Does Proxmox support LXC dir backend ?

[yreveillon.ext]

Hi,

With LXC, I can have :
Host : /data/vm/rootfs
And the LXC VM boot on /data/vm/rootfs, which is a simple directory on the host.

How to do the same thing under Promox ?
I can create a raw file to become the rootfs then add with :
pct set <id> -mp0 /data/vm/rootfs/home,mp=/home,backup=0

But how to make this for the root VM ?

In LXC config, this is do with :
lxc.rootfs.path = dir:/data/vm/rootfs

Thanks

Hi,
Lxc and lxc in proxmox are two really differents thinks: most of options and commands are modified in Proxmox environment. But you can tey to puah manually yours tips directly in container configuration file located /etc/pve/lxc/

the first question would be why you want to do that you can access a container's file using 'pct mount' and 'pct pull'/'pct push', so it's usually better to use real volumes and all the advantages that gives you over a plain directory.

that being said, there are two options:
- use ZFS, where containers use datasets, which are only bind-mounted into the container and exist as mounted datasets on the hypervisor host
- use --rootfs STORAGE:0,size=0 where STORAGE is the ID of your directory storage - this will allocate a directory instead of an image file, but won't support snapshots and other things
