Restore backup to KVM

[solitone <solitone@mail.com>]

It's time to test my backups. Apart from user files, I also back up 
system files, except for the following directories that are excluded: 
/dev, /lost+found, /media, /mnt, /proc, /run, /sys, /tmp.

I would try and restore them to a virtual machine (KVM). Would it be 
possible? Is there a way to configure KVM so that it resembles my bare 
metal, and the test is significant? I would install a basic debian 
system in KVM, and then overwrite it with my backed up files. Is this 
approach correct?

Cheers!
