I just performed and 10.04 to 12.04 upgrade on a server (no desktop environment) that had virt-manager installed and I can no longer start that application (I used it very well over SSH on 10.04). I don't know where you are getting that output (virtinst versioning problem). I don't see it. I've uploaded an strace file.
