Note that I *just* ran a restorecon -R -F / (for unrelated reasons: relabel onboot doesn't seem to work because / is still read-only, and that was part of the upgrade to F17), so if it's a mislabelling it's not a simple one.

In Fedora this would create a virt_lock_t. sesearch -T -s virtd_t -t var_lock_t Found 3 semantic te rules: type_transition virtd_t var_lock_t : file virt_lock_t; type_transition virtd_t var_lock_t : dir virt_lock_t; type_transition virtd_t var_lock_t : lnk_file virt_lock_t; Daniel: I may be misunderstanding where you're going there, but it sounds like you're saying this wouldn't happen on Fedora, but this *is* Fedora (F17) that I'm running, so apparently not? -Robin Added to F17.

This didn't used to happen with F16, and since it's an lnk_file issue I'm betting it's due to the directory rearrangement. "virsh console [anything]" causes: ---- type=AVC msg=audit(11/28/2012 01:58:04.878:1021) : avc: denied { read } for pid=1060 comm=libvirtd name=lock dev="dm-1" ino=393491 scontext=system_u:system_r:virtd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_lock_t:s0 tclass=lnk_file ---- type=AVC msg=audit(11/28/2012 01:58:04.878:1022) : avc: denied { read } for pid=1060 comm=libvirtd name=lock dev="dm-1" ino=393491 scontext=system_u:system_r:virtd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_lock_t:s0 tclass=lnk_file ---- type=AVC msg=audit(11/28/2012 01:58:04.879:1023) : avc: denied { read } for pid=1060 comm=libvirtd name=lock dev="dm-1" ino=393491 scontext=system_u:system_r:virtd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_lock_t:s0 tclass=lnk_file Which is problematic, since I need to do a special reboot of one of my VMs. :) -Robin
