This has been requested in the past already (even by me ;-)
Renaming is not that simple, as there are several more things to do:
1. Rename log files (this was somehow controversial last time it was
discussed, especially combined with external programs like logrotate)
2. Fix domain config for suspended VMs.
3. Keep existing snapshots
3.1 Fix domain config in snapshots.

Especially the last thing does very bad things if you revert a renamed
VM, as the UUID is then no longer unique.
