Systems runs but not... reboot not possible sometimes (KVM)

Hello all,

i running here ucs 4.4-2 errata328. The VM’s running on Proxmox6. VM’s installed with UEFI. So sometimes (about every 3-4 weeks) CheckMK show an error that all checks can’t be checked anymore. But the machine is running, all services working.

What is not working?

  • Systemctl
  • journalctl
  • reboot

Errormessage:

Failed to open /dev/initctl: Kein passendes Gerät bzw. keine passende Adresse gefunden
Failed to talk to init daemon.

What helped (but not fine) is force:

root@dc1:~# reboot -f
Failed to read reboot parameter file: Datei oder Verzeichnis nicht gefunden
Rebooting.
packet_write_wait: Connection to 2001:460:1e0c:547::1 port 22: Broken pipe

What can i do to solve the problem?

Very Thanks
