[ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

Tue Mar 13 16:22:07 UTC 2018

I'll work on it some more.  I have 2 different clusters in the data center
(1 is the Hosted Engine systems, another is not..)  I had trouble with
both.  I'll try again on the non-hosted engine cluster to see what it is
doing.  I have it working in 4.1, but we are trying to do a clean wipe
since the 4.1 engine has been upgraded so many times from v3.5 plus we want
to move to hosted-engine-ha from a single engine node and the ansible
modules/roles (which also have problems..)
