Would it be possible to have overlay and aufs build as modules? I know it's probably not recommended, but I run docker in a container with 5.4 and it works well for me. With the 5.11 kernel, these modules don't appear to be build in a way modprobe can find.We just uploaded a 5.11 kernel into our pvetest repository. The 5.4 kernel is still the default on Proxmox VE 6.x series, 5.11 is an option.
How to install:
Feedback is welcome!
- enable the pvetest repository (pvetest is not recommended for production setups)
- apt install pve-kernel-5.11
- reboot
