,id=usb \ +-device ich9-usb-uhci1,masterbus=usb.0,firstport=0,multifunction=on \ +-device ich9-usb-uhci2,masterbus=usb.0,firstport=2 \ +-device ich9-usb-uhci3,masterbus=usb.0,firstport=4 \ +-chardev spicevmc,name=usbredir,id=usbredirchardev1 \ +-device usb-redir,chardev=usbredirchardev1,id=usbredirdev1 \ +-chardev spicevmc,name=usbredir,id=usbredirchardev2 \ +-device usb-redir,chardev=usbredirchardev2,id=usbredirdev2 \ +-chardev spicevmc,name=usbredir,id=usbredirchardev3 \ +-device usb-redir,chardev=usbredirchardev3,id=usbredirdev3 + +Client +------ + +The client needs to have support for USB redirection. In +remote-viewer, you can select which USB devices to redirect in +"File/USB device" selection once the Spice connection is +established. There are also various command line redirection options +which are described when running remote-viewer with `--help-spice`. + +[NOTE] +You may need additional services running in the client, such as the +Spice USB Clerk service on Windows. + +Multiple monitor support +======================== + +When using Spice, it's possible to use multiple monitors. For that, +the guest must have multiple QXL devices (for Windows guests), or a +single QXL device configured to support multiple heads (for Linux +guests). + +Before following the instructions in this section, make sure your +virtual machine already has a QXL device. If that is not the case, +refer to this section. Your guest OS will also need to have the QXL +driver installed or multiple monitor support will not work. + +Once your virtual machine is using a QXL device, you don't need to +make any other change to get multiple heads in a Linux guest. The +following paragraph will deal with adding multiple QXL devices to get +multiple monitors in a Windows guest. + +Configuration +------------- + +.Using virt-manager + +To add an additional QXL device for Windows guests, simply go to your +virtual machine details. Check that you already have a "Video QXL" +device, if notclick on "Add Hardware", and add a "Video" device with +model "QXL". This can also work with Linux guests if your are willing +to configure X.Org to use Xinerama (instead of XRandR). + +If you are using a new enough distribution (for example Fedora 19), +and if your virtual machine already has a QXL device, you should not +need to make any changes in virt-manager. If you are using an older +distribution, you can't do the required changes from virt-manager, +you'll need to edit libvirt XML as described on this blog post. + +.Using libvirt + +To add an additional QXL device to your virtual machine managed by +libvirt, you simply need to append a new video node whose model is +QXL: + +[source,xml] +<video> + <model type='qxl'> +</video> +<video> + <model type='qxl'> +</video> + + +.Using QEMU + +To get a second QXL device in your virtual machine, you need to append +`-device qxl` to your QEMU command line in addition to the `-vga qxl` +that is already there: + +[source,sh] +-vga qxl -device qxl + +Client +------ + +You can enable additional displays either from the "Display/Displays" +menu in remote-viewer, or from your guest OS display configuration +tool. + +TLS +=== + +TLS support allows to encrypt all/some of the channels Spice uses for +its communication. A separate port is used for the encrypted +channels. When connecting through a TLS channel, the Spice client will +verify the certificate sent by the host. It will check that this +certificate matches the hostname it's connecting, and that this +certificate is signed by a known certificate authority (CA). This can +be achieved by either getting the host certificate signed by an +official CA, or by passing to the client the certificate of the +authority which signed the host certificate. The latter allows the use +of self-signed certificates. + +Configuration +------------- + +.Using virt-manager + +IMPORTANT: It's not currently possible to define the CA +certificate/host certificate to use for the TLS connection using +virt-manager, see the next section for how to enable this using +libvirt. + +.Using libvirt + +The certificate must be specified in libvirtd configuration file in +'/etc/libvirt/qemu.conf' (or in '~/.config/libvirt/qemu.conf' if you +are using a session libvirt).

When +using QEMU, '/etc/sasl2/qemu.conf' will be used as a configuration +file. For testing, you can use the `digest-md5` mechanism, and populate +a test database using `saslpasswd2 -f /etc/qemu/passwd.db -c +foo`. These files have to be readable by the QEMU process that will +handle your VM. + +To troubleshoot SASL issues, running `strace -e open` on the QEMU +process can be a useful first step. + +Configuration +------------- + +.Using virt-manager + +It's currently not possible to enable SASL from virt-manager. + +.Using libvirt + +SASL support for SPICE has been added to libvirt mid-October 2013 so +you need a libvirt version that was released after this date. To +enable SASL, you need to add `spice_sasl = 1` in '/etc/libvirt/qemu.conf' +for the system libvirtd instance, and to '~/.config/libvirt/qemu.conf' +for the session libvirtd instance. + +.Using QEMU + +Using SASL with QEMU involves a slight modification of the `-spice` +parameter used when running QEMU: + +[source,sh] +-spice port=3001,sasl + +Client +------ + +When you start the client as usual, if SASL was enabled on the host, +remote-viewer will pop up a window asking for a password before +starting the Spice session. It won't be established if an incorrect +ticket was passed to the client. + +QEMU Spice reference +==================== + +**** +TODO, incomplete +**** + +Command line options +-------------------- + +They are covered in the +http://qemu.weilnetz.de/qemu-doc.html#index-g_t_002dspice-58[QEMU +online documentation].

