[pkg-lxc-devel] Bug#961578: lxc-tests: fails in autopkgtest-virt-qemu of cgroup2 / unified hierachy

[Ryutaroh Matsumoto]

Package: lxc-tests
Version: 1:4.0.2-1
Severity: minor
User: pkg-systemd-maintainers at lists.alioth.debian.org
Usertags: cgroupv2

Add "systemd.unified_cgroup_hierarchy=1" to /etc/default/grub
in a QEMU testbed created by autopkgtest-build-qemu, and run
update-grub in it.
Then autopkgtest -B -o some-directory lxc -- qemu /var/lib/libvirt/images/sid-cgroup2-ext4.img shows

FAIL: lxc-tests: /usr/bin/lxc-test-cgpath
---
cgpath.c:73 lxc_cmd_get_cgroup_path returned NULL

It seems a non-essential symptom, though.

Best regards, Ryutaroh Matsumoto
