[ovirt-users] Attaching ISO to hosted engine for OS upgrade

[Chris Adams]

I'm working on upgrading an oVirt 3.5 setup.  The physical hosts are
running CentOS 7, but the hosted engine is CentOS 6.  The upgrade notes
are "back up the engine, upgrade/reinstall the OS, then restore", but I
can't see how to actually install CentOS 7 on the engine.

Am I supposed to re-run "hosted-engine --deploy"?  Wouldn't that try to
re-register the physical hosts, or can I interrupt it to restore the
backup?

Or, is there a way to just attach an install ISO to the engine VM and
boot from that?
