Re: [libvirt] [PATCH] LXC allow container to have ethN interfaces

Current implementation of lxc driver creates vethN named interface(s) in the host and passes as it is to a container. The reason why it doesn't use ethN is due to the limitation that one namespace cannot have multiple iterfaces that have an identical name so that we give up creating ethN named interface in the host for the container. However, we should be able to allow the container to have ethN by changing the name after clone(CLONE_NEWNET). The patch simply does that and numberes to ethN with ascending order from zero with no concern for what vethN is named. So say if there is one interface, its name will be eth0. Note that this patch is based on top of the prior cleanup patches.
