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.
You and I have nearly identical use cases, interestingly enough. My
laptop that I'm using right now to type this is my development machine
for a number of KVM things I do in the data center as well. Since I run
it docked with ethernet on my desk, but not docked and on WiFi at home,
I've had to do two things:
1.) A real shutdown when I leave work. For some reason I've never be a
fan of suspend/hibernate, and since I use LUKS I'd rather not leave the
volume unlocked as it would be in a suspend/hibernate scenario;
2.) NAT-connected VMs in development, since I've never been able to get
bridging to work properly over wireless (specification says it can't
work, and I think that's true in practice, but I always reserve the
right to be wrong!).
I wonder if it is possible to do what I do on FreeBSD laptop: there I
created link aggregation interface which includes wired adapter and
wireless one (in that priority order), making networking acting "as
smart as macintosh does ;-) ". I'm sure one of Linux Experts can point
us in right direction (at the moment I just use GUI applet to enable
interfaces etc).

My laptop is at least as powerful as most of our servers, and it works
great for development purposes.
