[ovirt-users] Change Vlan ID's which are connected to the Host/VM's

Sun Feb 19 13:10:06 UTC 2017

Hi Matt,

It won't work.
The name is the key for the sync operation. So it cannot be out of sync.

If you change the name via the db (which is highly not recommended!), the
network will be considered as a new one.
You will end up (after refreshing the capabilities) with unmanaged network
in the hosts (the network with the old name) and new network in the
dc/cluster that is not attached to any host.

Alona.
