Do you have a ifcfg-br0 in your LXC configuration? If the VMs can see each

Yes, I have a ifcfg-br0 file in my LXC configuration. It's identical to
what I use with my libvirt-LXC setup. In my particular case, I have the
bridge connected to a bonded interface, but it works the same as if I
was to connect it to a hosts eth0. This lets me bond say four nics
eth0-3 into one bond0 interface. The is connected to the bond0 interface
but from its perspective it acts the same as an eth0 interface. I need
to of course maintain this configuration in moving from libvirt-LXC to LXC.
Ultimately, in the long term, I will want to remove the entire set of
libvirt packages from my setup and only install the LXC rpms. I know
that LXC was developed by Canonical but my impression was that it would
work under CentOS/Fedora as well. Unfortunately I'm not that familiar
with Ubuntu networking and a lot of the examples appear to be specific
to Ubuntu.
For example, I see references to the file /etc/network/interfaces. Is
this an LXC thing or is this a standard file in Ubuntu networking?
Mark Constable asked a related question stemming from my original post
and commented on the file /etc/default/lxc-net. I assume this file is
*not* specific to Ubuntu. Do I need to create this file in my CentOS setup?
It might be useful to configure a CentOS system without libvirt
installed and do some LXC tests without libvirt-LXC getting in the way.
I was hoping making the move to LXC wouldn't be too painful but it looks
like I'm going to have to work for it a bit.
