LXC and qcow2

[Alexandr]

Hello!

Does LXC container support qcow2 disk? How I can create it?
Because I need creating live snapshot and I have to have dynamic size disk


Thanks!

Did work with Ceph and ZFS Storageformat.

NO

Use as Fireon suggest ZFS or Ceph.
Also LVM-Thin is a option.

Hi,

With RBD (i used external Ceph cluster) discard not working, so thin provision will be unavailable basically.

Hi all, I am setting up a proxmox cluster with GlusterFS. Is there a viable way to create LXCs as qcow2 instead of raw and use the snapshot functionality? Thanks and greetings, Thorsten

Proxmox VE does not natively support (rootdir is missing in the content types list of the respective wiki page) LXC on GlusterFS. You can workaround by creating a directory storage on your GlusterFS storage.

Nevertheless, it is still not possible to use qcow2 as LXC rootfs.

@Dominic:
Somebody find a solution: https://www.howtoforge.com/tutorial/how-to-setup-virtual-containers-with-lxc-and-quota/ Maybe, your team give it a try. that would be awsome, when proxmox woult support this. I see the mass of fans growing.
