[libvirt-users] Improving video for Windows7 kvm guest on fc14

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 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> How can I more effectively use the video card's capabilities in the Windows guest? Thanks, Alex
