After moving a VM from one VM Server to another, it has been the case always that for at least 4 hours after the CPU hits 100%, and then goes back to normality.

Is there a reconfiguration process running in the background?

HOST: W2K3, 4GB RAM, RAID 5, 300GB 15K RPM, etc
VM: W2K3, 3GB RAM, 12OGB, etc

No services. Just as a VM Server.

The CPU increase happens always for the first 4-5 hours after I moved a VM from one VM Host to another.

...the usual, none of the ones listed are allocating that CPU continuous spike

Note: it's the VM that hits 100% CPU, not the VM Host

  1. Is the cpu peeking in both the VM and the host?
  2. How many virtual cpus have been given to the VM and how many cores in the host?
  3. What antivirus software?
  4. Is VMware Tools installed?
  5. Tried following these steps?
