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.
i don't recall the steps for 3.2, but worth mentioning that in
3.3 this
should work via:
http://gerrit.ovirt.org/17408
http://www.ovirt.org/Changing_Engine_Hostname
It provides a script
/usr/share/ovirt-engine/setup/bin/ovirt-engine-rename which allows
changing the engine's hostname.
Indeed. And this script is only needed when changing the hostname, not
the IP address.
It's otopi-based. This means, among other things, that it looks similar
to the new engine-setup/cleanup, and provides similar logging, options, etc.
Options specific to it:
--newname=<newname>
An example run, which does everything in batch and does not ask
questions, if possible:
/usr/share/ovirt-engine/setup/bin/ovirt-engine-rename
--newname=ovirte1n.home.local
--otopi-environment="OSETUP_RENAME/forceIgnoreAIAInCA=bool:'True'
OVESETUP_CORE/engineStop=bool:'True'
OSETUP_RENAME/confirmForceOverwrite=bool:'False'"
didi - i think above example should be added to the wiki feature page?
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.
