Using cgroup?

[rclobus]

Hello,

in the file worker-log.txt (e.g. https://openqa.opensuse.org/tests/4860088/logfile?filename=worker-log.txt) the following entries occur:

[info] Preparing cgroup to start isotovideo
[warn] Disabling cgroup usage because cgroup creation failed: mkdir /sys/fs/cgroup/systemd: Permission denied at /usr/lib/perl5/vendor_perl/5.26.1/Mojo/File.pm line 85.
[info] You can define a custom slice with OPENQA_CGROUP_SLICE or indicating the base mount with MOJO_CGROUP_FS.

Should openQA have used a cgroup? I could not find the word 'cgroup' in the documentation (http://open.qa/docs/)

Well, there is no high-level documentation as this is merely an implementation detail in the openQA worker, see https://github.com/search?q=repo%3Aos-autoinst%2FopenQA%20cgroup&type=code
