It is OK if your KVM host is on LAN cable that never is disconnected or
power goes down.
But I have a laptop I use first at work where I use LAN and then at home
where I use WLAN only, and suspending laptop is same as disconnecting
LAN, bridge is disabled and KVM bridged network unhooked, and you can
never reinitialize it without at least restarting kvm, and full
treatmant is shuting down VM, restarting NM then network then starting
VM again... So I just shutdown VM and laptop and boot everey itme I
move. Maybe I can change this behavior now.
