Last night's Lucid kernel update broke kvm. None of my vms (via virt-manager) start. The console goes black and that's it. I know it's not a vnc/console issue because the vms are never pingable or ssh-able. Host is an intel i7 920 running Lucid. Guests don't matter: debian, windows 7, une, fedora, ubuntu all stop at exactly the same place. Even booting lucid 64bit live desktop stops at the same place.

barry see my bug raised a little while before yours today:
#589163
Note the important thing is that almost immediately on start the CPU(s) assigned to the VM peg at 100% utilisation and stay that way until a force off.
Only way I have got my VMs working is to revert to 2.6.32-21
The only KVM related thing between -21 and -22 is apparently the fix for CVE-2010-0419
Unfortunately I don't have a machine spare to build on debian to check the behaviour from upstream directly with no ubuntu packages...
