Re: [ovirt-users] Change network of ovirt-nodes of a self-hosted engine cluster

Good day!
I'm in position when I have to change network settings of three ovirt-nodes that
comprise my cluster with hosted engine.
Am I correct that to change network is not a big deal and it is possible?
My plan was:
1. shutdown all vms (except engine itself) on all nodes.
2. enable maintenance mode on all nodes, except the one with running engine
I think you should use Hosted Engine global maintenance while doing this.
If for some reason the gateway configured in hosted_engine.conf become unreachable I'm
not sure it won't try to migrate the VM.
Adding Martin to the loop.
3. change network settings in engine node
4. shut engine down with hosted-engine --vm-stop
5. change network settings on all nodes, verify that nodes can ping each other
6. start engine with hosted-engine --vm-start
7. change VLAN tag at Logical Network for VMs
8. activate nodes
9. start vms
Does it make sense?
