Thanks anyway.
I gave it a try....
Taking the packages i currently have on my updated F15 beta I rebuilt:
- libdrm with  --enable-vmwgfx-experimental-api option
- mesa with --enable-gallium-svga and adding xorg in the line
--with-state-trackers=dri,glx,xorg

So now I have all the sw parts compiled...
I configure vmvga as adapter but it seems it doesn't work.

Could it be that the emulated vmvga in qemu/kvm hasn't the
capabilities required (I guess this watching the probe error in
messages...)?
I eventually will try on vSphere to see if the same configured os vm
can go through this...

Thanks for any pointer anyway.
