Hello Chris, or anyone else affected,

Accepted lxc into vivid-proposed. The package will build now and be

hours, and then in the -proposed repository.

Please help us by testing this new package.  See

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag

Title:
  Regression: Nested LXC is broken on Vivid

Status in lxc package in Ubuntu:
  Fix Released
Status in lxc source package in Vivid:
  Fix Committed

Bug description:
  The nested LXC functionality seems to be broken on Vivid, at least
  with the following setup:

  Vivid (Host) -> Trusty (Outer LXC) -> Trusty (Inner LXC)

  What happens:

  The Inner LXC start command fails when trying to start with: http://pastebin.ubuntu.com/10682639/
  ( 631 cgroup error?  100 cgroups with this name already running seems to be the revelant error message).

  What is expected to happen:

  The inner LXC start command is expected to succeed and result in a
  running nested container.

  Steps to reproduce:

  - Install vivid server daily, update.
  - sudo apt-get install lxc
  - sudo lxc-create -n outer -t ubuntu -- --release trusty --mirror=http://ch.archive.ubuntu.com/ubuntu -b $USER
  - sudo su
  - echo 'lxc.aa_profile = lxc-container-default-with-nesting' >> /var/lib/lxc/outer/config
  - exit
  - sudo lxc-start -n outer
  - (SSH to outer)
  - sudo apt-get update && sudo apt-get dist-upgrade
  - sudo apt-get install lxc
  - sudo lxc-create -n inner -t ubuntu -- --release trusty --mirror=http://ch.archive.ubuntu.com/ubuntu -b $USER
  - sudo lxc-start -n inner

  Fails with: http://pastebin.ubuntu.com/10682639/
  Enabling debug logs for this action yields: http://pastebin.ubuntu.com/10682658/

  Control: The exact same scenario works on trusty and utopic. Tested by
  spinning up server installs (from isos) in KVMs and verifying
  manually.

  Any further log or information available on request, including KVM
  images demonstrating the problem.
