Ok, I had rebooted the system to do this before. It did NOT work. Now, I
just did the virsh and it worked. I also had my wlan0 come up without
proper IPv6 when I rebooted even with IPV6INIT=yes in the file for it.

So, even though I restart wlan0 from rc.local, I get this:
Jun  8 14:56:00 HC kernel: [   14.219624] ADDRCONF(NETDEV_UP): wlan0:
link is not ready

So, no IPv6 address. And radvd claims it isn't started and isn't running.

After restarting from rc.local wlan0 has fe80, but not 2001 address
assigned.

However, virbr0 got it right this time.

Thank you,
Trever
