[ovirt-users] Renaming or deleting ovirtmgmt

[Michael Burman]

I was referring to situation in which the host was there before, but you
need to re-install it to the new cluster with the new management network.

No package removing is needed at all. Why would you do steps 2-4? no need.
Step 5 should work.

I'm not sure i understand what you mean by ' still I cannot remove the
default ovirtmgmt network from that cluster'??
Do you want to detach it from the cluster?
Do you want to remove it from the DC?
Note that you can change the management network role only if the cluster
has no hosts in it.
