Hi all,
I use libvirt/kvm for my virtualization needs and have a little scerio in mind that I want to implement: a small linux box boots up, launches an X session and after that launches a virtual machine with a fullscreen sdl window, With this I hope to achive several goals: user gets a familiar experience with guest os ( I had windows in mind), near native graphics responsiveness ( we deploy cctv video servers and viewing live video in a virt machine is a must) and security based on isolation from i/o ports.
But when I tried this scenario with
<graphics type='sdl' display=':0.0' xauth='/home/stein/.XAuthority'/>
<graphics type='sdl' display=':0.0' xauth='/home/stein/.XAuthority'/>
in xml file I got:
linux-aeo3:/etc/libvirt/qemu # virsh start wintest
setlocale: No such file or directory
error: Failed to start domain wintest
error: internal error: early end of file from monitor: possible problem:

Even if I disable audio and get rid of alsa problems, I still get Could not initialize SDL(No available video device) - exiting error.
What am I doing wrong?
Please not that lauching qemu-kvm with sdl window goes without problems.
Thanks in advance!
