I ran:
 virsh edit NAME
then changed <source network="default" /> under <interface type="network">

Ah. This isn't what I expected.

In ESX I can change the vlans for a network device without a reboot. I
suppose I can do the same with kvm - I just alter the configuration on
the host; but this feels like something virt-manager should expose. Is
this planned?

Just a few observations so far:
1. gfs/iscsi/nfs docs missing from rh virt guide - got a trunk version
somewhere?
2. virt-manager appears unresponsive/dead if you forget you're in a
vnc window somewhere. would be good to have some feedback (a beep or
whatever) if that happens
3. if you have lots of windows open, and try to open a vnc console for
a guest for which you already have a vnc window open, there is no
feedback. would be good if the vnc title bar flashed or (better) got
focus or something.
