[pkg-lxc-devel] Bug#883163: lxc.network.0.link configuration value is ignored

[Salvador Fandiño]

Package: lxc
Version: 1:2.0.9-4
Severity: important

Dear Maintainer,

When configuring lxc containers to have a network interface, I can put
the following entries on /var/lib/lxc/foo/config:

lxc.network.type = veth
lxc.network.name = eth0
lxc.network.flags = up
lxc.network.link = br0

The network interface for the container is attached to bridge br0 and
everything works as expected,

Now, if I want to add more than an interface to my container,
following the documentation, I would change that for this entries:

lxc.network.0.type = veth
lxc.network.0.name = eth0
lxc.network.0.flags = up
lxc.network.0.link = br0

But in this case, the lxc.network.0.link seems to be ignored, because
the container interface does not get attached to the bridge.

BTW, in the later case I can manually add the container interface to
the bridge using "brtcl addif" from the host in order to get the
interface working.
