ok, so now i think all devices are converted to new qemu syntax.

for video card, we can have just -vga parameter as -device syntax is incomplete for the moment (and a little buggy with my first tests with windows).

I had verified with libvirt, they also use -vga to defined video card.


I had made some test with spice (with qemu on ubuntu with spice compiled),
we need sound card to have sound in spice.
also, you can add up to 12 video card, for multiscreen :)


so maybe for the future, it can be good to keep free 1 pci addr for sound and 1 pci addr for a second video device. (dual screen may be enough i think).


for memory ballooning, i'll make some tests with other virtualations systems to see how they use it. Also i had see that redhat is working on real dynamic memory, so wait and see .


Do you see something else missing ? 

Next step is to add addr mapping to devices.

Sure ;-)

OK, so lets call it hostpci.
