Hmmm... Interesting. That's one area where my systems may be a bit
different that most others. Since I have huge address space to play
with (on IPv4 and IPv6), I generally set my networking up for pure
bridging, instead of NAT. That sounds like the default bridge may not
be set up properly. I think the default uses virbr0 in the host which
is nominally handled by the libvirt stuff for things like dhcp.

Interesting. There may still be something else at play here then.
Still getting the same chroot errors? I haven't been able to reproduce
them at all.

1) Use lxc-console to log into the container and see if it got a network
address for its networking.
2) Use "brctl show" in the host to display the bridge configuration and
if virbr0 shows any connected devices.
3) Check the address of the virbr0 interface in the host.
4) Check to see if libvirt and dhcpd are running.
5) Make sure that you have forwarding enabled in the host.

I'll test some of this out on another host of mine with NAT networking.
