Successfully installed f19 x86_64 guest desktop via pxe. Vm configured in oVirt as other linux run yum update after install qemu-kvm process command line on host for this VM contains: -vga qxl -global qxl-vga.vram_size=671088 On F19 VM xorg qxl driver automatically installed and used and also spice-vdagent I had to manually install ovirt-guest-agent from standard fedora repo --> perhaps it would be nice to have it some sort of automatically installed in oVirt guest... how? I put guest in full screen, aka in my setup 1680x1050 Able to use gnome 3 even if quite slow. As soon as I start firefox and begin to use it I get this in Xorg.0.log ...
