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.

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: http://www.ovirt.org/Changing_Engine_Hostname > > There really needs to be some work done in Ovirt on making it easier to > import existing disk images and just generally moving things around > without having to bounce off an NFS server. > > Should I do a BZ on that? Not sure what you mean exactly, but you are always welcome to open BZs on bugs/RFEs... Best regards, -- Didi Sorry for going slightly off topic, but how is everyone's hosted engine deployment going? Are you restricted to NFS?

I tried the migration procedure last month and it worked.. but had quite a lot of issues so I ended up reverting back. I didn't open any bugs in the assumption it was in super alpha stage.
