[lxc-users] Highlights about veth interfaces and namespaces in LXC

[azoth at vmail.me]

Hello,

we are two students currently working on LXC and more precisely on the 
networking
aspect. At this moment we are trying to understand how the virtual 
interfaces
work, how they are created and removed.

For now, we are focused on the part where the two veth interfaces are 
linked
after their creation.

We know that there are two virtual interfaces which are created on the 
host in a
first time (for example VETHOMB0MG and VETHONT4F7). One remains on the 
host and
the other moves to a namespace (and is renamed to fit containers 
interface name
like eth0 ?). But we cannot get which function in the code is 
responsible for the
link once one of them is in the container.

Does someone have an idea and could highlight us on it ?

We work on the LXC git version. The container is a Debian (Jessie).

We are not sure if this post belongs to lxc-users or lxc-devel. Do not 
hesitate to
advertise us if we are wrong.

Thank you for your reply.
