LXC on cgroup v2 seems to have no problem with Debian CI. Autopkgtest on systemd gave no error as below. Specifically, related Debian package versions are: $ grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0 $ dpkg-query -W | grep lxc liblxc1:amd64 1:4.0.2-1~1 lxc 1:4.0.2-1~1 lxc-templates 3.0.4-3 /etc/lxc/default.conf is lxc.apparmor.profile = generated lxc.apparmor.allow_nesting = 1 # The above lines are the Debian package default. lxc.net.0.type = veth lxc.net.0.link = lxcbr0 lxc.net.0.flags = up #lxc.mount.auto = cgroup:rw:force lxc.init.cmd = /sbin/init systemd.unified_cgroup_hierarchy=1 Under the above setup, I ran # debci setup and $ autopkgtest --user debci -o /var/tmp/outdir systemd -- lxc --sudo autopkgtest-unstable-amd64 The result was autopkgtest [17:43:14]: @@@@@@@@@@@@@@@@@@@@ summary storage SKIP Test requires machine-level isolation but testbed does not provide that upstream SKIP Test requires machine-level isolation but testbed does not provide that systemd-fsckd SKIP Test requires machine-level isolation but testbed does not provide that timedated PASS hostnamed PASS localed-locale PASS localed-x11-keymap PASS logind PASS unit-config PASS networkd-test.py PASS build-login PASS boot-and-services PASS udev PASS root-unittests PASS boot-smoke PASS Best regards, Ryutaroh Matsumoto
