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). * src/lxc/lxc_container.c src/lxc/veth.c src/lxc/veth.h: do the clone and then renames interfaces eth0 ... ethN to keep the interface names familiar in the domain
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
