Thanks @Xavier.
"When the hosted engine is in the setup process, the VM is given an IP from a random
192.168.xxx.xxx IP address. This is done in order to provide connectivity between the
host
and the engine temporarily." - I could not get this (please forgive my ignorance).
During the setup process, I choose the VM to have the IP from the DHCP. Why is (should be)
there a requirement for a temporary ip for the VM as it will get the IP straight when it
is created and completed the boot process?
Anyway, I dont bother as long as it does not affect the oVirt cluster in the long run.
However, I have another issue with the installation (as specified in the main thread).
