Subject: [ovirt-users] Re: Ovirt host update bug
 
Checked with the networking and looks like the issue is with the conflicting OVS/OVN packages released on the OpenStack channel.

Fixing that on our side will require releasing a new version, but one can try to fix it manually by modifying the /etc/yum.repos.d/CentOS-oVirt-4.5.repo file.

1. Find the [ovirt-45-centos-stream-openstack-yoga] section
2. At the end of the section look for ansible-test under exclude=
3. Add rdo-openvswitch and rdo-ovn each on their own line, in same way as ansible and ansible-test that already exists

There are 3 hosts, which can all detect and begin the update, getting most of the way through it, before failing and returning it to a state of non-operation. The log file says that the host is unable to resolve the virtual switch dependency
