Did you have problems with engine-backup? Or had other reasons to not
use it? Thanks!

Can engine-backup be used to move an AIO configuration from one host to
another?

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!

I currently need to move an AIO configuration from AMD hardware to Intel
I7 hardware. The engine-backup WIKI discusses backups, but not
restores. I am a bit concerned about using engine-backup to restore an
AIO configuration to a different system as another WIKI page with
step-by-step instructions to do what engine-backup does for you,
mentions you have to do some extra steps if you are changing hostnames
as the hostname of the ovirt-engine is embedded in the database.

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...

Sorry for going slightly off topic, but how is everyone's hosted engine
deployment going? Are you restricted to NFS?

Andrew, in general I get positive feedbacks from RHEL users. For Fedora
and other distros, this should be in a better situation in the following
1-2 weeks when we'll have 3.4 beta available.
I'd love to get your feedback on it.

I missed your NFS question, sorry;
Yes. Currently we have NFS limitation and we will do our best to see
if SAN can be added. Note that time is not on our side for 3.4.

worth mentioning you can use hosted engine on an iscsi/FC cluster - just the hosted engine VM needs to be on 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.

Next time please open bugs... That's the best way to improve the project,
regardless of the version state. If unsure, you can always try irc / this
list
first to see if this is a known issue and if there are workarounds.
