[Lxc-users] lxc container messing with hosts networking

[arkaitzj at gmail.com]

I've setup a web server and do requests each 5 seconds from my laptop.
Then start tcpdump in the host machine and after a while I do lxc-start.

Inspecting later with wireshark, it looks like once the lxc guest finishes
DHCP negotiation and setups the local IP address(10.0.2.17) any request to
the host IP(10.0.2.15) is identified by the system as "Unicast to another
host" and it sends the packet again trying to forward it, previous to the
lxc guest dhcp it used to identify them as "Unicast to us" and answered
them.

The hosts br0 doesn't change the MAC at all as I can see it the same through
ifconfig br0 in the kvm console window, besides, I'm setting the hosts eth
mac address to very low so that it does not trigger any bridge mac update.

Any hints?
