Prepare the container
To allow a container to use NFS filesystem, you will need to start it with “nfs” feature enabled. If the container is running while you set the –features nfs:on, you will need to reboot it.
# vzctl set 101 --features "nfs:on" --save # vzctl start 101
After this you may see nfs in /proc/filesystems
# vzctl exec 101 cat /proc/filesystems ext3 ext2 nodev rpc_pipefs nodev proc nodev nfs nodev sysfs nodev tmpfs nodev devpts
