Hi,

I deployed an HCI of three nodes using ovirt 4.3 on a flat network at the beginning, now we need to use VLAN on the management network.

I have ovirtmgmt over bond2, this bond will have three vlans : vlan 10 for management, vlan20 for DMZ and vlan30 for DMZ2.

On the switch, I did configure the concerned ports to support ; the native vlan (untagged), the vlan10 (tagged), ...etc.

Then I activated the tag on the ovirtmgmt network on the web UI, I did lose connexion to the hypervisors and things got weird, I then put my machine on vlan10, I saw that two of my hypervisors had their network configuration modified to use the vlan10, but not the hypervisor where the VM-engine was running.

I created the vlan manually on that hypervisor, then I started the VM-Manager, all hosts were recognized.

Then I stopped, then started the platforme again. Still the same problem, two hosts are correct with their vlan : bond2.10 created, but the third no vlan.

Doing the configuration manually works, but it does not survive reboot, is there a way to force vdsm to accept the new configuration on that faulty host?

Regards.
