[ovirt-users] Host compatibility issue after upgrade from 4.2.8 to 4.3.0

I have a three node (hyper converged) cluster, all hosts are identical hardware wise, however after the upgrade one of the three is getting kicked out of the cluster with the following error: Host is compatible with versions (3.6,4.0,4.1,4.2) and cannot join Cluster... The hosts have SandyBridge processors but do have SSBD: CPU Type: Intel SandyBridge IBRS SSBD Family. virsh -r capabilities | grep ssbd <feature name='ssbd'/> The only other thing I should mention is that I *may* have change the cluster compatibly level to 4.3 while this particular node was in maintenance mode (don't know if that has any influence on this issue). Any help getting this node back into the cluster would be greatly appreciated. Ron.
