Old Ubuntu .deb?

[kentborg-KwkGvOEf1og at public.gmane.org (Kent Borg)]

There was a new version of libvirt (0.7.5-5ubuntu27.3 -> 
0.7.5-5ubuntu27.6) files on Friday, and this morning I installed them, 
and now all my qcow2 disk images are "not a bootable disk" and kvm isn't 
working so well.

Any suggestions on where one can find old Ubuntu .deb files?  (Anyone 
still have such files in their /var/cache/apt/archivies?)

make the future work, etc., but who first wants to get his virtual 
machines up and running again.
