I wonder which version it is - the "debian package". Are we talking
about kvm-72 from debian lenny perhaps?
Current version is 0.12.4-1, which is upstream 0.12.4-1 with a few
bugfixes (such as >1Tb block device corruption). I'm not sure how
that one might be "dogdy" or snapshotted at a bad time.
Thanks!
