[lxc-users] Determine which vethXXX interface is connected to particular LXC container

[Rahul Rege]

yea, as suggested by Luis, set it beforehand so you know what connects
where.

if you are using the default stuff then on host run run :

ethtool -S <vethif>

Which will give you the ifindex of veth peer inside container which can be
matched using :

lxc-attach -n <name> -s NETWORK -- /sbin/ip link show eth0

You'd need to iterate though through all and then match them up. Or may be
there could be an easier way which'd directly give you that


Thanks
