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.

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?

thanks,
