Screen resolution options for a virtualized Windows using a VirtIO graphics card

[Tobias Leupold]

Hi all!

When virtualizing e.g. a Windows 10 installation with QEMU and using the 
default graphics card (with no command line option set), it shows up as a 
"Microsoft Basic Display Adapter", and one can choose from a lot of 
resolutions:

    1920 x 1200
    1920 x 1080
    1680 x 1050
    1600 x 1200
    1440 x 900
    1280 x 900
    1280 x 1024
    1280 x 960
    1280 x 800
    1024 x 768
    800 x 600

even more on Windows 7. When adding a VirtIO graphics card via "-vga virtio" 
or "-device virtio-vga" and installing the respective drivers, the card shows 
up as a "Red Hat VirtIO GPU DOD controller", and most of the options are gone:

    2560 x 1600
    1920 x 1080
    1280 x 1024
    1024 x 768
    800 x 600

Is it possible to get more resolution options for a VirtIO grahics card?

Thanks for all help!

Cheers, Tobias
