NFS in Container

NFS requires extra permissions to run in a Container (CT), which uses LXC.

Deselect "Unprivileged container", and add the Features "mount=nfs"

# mount 192.168.108.30:/nfs/ken /mnt
mount.nfs: access denied by server while mounting 192.168.108.30:/nfs/ken

When trying to add the "mount=nfs" feature:

Permission check failed (changing feature flags for privileged container is only allowed for root@pam) (403)

Login as root and:

pct set 112 -features mount=nfs

# pct set 112 -features mount=nfs --save  # is this needed?

LXC - Linux Containers

To use the LC options you first need to download a LC template.

First update the list:

pveam update

Note: The list of available templates is updated daily through the pve-daily-update timer

To list images:

pveam available

To list only system images:

pveam available --section system
