Post Escalation Review

VMware Support has developed a Post Escalation Review process. We review critical escalations which come into our Escalation management team and determine steps to prevent these escalations in the future with other customers. One of the outcomes of this process is the creation of Skyline Findings.

In KB 83530, GS Escalation where customer was unable to complete their ESXi upgrade to 6.7 as when they attempt to vMotion to an ESXi 6.7 host, the host starts to “slow down” when there are more than 130 VMs on it, the larger the number of running VMs on it, the slower vMotion proceeds, until a certain moment vMotion is not possible anymore and results in a general error during the vMotion process.

  • vSphere-VmotionFailure-KB#83530
    • Description: vMotion to 6.7 host that has too many VMs is extremely slow and usually fails at 18%
    • Resolution: This issue is resolved in VMware ESXi 6.7 Patch 06 (build number 18828794)
