Last day I upgraded my Ubuntu 11.10 desktop to Ubuntu 12.04. I was running a KVM virtual about 7 machines and managed by virt-manage software.

Anyway when I finished upgrading I found that virt-manager is not working. So I had to reconfigure it again and install some other missing packages that was deleted! Eventually, I managed to solve this issue.

Then I started to restore my virtual machines. I restored 2 machines without any problems. The third and fourth ones (Windows) made a check disk that lasted more that 6 hours but finally it worked. Other machines I can't find their attached hard disks. I don't know what happened but I can't find those files.

  1. Does upgrading delete files?
  2. Is there anyway to restore those files?

yes sure you will loose all softwares that are not in the box of the new version which is ubuntu 12.04
for example if you installed virt-manager on top of ubuntu 11.10 you will loose at least the libvirtd service and its configuration files

unfortunately they will be lost. So you need a third party programs for recovery. Check r-linux –  user91632 Sep 20 '12 at 14:23
