Bug Description
I create my VMs with virt-manager and tried "Video Modell vmvga" in order to let the VM use my whole screen of 1920x1200. This works with some Ubuntu flavours, but others crash on login:
The host is Ubuntu 12.04.05 LTS, using Gnome-classic as GUI. All VMs were updated to latest state.
All VMs run, when "Video Modell cirrus" is selected, however, this allows only a max display resolution of 1280*1024, insufficient for some graphics work.
But when running "Video Modell vmvga" (all being otherwise identically configured):
Ubuntu Unity 14.04 .................. ok
Kubuntu 14.04 .......
Ubuntu Cinnamon 14.04 ......... shows login screen, crashes on login (this VM was cloned from Unity, Cinnamon then added)
Ubuntu Gnome 14.04..
Ubuntu Mate 14.04.01 ............. shows login screen, crashes on login (installed from fresh download)
Ubuntu Unity has such tiny fonts that usage is almost impossible. Only Kubuntu is usable in that regard, but this crashes occasionally

Please be more specific what yo umean by "crashes on login". Do you have some Apport crash reports which you could upload? If nothing actually crashed, but you just can't see anything on the screen, can you ssh into the VM and retrieve dmesg, /var/log/ Xorg.0. log?
