How to restore systemd-sysctl.service and systemd-vconsole-setup services to start on Centos 7?

Question

linux

centos-7-amd64 is on VDS (OpenVZ). I enter systemctl list-units, I see this nonsense:

* systemd-sysctl.service loaded failed failed Apply Kernel Variables
* systemd-vconsole-setup.service loaded failed failed Setup Virtual Console

I'm trying to run them manually:

[[email protected] ~]# service systemd-vconsole-setup start
Redirecting to /bin/systemctl start systemd-vconsole-setup.service
Job for systemd-vconsole-setup.service failed because the control process exited with error code. See "systemctl status systemd-vconsole-setup.service" and "journalctl -xe" for details.
[[email protected] ~]# service systemd-vconsole-setup status
Redirecting to /bin/systemctl status systemd-vconsole-setup.service

What are these bugs and how to fix them?

Answer 1

It's about openvz. The technology does not allow changing the kernel parameters from the container.
