Hi Michael,Shouldn't "/sys/fs/cgroup/unified" be mounted by systemd to be used lxc to use cgroupv2? Should we need to do "mount -t tmpfs cgroup /sys/fs/cgroup" for cgroupv2 as well? Will it be done systemd ? In cgroupv1, it is usually seen "/sys/fs/cgroup" mounted on tmpfs. In case of cgroupv2 unified, nothing like that is seen. df -h Filesystem Size Used Avail Use% Mounted on udev 3.4G 0 3.4G 0% /dev tmpfs 692M 1.7M 691M 1% /run /dev/sda8 125G 57G 62G 48% / tmpfs 3.4G 0 3.4G 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock /dev/sda1 96M 62M 35M 65% /boot/efi tmpfs 692M 212K 692M 1% /run/user/1000 Please note that lxc and lxcfs is malfunctioning for fresh installs (Linux coffee 5.10.0-1-amd64 #1 SMP Debian 5.10.4-1 (2020-12-31) x86_64 GNU/Linux) as well. Not sure which package is having problem. But its(lxc) not working.
I can not confirm that. lxc is working fine here ootb with cgroupv2. No changes necessary, no manual mounts or anything.The only known issue I'm aware of, is if you want to run jessie containers on a bullseye/sid host. Since jessie's systemd does not yet support cgroupv2, you need to switch the host back to unified if you want to use such containers.
Maybe you have some custom config, which breaks lxc. The lxc maintainers will be in a better situation to help you debug that.
