[Qemu-devel] How to use qemu-kvm with Fedora15-beta gnome3 (better vga driver ?)

[Cheng Renquan]

Hi all,

I'm trying to use qemu-kvm to run Fedora15-beta with gnome3,
but it told me graphics hardware failed to run gnome3 specific
features and it fallback to gnome2;

I checked the qemu-doc and tried all these vga drivers, no one
could work with gnome3, does someone know how to run qemu with
a better virtual graphics hardware ? Thanks,

‘-vga type’
Select type of VGA card to emulate. Valid values for type are

‘cirrus’
Cirrus Logic GD5446 Video card. All Windows versions starting from
Windows 95 should recognize and use this graphic card. For optimal
performances, use 16 bit color depth in the guest and the host OS.
(This one is the default)

‘std’
Standard VGA card with Bochs VBE extensions. If your guest OS supports
the VESA 2.0 VBE extensions (e.g. Windows XP) and if you want to use
high resolution modes (>= 1280x1024x16) then you should use this
option.

‘vmware’
VMWare SVGA-II compatible adapter. Use it if you have sufficiently
recent XFree86/XOrg server or Windows guest with a driver for this
card.

Sorry, none of the cards provided by KVM (including the SPICE-specific 
QXL card) currently provide the 3D acceleration abilities required by 
GNOME 3.

Later when I tried VirtualBox I found VB video driver has such 3D acceleration
abilities, but I just don't like VB style slow performance;

Then are there some plans / possibilities to add more virtual graphics hardware
drivers for qemu kvm ? Any specification to follow? Pointers for me to explore
this way?
