I installed all the binary packages from https://launchpad.net/ubuntu/+source/libvirt/1.2.2-0ubuntu13.1.3 , then enabled trusty-proposed repository and did a dist-upgrade from there, then rebooted.
But still I am getting this error when trying to start a libvirt domain using vfio: error: internal error: Process exited prior to exec: libvirt: error : cannot limit locked memory to 3221225472: Operation not permitted -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1276719 Title: apparmor denies VFIO passthrough: RLIMIT_MEMLOCK and /dev/vfio/XX To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1276719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
