This bug is not fully solved by this version, because the init job still tries to load and unload kvm modules.

Re: [Bug 1078530] Re: upstart job fails to start under lxc
Well, its hard to run the openstack test suite in a container *without* qemu-kvm, because python-libvirt depends on libvirt depends on qemu-kvm. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1078530 Title: upstart job fails to start under lxc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1078530/+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 1078530] Re: upstart job fails to start under lxc
@lifeless, the upstart job is only responsible for setting up the kvm kernel module and related kernel settings. With my new proposed change, the upstart job would detect it's in a container and consider itself done. In reality, for quantal the modprobes and rmmods were already doing '|| true'. So the only thing my new upload changes is that rather than try to do all these things and be denied, it won't try. (Or, rather than try to do them and succeed due to a bad policy, and potentially break the host.) The host will have to set up kvm; but it would have to anyway, since containers are never allowed to modprobe by default. And quantal and later always modprobe kvm on the host. Finally, libvirt and python-libvirt do not depend on qemu-kvm. But again, qemu-kvm will install just fine and even be usable in the container. It just can't be set up there. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1078530 Title: upstart job fails to start under lxc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1078530/+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 1078530] Re: upstart job fails to start under lxc
Regarding this being a bug in lxc as well, the failure to write under /sys is deliberately enforced by the apparmor policy. It can be worked around by using another apparmor profile (or none, as commented in the configuration file), but is not recommended - containers should not change kernel settings. ** Also affects: qemu-kvm (Ubuntu Precise) Importance: Undecided Status: New ** Also affects: qemu-kvm (Ubuntu Quantal) Importance: Undecided Status: New ** Description changed: The KSM_ENABLED setting (on by default) for the qemu-kvm job fails under lxc but the kernel files still appear writable. Thats likely an lxc bug (either in defaults or device mapping), but there is no need for qemu- kvm's job to fail if those settings can't be written to IMNSHO. + + + SRU Justification: + 1. Impact: qemu-kvm cannot be installed in containers + 2. Development fix: ignore errors writing under /sys in upstart job + 3. Stable fix: same as development fix + 4. Test case: + sudo lxc-create -t ubuntu -n c1 -- -r [precise|quantal] + sudo lxc-start -n c1 + # log into c1 as ubuntu/ubuntu, and 'sudo apt-get install qemu-kvm' + 5.
