Brett,
Does your /etc/resolv.conf contain the correct dns's?
If not, please update them.
If you need to override the changes done to the ifcfg files, you can use the
hooks
to introduce your own custom changes. You can find an article describing this in
more details here:

Hello,
The problem with ovn ( 'br-int': No such device) occurs because you are
missing an ovs bridge named "br-int" on your host.
This is the integration bridge used by ovn to create its logical networks.
This is normally created by default during ovs/ovn installation. Please try
adding this manua
Hi Carl,
Glad to hear it helped, and thanks for the description.
May I ask why you want to channel the traffic through
one host?
This solution has a disadvantage of pushing all outfgoing
traffic from the OVN network through a single host, which
is not quite optimal for performance. It would be int
The OVN tunnels are set up during host installation, when
only 'ovirtmgmt' is available (no other networks are created
yet).
You can change the tunneling network for a cluster by using
the procedure described below. This will hopefully be integrated
into the UI one day.
1. Go to:
cd /use/share/ovi
host-141 should only resolve on the interface you selected to create the
management bridge.
Please check your /etc/hosts and /etc/resolv.conf for problems

Hi Gianluca,
The provider in version 4.1 was installed automatically, but it did not

Hence if you try to install it in 4.2, it will try to install itself again

The proper setup in your case would probably be to create br-int and connect
