[Qemu-devel] Questions about Spice pv domUs

[Fabio Fantoni]

I'm trying to implement basic spice support on xen pv domUs.

Test seems ok on Ubuntu 12.04 pv domU except mouse which is not visible.
I also tried agent-mouse=off on qemu spice options but is not working or 
maybe spicy (from spice-gtk 0.20) has problem in this case (option to 
grab mouse is already enabled).
I can't add vdagent for now on pv because it hasn't  pci support.
Are there xen parts which may give problem with mouse or couldn't be a 
xen related problem?

Qemu parameters on my test was:

I have also another question for qemu/spice developer: I tried to change 
qemu -vga parameter to -device but isn't working and I not found nothing 
on docs or man. Is xenfb available with new qemu parameter -device?

Thanks for any reply.
