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://
( 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://
- sudo su
- echo 'lxc.aa_profile = lxc-container-
- 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://
- sudo lxc-start -n inner
Fails with: http://
Enabling debug logs for this action yields: http://
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.
