How is screen size handled in kvm/qemu

[Alexander Volovics]

I decided to try out virtualization in Fed 16 + Gnome 3.2 on my laptop.

To begin I chose a small distro 'Crunchbang-10 64bits, based on Debian 
Live with the Openbox WM.

No problems with the install.
But the result is not comfortable because the laptop screen is 1600x900
and the virt manager screen for Crunchbang is 1024x768, the wrong (4:3)
proportionality.

This means that even if I use full-screen I still have a 'small' 
Crunchbang screen.

I this a restriction of virtual graphics or are there (hidden)
configuration options.
