restore lxc with overlay2 docker images in it

[andrew sp]

Hi, recently i've added overlay2 module to proxmox-host, so i can easily use basic docker-cli functionality inside an lxc containers (pull/tag/push), without using runtime.
But attempt to restore a container with overlay2 layers (docker images) inside fails:

is there anything i can do with it?

hi,

try restoring it as privileged container (you will see a checkbox in the restore operation)