In order for the agent to work, your virtual machine must +have a virtio serial device (and the corresponding guest drivers) as +well as a Spice spicevmc channel. + +Windows guest +------------- + +The recommended way of getting all the needed drivers installed is to +use the all-in-one Spice guest tools installer which can be found on +http://spice-space.org/download/windows/spice-guest-tools/[spice-space.org]. + +To get USB redirection working on Windows, you need to install USB +Clerk (TODO: add link) + +If you want to manually install them, the QXL driver can be downloaded +from http://spice-space.org/download/windows/qxl/[this location] , +agent builds can be found +http://spice-space.org/download/windows/vdagent/[here]. You also need +the vioserial driver which is distributed with the other +https://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/[ +virtio-win drivers]. + +Installation +============ + +Installing Spice on RHEL or Fedora +---------------------------------- + +Be aware that RHEL has no builds of qemu/spice-server for i386, only +x86_64 builds are available. RHEL >=6 and Fedora >=13 + +[source,sh] +yum install qemu-kvm virt-viewer + +The package spice-protocol will be downloaded automatically as a +dependency of package kvm. + +RHEVM Users +~~~~~~~~~~~ + +oVirt/RHEVM users could be also interested in the spice-xpi package as +it allows you to execute spice-client directly from the oVirt/RHEVM +UserPortal. + +[source,sh] +yum install spice-xpi + +General build instructions +-------------------------- + +This section is for distributions that don't have Spice packages in +their repositories. It will show you step by step how to build the +required Spice components. + +Client requirements +~~~~~~~~~~~~~~~~~~~ + +See the http://cgit.freedesktop.org/spice/spice-gtk/tree/README[README +file in spice-gtk] for the list of dependencies. + +Host requirements +~~~~~~~~~~~~~~~~~ + + * KVM supported by kernel (It should work also without KVM, but it's + not being tested as most Linux distrubitions already support KVM.) + + +Guest requirements +~~~~~~~~~~~~~~~~~~ + +.Linux guest + +spice-vdagent requires virtio-serial support to be enabled. This is +described in the chapter <<agent>>. Guest should have installed qxl +driver (xorg-x11-drv-qxl on Fedora and RHEL). + +.Windows guest + +Drivers for QXL and drivers for virtio-serial require Win XP SP3. + +Building +~~~~~~~~ + +The environment variable `$BUILD_ROOT` will point to a directory with +stored sources and will be used during the whole build process. The +variable `$INST_ROOT` will point to a directory in which Spice will be +installed. + +IMPORTANT: These instructions may be outdated. Feel free to ask on the +Spice mailing list if you need help building from source. + +[source,sh] +------------------------------------------------- +export BUILD_ROOT=/tmp/spice; mkdir $BUILD_ROOT +export INST_ROOT="/opt/spice"; mkdir $INST_ROOT +export PKG_CONFIG_PATH=$INST_ROOT/lib/pkgconfig:$PKG_CONFIG_PATH + +cd $BUILD_ROOT +git clone git://cgit.freedesktop.org/spice/spice +cd $BUILD_ROOT/spice +./configure --prefix=$INST_ROOT +make +make install + +cd $BUILD_ROOT +git clone git://git.qemu.org/qemu.git +cd $BUILD_ROOT/qemu +./configure --prefix=$INST_ROOT --target-list=x86_64-softmmu --enable-spice +make +make install +------------------------------------------------- + +Setting up PATH +~~~~~~~~~~~~~~~ + +Last steps before starting with Spice are to set proper `PATH` +variable. For example RHEL is using /usr/libexec as directory for +qemu-kvm binaries. The following setup should be suitable for qemu and +Spice built according to the instructions in this chapter. + +[source,sh] +------------------------------------------------- +echo "export PATH=$PATH:$INST_ROOT/bin" >> ~/.bashrc +source ~/.bashrc +------------------------------------------------- + +You should now be able to access the qemu-system-x86_64 Spice binary. + +:numbered!: + +[appendix] +Manual authors +============== + +The following people have contributed to this manual: + +Arnon Giloba + +Christophe Fergeau + +Lubos Kocman + +Marc-André Lureau + +Yaniv Kamay + +[[glossary]] +Glossary +======== + +[glossary] +Host:: +Host is a machine running an instance of qemu-kvm. + +Guest:: +Guest is a virtual machine hosted on the host which will be accessed with a Spice client. + +Client:: +Client is referring to a system running the Spice client (the recommended one is virt-viewer). |
