Hi, I have an oVirt 4.2 environment running with the engine in hosted engine state. We are now going to change our whole setup migrating to redundancy on switch side and using a different VLAN for the ovirt management traffic. Currently all host and management-traffic is running untagged on one network interface on all of our hosts and we want to change this to be VLAN-tagged inside LACP-Bonds (each bond containing two network interfaces) on all hosts. While changing the configuration for the VM networks should be straight forward as I can shutdown all VMs during the migration I'm asking how to handle this for the hosted engine VM and configuration. Is there any information how to do such a change? Regards Bernhard
