If you're using manually built qemu or
qemu without kvm then just replace qemu-kvm with your own binary. I'll use host# client#
guest# shell prompt notation to distinguish wherever should be the command executed. See
section <a class="link" href="definitions" target="_top">Basic Definitions</a> to be sure that you know
difference between the host, client and guest. You can ignore notation If guest, client
and host are on the same machine.</p><p>
<span class="bold"><strong>First important thing to do is to create a guest
image.</strong></span> You can use any raw device like clean logical volume, or iSCSI
lun. You may also use file as image for guest. I'll use file created by qemu-img as a demonstration.
</p><p>
Following command will allocate 10GB file. See qemu-img manpage for further information.
</p><pre class="screen">host# qemu-img create /path/to/xp.img 10G</pre><p>
So we already have image created and shall now start with image popullation. I assume that you have
locally stored ISO of your favourite operating system so you can use it for installation.
</p><pre class="screen">host# sudo qemu-kvm -boot order=dc -vga qxl -spice port=3001,disable-ticketing -soundhw ac97 \
-cdrom /path/to/your.iso /path/to/your.img</pre><p>
Let's take just briefly look trough used qemu options. Option -boot order=dc specifies that guest system
should try to boot from first cdrom and then fallback to first disk, -vga qxl specifies that qemu should
emulate qxl device adapter.
</p><p>
There will be no running <a class="link" href="SpiceUserManual-Introduction.xml#vdagent" target="_top">agent</a>
on the <a class="link" href="guest" target="_top">guest</a> system so we don't have to emulate virtio device yet.
