Increased CPU usage and Server load in idle?

I noticed a strange behaviour my Proxmox (VE 8.0.3). CPU usage and load jumps after a few days and stays there.

  • just 2 VMs installed -> their CPU usage is unchanged
  • nothing else / running or changed


Looking at the running processes I can just find ksmd with high usage:

The 2 VMs running:

I restarted the server and both VMs and will monitor the load ... after reboot back to "normal idle".
