[Qemu-devel] qxl performance problems and spice issues

[heliman]

Hello,

I am testing Xen 4.2 (unstable) with Qemu 1.1rc2 and spice.
I have severe video performance problems on Windows 7 guest and X fails to run 
on
Debian wheezy and Ubuntu Precise guest.
The problem may be related to Xen and I'm asking there too, but I want to make
sure my invocation is correct as far as Qemu is concerned.

If someone is experimenting with spice and has qxl video, vdagent, audio and usb
redirection working, can you post your Qemu and SeaBIOS version and exact Qemu
invocation, so that I can try to replicate your results.

Are qxl and other spice features dependent on kvm in some way?
Should I use -vga qxl or -device qxl-vga?

Thanks,
LG

Here is Qemu invocation by xl:
