[Bug 981955] Re: lxc-execute does not seem to work in precise
How did you create this container? If I do: sudo lxc-create -t ubuntu -n e1 sudo chroot /var/lib/lxc/e1/rootfs apt-get update sudo chroot /var/lib/lxc/e1/rootfs apt-get install lxc sudo lxc-execute -n e1 /bin/echo hi I get lxc-init: failed to mount /dev/shm : No such file or directory hi If you don't install lxc in the container, you should get an error about not being able to execute lxc-init, but the error about not executing (null) is simply odd.

Re: [Bug 981955] Re: lxc-execute does not seem to work in precise
Hi, the wiki page I was following had no container, it was using an implicit one or something - that gave me the impression it could just act as an isolation layer around / , isolating only the things configured (e.g. dev access, or networking). That said, lxc-execute with an ephemeral mode looks like it would do exactly what LP needs for test running :) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/981955 Title: lxc-execute does not seem to work in precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/981955/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 981955] Re: lxc-execute does not seem to work in precise
Sorry for the incomplete info I am using a container without rootfs. Just type for a not existing container test: $ sudo lxc-execute -n test /bin/echo hi lxc-execute: Invalid argument - failed to get real path for '(null)' lxc-execute: failed to pin the container's rootfs lxc-execute: failed to spawn 'test' lxc-execute: No such file or directory - failed to remove cgroup '/sys/fs/cgroup//lxc/test' or use a container ceated with: $ sudo lxc-create -n test No config file specified, using the default config 'test' created I used different configs and it seams it is caused by the missing rootfs. Such simple things worked in the past at least under Natty, but not in precise. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/981955 Title: lxc-execute does not seem to work in precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/981955/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 981955] Re: lxc-execute does not seem to work in precise
Ah. I see now. Thanks, guys. There are actually two things you need to add to a configuration file to make this work. If I do: cat test.conf EOF lxc.aa_profile = unconfined lxc.rootfs = / EOF lxc-execute -n test -f test.conf -- /bin/echo hi That works for me. Skipping the pinning of rootfs when lxc.rootfs = NULL would seem sensible. I'm not sure what we should do about the apparmor profile for this case. ** Changed in: lxc (Ubuntu) Status: Incomplete = Confirmed ** Summary changed: - lxc-execute does not seem to work in precise + lxc-execute without config does not seem to work in precise ** Changed in: lxc (Ubuntu) Importance: High = Low -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/981955 Title: lxc-execute without config does not seem to work in precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/981955/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 981955] Re: lxc-execute does not seem to work in precise
Thanks for reporting this bug. The output (in particular '(null)' looks strange. Is lxc installed in the container? In particular, does it have /usr/lib/lxc/lxc-init and all its dependencies installed?
