IIRC, if you only change the IP address and not the hostname, the engine
does not care. You'll naturally have to take care of keeping network access
working (firewalling etc), might need to reboot the engine and/or hosts. I
didn't try that.

the IP address.

Added to the link above. It has no "feature page", as in something under
ovirt.org/Features with the format of the pages there.

Also removed "DRAFT" and a few other minor changes, as what's there is
basically correct.
