This is in Openstack installation. When trying to snapshot a instance I see the
following in libvirt.log
2017-07-26 09:27:12.129+0000: 46621: warning : AppArmorSetFDLabel:982 : could
not find path for descriptor /proc/self/fd/38, skipping
2017-07-26 09:27:12.131+0000: 46621: error : qemuMonitorJSONCheckError:382 :
internal error: unable to execute QEMU command 'migrate': Migration disabled:
failed to allocate shared memory
In nova-compute.log I see:
2017-07-26 11:27:13.038 171589 ERROR oslo_messaging.rpc.dispatcher
libvirtError: internal error: unable to execute QEMU command 'migrate':
Migration disabled: failed to allocate shared memory
I apply this patch to /etc/apparmor.dabstractions/libvirt-qemu and everything
works:
