I've got an environment set up now where the host OS has a static IP
directly connected to the LAN. I'm bridging the containers to have their own
static LAN IP as well.
In my containers I've set:
lxc.network.type=veth
lxc.network.link=br0
lxc.network.name=eth0
lxc.network.ipv4 = 10.1.3.21/16
lxc.network.flags=up
When I start my container eth0 is *not* configured. If I manually add
`eth0=eth0` in /run/network/ifstate and `service restart networking`, it
gets configured properly.
davidparks21@Myrrix:~$ dmesg | grep eth0
[ 3.185536] igb 0000:01:00.0: >eth0: (PCIe:2.5Gb/s:Width x4)

[ 13.987626] br0: port 1(em1) entered forwarding state
[ 13.987632] br0: port 1(em1) entered forwarding state
After looking at dmesg output I noticed that there are (unexpected)
references to em1, which is the host's physical NIC.
The bridging all works, networking is fine, it's just when I start the
container, rebooting reproduces the problem, then manually updating ifstate
and rebooting resolves it.
I'm not sure how to configure it so it configure eth0 on reboot as I would
expect.
Thanks for any advice!
David
