Host Add - Host not found check DNS or /etc/hosts - Users

Thursday, 18 March 2021

Fresh install CentOS8 Streams.  Gluster wizard runs and deploys.  Engine installs on
node.

I copy over /etc/hosts  for primary site resources to ovirt engine so it can find primary
cluster nodes without DNS being booted / up at that time.

I check ovirt engine can ssh to the three nodes... so as root I generate SSH key and do
ssh-copy-id  to all three nodes.

So as much as I can validate communication is working..  i have.

When I "add host" -> use FDN -> input root password 

But it shows up in GUI host list with "install fails" 

Only message is :
