2011-10-28iSCSI block driverRonnie Sahlberg1-0/+31
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

This patch use file system specific ioctl for getting i_generation value. Not all file system support the ioctl.

2011-09-09configure: Avoid duplicate flags when calling compile_progStefan Weil1-1/+1
This patch removes redundant shell code and cleans it a little bit. Shell macro compile_prog takes two arguments: local_cflags and local ldflags. $QEMU_CFLAGS is added automatically to the cflags, so there is no need to pass it as an argument. It is also unnecessary to pass -Werror twice. $flag is a compiler warning option, so it should be in local_cflags instead of local_ldflags.

2011-09-02main: force enabling of I/O threadAnthony Liguori1-13/+0
Enabling the I/O thread by default seems like an important part of declaring 1.0. Besides allowing true SMP support with KVM, the I/O thread means that the TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which currently requires a (racey) signal based alarm system. I know there have been concerns about performance. I think so far the ones that have come up (virtio-net) are most likely due to secondary reasons like decreased batching. I think we ought to force enabling I/O thread early in 1.0 development and commit to resolving any lingering issues. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-08-21guest agent: remove uneeded dependenciesMichael Roth1-0/+3
This patch tries to cull any uneeded library dependencies from the guest agent to improve portability across various distros. We do so by being as explicit as possible about in-tree dependencies rather than relying on existing *-obj-y targets, and by manually setting LIBS for the qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by configure.

2011-08-12configure: Disable guest_agent for mingw32Stefan Weil1-0/+1
guest_agent is not supported for mingw32, so the default value should be 'no', not 'yes'. This removes the dependencies to glib-2.0 and python which makes native and cross builds for w32 much easier (no need to get and install these extra packages). It also avoids the problems caused by different bitfield alignment which is required by glib-2.0. It is still possible to set guest_agent=yes via configure option.

2011-07-26xen: make xen_enabled even more cleverAlexander Graf1-0/+5
When using xen_enabled() we're currently only checking if xen is enabled at all during the build. But what if you want to build multiple targets out of which only one can potentially run xen code? That means that for generic code we'll still have to fall back to the variable and potentially slow the code down, but it's not as important as that is mostly xen device emulation which is not touched for non-xen targets. The target specific code however can with this patch see that it's unable to ever execute xen code. We can thus always return 0 on xen_enabled(), giving gcc enough hints to evict the mapcache code from the target memory management code.

This patch adds support for a usb-redir device, which takes a chardev as a communication channel to an actual usbdevice using the usbredir protocol.
