Best approach to share host FS to VM, NFS direct or NFS via LXC?

[Rxunique]

I just went through a journey trying to share ZFS dataset to VMs rather than mount it as Hard Disk.

The goal is to have files accessible without VM running.

I see it beneficial dealing with large files stored on spinning rust, such as surveillance videos or photo gallery.

It's quite simple to get Samba working with Windows VM, there are several youtube walk through.

But to get NFS via LXC, it's a deep rabbit hole, needing privileged LXC and permission edit

All these extra steps and bypassing security makes NFS via LXC feels counter-productive, might as well just run NFS on proxmox direct.

Is it a bad idea to run NFS direct on proxmox? Privileged LXC doesn't seems to be much better here

Is there any other alternative to mount host FS to VM in proxmox?

Virtiofsd to share host directory directly to vm.

Virtiofs sounds promising, thanks a lot

Found another detailed write up here https://gist.github.com/Drallas/7e4a6f6f36610eeb0bbb5d011c8ca0be

Too bad Virtiofs doesn't support migration yet
