Upon a container's start/stop the following message can be seen in
/var/log/messages on the PVC node:
Nov 16 23:17:58 hwnode kernel: [121067.626045] VE13: no allowed mount options found for device 0:155 Nov 16 23:24:10 hwnode kernel: [121440.030931] VE15: no allowed mount options found for device 0:164
The messages are informative in nature and mean that vz service does not have a list of options that can be used when mounting the container's filesystem.
This message has been introduced in 079.x kernels.
Such messages do not indicate any problems and can be ignored.
