Hello OpenVZ community, Recently I identified a package called "ctpreset" on a new container created, installed from here [1], and after looking into the .deb's content, I found that it overrides some systemd configs (copied below) every Monday at 01:00.
The overrides are: [Manager] DefaultCPUAccounting=no DefaultIOAccounting=no DefaultIPAccounting=no DefaultBlockIOAccounting=no DefaultMemoryAccounting=no DefaultTasksAccounting=no DefaultTasksMax=infinity Continuing the research, I found that Systemd started enabling those flags from kernel 4.15 and newer [2] and it's interesting to see that if we would like to disable such resource accounting, we would need to regularly "fight" the systemd config. >From a performance perspective, I see such measures as positive, considering that OpenVZ itself already does the resource accounting for the container. I would like to know your opinion :) Paulo Coghi [1] https://repo.virtuozzo.com/ctpreset/deb/ [2] https://www.freedesktop.org/software/systemd/man/systemd-system.conf.html
