Kvm guests do not start after upgrade

[Nikolai K. Bochev]

Try removing the qemu-kvm and libvirt packages ( don't purge them, or if you do, save your configurations files ).
Reboot.
Install packages again ( best done with aptitude install ubuntu-virt-server if on server or ubuntu-virt-mgmt if you're on a desktop pc ).

This worked for me.
