Server CPU utilization very high after vMotion event.

Solution Verified - Updated -


  • We have a system running RHEL 5.6 as a VMware guest on an ESX server.
  • There was a vMotion event that moved the guest operating system to a different server in the VMware cluster and since then the CPU utilization is maxed out with very high user / system time.
  • System CPU usage and load on RHEL 6 VMware guest is very high during vMotion which causes network connections to drop. This high load persists until the guest is rebooted.
