Description of problem: Continuously getting the Error message in vm.log file from qemu/kvm libust[121880/121886]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:886) Version-Release number of selected component (if applicable): rpm -qa |grep ceph ceph-common-0.94.5-4.el7cp.x86_64 ceph-osd-0.94.5-4.el7cp.x86_64 ceph-0.94.5-4.el7cp.x86_64 ceph-radosgw-0.94.5-4.el7cp.x86_64 ceph-debuginfo-0.94.5-4.el7cp.x86_64 ceph-selinux-0.94.5-4.el7cp.x86_64 selinux: Loaded policy name: targeted How reproducible: Always Steps to Reproduce: 1. Create a RBD image, take snap and clone it. 2. Attach the same image in Qemu. 3. Create a VM on top of that RBD clone image. 4. Do some write operations of that image. Actual results: Seeing lots of Error in log message of the VM Expected results: There should not be any Error log message.

We missed some selinux patches (bz 1304455). They will be in the next spin.
Marking it verified. As i do not see any further error logs from my VM.log libust[121880/121886]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:886) Ceph Build: ceph-common-0.94.5-9.el7cp.x86_64 ceph-selinux-0.94.5-9.el7cp.x86_64 ceph-0.94.5-9.el7cp.x86_64 ceph-osd-0.94.5-9.el7cp.x86_64
