Bridge for VM's is main reason I hate NM. I now mess with both NM and
br0 controled by network because I use Windows VM on my laptop. As soon
as you disconnect LAN cable your eth and bridge connection are gone and
stupid KVM can not recover and reconnect to newly activated bridge when
you return LAN cable, even only a second later...
