Sorry Shin, I meant to get back to answer this when you asked, but got distracted and then
forgot about it (which was rude of me - sorry). I also needed to "document it for
myself" because, over a year later, I've ran into the same issue (see
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/7CXIPLSXOGL3...).
In short, (to now answer your Q and to document it for me, plus anyone else who runs
across this) the solution (for me) was to accept the default names for the Data Center and
the Cluster and then edit the names to what was required/desired once the engine was
successfully deployed. This thread
(
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IDLGSBQFX35E...)
gave me the clue (the 2nd time around).
Cheers
