Allow NFS attachment on Proxmox OpenVZ containers

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
