set/change ethernet link state
|Category:||Core & System|
A nice feature in virtualbox/vmware is the capability to change the state of the Ethernet link (active, disconnected).
It is already possible to set the link state in libvirt through <link state"up|down"> (useful for example when you are testing whether a snapshots boot, but you don't want to have the VM to advertise on the network). It is also possible to change it live through virsh's domif-setlink command;
I think it may be a useful addition to the network definitions, along with a button in the VM/net pane to change the Ethernet state on-the-fly.
