I didn't try that. In principle it can. Note that it will only backup/restore
the engine - not local storage domains (ISO or data), VM images, etc.

If you try that, please report back. Thanks!

Changing the hostname is specifically not in the scope of engine-backup.

Note that you do not need to have the hostname equal to the "fqdn" input
during engine-setup - this last one just needs to be dns-resolvable and
point to the machine intended.

Also, there is another utility to do that, called ovirt-engine-rename -
see this for details and implications:

Not sure what you mean exactly, but you are always welcome to open BZs on
bugs/RFEs...
