I just installed a fresh WinXP virtual host on kvm on my Gentoo system. It didn't allow me to use the maximum resolution that my monitor supports (1440x900). So I started reading the kvm manual page, and found the
--std-vga option. After restarting my WinXP machine with this option, Windows was unable to find a driver for the graphics card. Too bad ...
Fortunately Google quickly helped me find one. I came across an interesting post on another blog out there, which pointed me to a VBE 3.0 driver for Windows that works with the KVM/Qemu virtual graphics device.
Thanks a lot, Tom!
