I have recently updated to the latest version of Proxmox, after which it appears that nested virtualisation no longer works. I noticed this because after the update reboot, docker, which is hosted in a privileged CT, can no longer run any containers.
What ive tried so far:
- Ive tried updating to the test kernel thinking the problem may be related to a kernel update.
- Ive created a fresh CT and attempted to run a docker container with no luck.
- Ive double checked my configs, iommu and the like but nothing has changed.

cat /sys/module/kvm_intel/parameters/nested
is Y.Any ideas? What should I be looking at to diagnose this further?
