1. validations
1.1. do you block setting a logical network to don't allow running VMs 
if it has a vnic associated with it?
1.2. do you check on import a vnic isn't connected to a logical network 
which doesn't allow running VMs?
1.3. do you check when REST API tries to add/edit a vnic that the chosen 
logical network is allowed to run VMs?

2. changes
2.1 can a logical network be changed between allow/disallow running VMs?
2.2 what's the flow when enabling running VMs? will the logical network 
become non-operational until all hosts are reconfigured with a bridge 
(if applicable)?
what is the user flow to reconfigure the hosts (go one by one? do what 
(there is no change to host level config)?
2.3 what's the flow to not allowing to run VMs (bridge-less) - no need 
to make the network non operational, but same question - what should the 
admin do to reconfigure the hosts (no host level config change is needed 
by him, just a reconfigure iiuc)

Thanks,
