ohad (oVirt Host Agent Daemon, and that's also an Israeli name), or just
oha (not to be confused with the Office of Hawaiian Affairs)
ohanha (oVirt Host Agent Not High Availability , and that's also an Israeli
family name, mostly known for some past famous Israeli soccer player)
ohd  (oVirt Host Daemon), far enough from OCD.
