When creating a new host using a hostgroup that defines the cluster the available vlans are not updated to reflect what is available within the cluster.

Cluster A has (vlan1 vlan2)
Cluster B has (vlan3 vlan4)

When you create a new host using a host group that sets Cluster B, the list of available vlans in Interface in the oVirt section is limited to vlan1 and vlan2.

We are working around this by manually setting Cluster to A and back to B to correctly populate the list of available vlans.

Please let me know if there is any additional information I can provide.

Thank You
