Hi,
I have an existing windows7 x86_64 kvm guest running on fedora14
x86_64 with a Radeon HD5700 at 1680x1050, and would like to improve
the resolution and video response of the Windows guest. How can I
change the Windows
driver to something more capable than "standard vga"? It currently
reports there is only 16MB of RAM at available at 1440x900. How can I
increase this? I've tried using virsh or editing the xml directly, but
it doesn't seem to be reflected in the guest.
Some of the configuration options I've read in the documentation don't
work with fedora14 and virt-manager, such as the acceleration options.
This is my current configuration:
<video>
<model type='vmvga' vram='192000' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x02'
function='0x0'/>
</video>
Video response is very slow and the mouse is also sluggish.
How can I more effectively use the video card's capabilities in the
Windows guest?
Thanks,
Alex
You could use spice under Fedora 14, but you'll have to configure qemu
directly. (-vga qxl).
-However-, the qxl driver for Windows 7 / x86_64 is unsigned, which
means you cannot use it under Windows 7 without disabling the driver
signature enforcement every-time you boot the guest (F8 during boot;
disable driver signature enforcement).
