[systemd-devel] CPU usage limit to systemd-nspawn container is not working

[patlollamahipal at yahoo.co.in]

Hi Colin,
Yes missing . was just a typo. I tried override.conf in /etc/systemd/system/systemd-nspawn at appscont.service.d/, still I do not see any change in CPU utilization.
Container processes(sh and sha1sum)  are using 50% CPU irrespective of CPUQuota in  ExecStart=/usr/bin/systemd-nspawn --quiet --boot --link-journal=try-guest --machine=%i -n --property=CPUQuota=5% 
I tried CPUQuota=5% under service section in override.conf instead of ExecStart, still the CPU usage is 50%
And also I tried both in ExecStart as well as separate entry of CPUQuota=5% under service section after ExecStart, still the CPU usage is 50%
Attached the systemd-cgls output for machine.slice.


Regards
Mahipal

I think you missed a . above:
/etc/systemd/system/systemd-nspawn at .service.d/*

there is no system.control folder.

You should place a file called override.conf (or anything.conf) in a
folder: /etc/systemd/system/systemd-nspawn at appscont.service.d/ if you
want the overrides defined in the .conf file to only apply to that one
machine.

All the best and HTHs
