In the Ubuntu development release we recently got a new udev that moves /var/run to /run, /var/lock to /run/lock and /dev/shm to /run/shm. This change in udev requires updating the apparmor security driver in libvirt[1]. Attached is a patch that: * adjusts src/security/virt-aa-helper.c to allow both LOCALSTATEDIR/run/libvirt/**/%s.pid and /run/libvirt/**/%s.pid. While the profile is not as precise, LOCALSTATEDIR/run/ is typically a symlink to /run/ anyway, so there is no additional access (remember that apparmor resolves symlinks, which is why this is still required even if /var/run points to /run). * adjusts example/apparmor/libvirt-qemu paths for /dev/shm [1]https://launchpad.net/bugs/810270 -- Jamie Strandboge | http://www.canonical.com
