Thanks for reporting this bug and helping to make Ubuntu better. This looks to be a bug in the rmap_remove() function in the kernel kvm module. Unfortunately that part of the code has changed quite a bit so this could be tough to track down. To help narrow things down, can you tell us when was the first time you encountered this? Had you been running for a long time on lucid before that with no problems? And is there anything in particular which you can do in your guest to reliably reproduce this?
