My setup is RHEL 7.4, with the host separate from the engine.
The ovirt-release42 rpm was added to the engine host, but not to the virtualization host. The vhost was still running v4.1 rpms. I installed ovirt-release42 on the vhost, then updated the rest of the rpms with "yum update". I am still getting an error on activation of the vhost...
Host parasol does not comply with the cluster Intel networks, the following networks are missing on host: 'data30,data40,ovirtmgmt'
It seems like the networks bridges are not there anymore??
