Wrong. You should not be directly editing anything under /etc/libvirt,
but instead should be using 'virsh edit rmdev2' to make those changes.
It may be because you went behind libvirt's back that your edits were
not recognized, and that you had to end up undefining and re-creating a
new guest before you got this to work the way you wanted.
# brctl show
bridge name bridge id STP enabled interfaces
br1 8000.e41f13ba6e1a no eth1
virbr0 8000.5254003a3124 yes virbr0-nic
# virsh -c qemu:///system start rmdev2
error: Failed to start domain rmdev2
error: Failed to add tap interface to bridge 'br0': No such device
there *nothing* 'br0' in /etc in the system (I grepped it),
why is looking for br0 instead of br1 ?
One other thing to check, although I'm not sure it matters in your case
(since you said that creating a new domain worked): when modifying
network information, you may also need to modify libvirt's notion of the
network, via such commands as 'virsh net-list' and 'virsh net-edit'.
