'phys' interface does not come back after lxc-stop

[Avijit Ghosh]

Running 'lxc 0.7.5-3ubuntu65' on 12.04.1 LTS [Precise Pangolin]

Created a container with lxc.network.type=phys. I start the container [ok], stop the container [ok], start the container again -- it fails with error message 'Failed to retrieve index for eth1'. Turns our 'eth1' was renamed 'dev3' and was not renamed back.

This is actually the same problem as bug #764278 -- only bug #764278 was reported for Lucid and I am getting it on Precise kernel version 3.2.0-29-generic-pae. For #764278, it was marked 'invalid' with reason 'lxc isn't supported on lucid' and 'is fixed in newer kernels. Apparently not.

(Note that if lxc.network.name is not specified (or is the same as lxc.network.link) then this doesn't happen, which is a workaround for this)

There is currently no code in lxc renaming the nics at container shutdown. That needs to be added.

This has been fixed in the upstream staging tree. The fix should be merged into raring as soon as 0.9.0 is released and merged.
