After updating to the latest packages, this issue is solve. I can lxc- start, lxc-attach, lxc-stop, and lxc-execute.
I do get some warning/error spew when running lxc-execute though. If this looks unexpected, I can open a separate bug for it: $ lxc-execute -n t1 -- /bin/bash lxc-execute: utils.c: safe_mount: 1691 Invalid argument - Failed to mount /sys/kernel/debug onto /usr/lib/x86_64-linux-gnu/lxc/sys/kernel/debug lxc-execute: utils.c: safe_mount: 1691 Device or resource busy - Failed to mount mqueue onto /usr/lib/x86_64-linux-gnu/lxc/dev/mqueue init.lxc.static: initutils.c: mount_fs: 36 failed to mount /proc : Device or resource busy init.lxc.static: initutils.c: mount_fs: 36 failed to mount /dev/mqueue : Device or resource busy The first two of those show up in the container log file upon lxc-start too: lxc-start 20160316211700.325 ERROR lxc_utils - utils.c:safe_mount:1691 - Invalid argument - Failed to mount /sys/kernel/debug onto /usr/lib/x86_64-linux-gnu/lxc/sys/kernel/debug lxc-start 20160316211700.325 ERROR lxc_utils - utils.c:safe_mount:1691 - Device or resource busy - Failed to mount mqueue onto /usr/lib/x86_64-linux-gnu/lxc/dev/mqueue Thanks very much for fix and bug comments; this has been one of the most productive bug reports I've ever filed:-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1556447 Title: lxc-start fails: lxc_cgfsng - cgfsng.c:all_controllers_found:430 - no systemd controller mountpoint found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1556447/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
