Yes, we can do these manually if we are the master of the system
This is the administrator's job to configure hypervisor hosts.
But I think we should provide a UI to the user and VDSM
management API in the backend.
Simple users changing Host networking? I think it's not a good idea.
Also, it is a quite a challenge to
assign the VMs in different host to the same vlan.
Maybe you wasn't clear enough. The settings I mentioned are talking about configuring
__hosts__, not VMs.
All the hosts in a cluster must have configurations to see all the logical networks
assigned to that cluster. This way, a VM that uses a specific network can easily migrate
between hosts without losing networking
