Hello, First, thanks a lot for your good work! We are using LXC in the CONFINE project (confine-project.eu) to provide researchers with a virtualized linux evironment in a distributed testbed.
We found a problem when a container config looks like this (uses the same vlan id for several type=vlan container interfaces): lxc.network.type = vlan lxc.network.flags = up lxc.network.link = eth1 lxc.network.vlan.id = 3842 lxc.network.name = iso0 lxc.network.type = vlan lxc.network.flags = up lxc.network.link = eth2 lxc.network.vlan.id = 3842 lxc.network.name = iso1 Then, during the instantiation of the vlan interfaces an error occurs because the lxc code tries to assign the same name to both of them before it is bound into the container. Maybe you can have a look at the following patch which solves the problem (see also here: https://github.com/axn/lxc/commit/32fb8a007a95ad4beb9d9d7dade032a50f5da0db ) and consider this or an alternative solution for your 0.8.0 branch.
