This virtual machine failed to become vSphere HA Protected and HA may not attempt to restart it after a failure.

Hello EE,

Wanted to run this past you all to see what route would be best to take. Newer VMs being brought online in our vSphere (6.5 Update 1) are reporting:

This virtual machine failed to become vSphere HA Protected and HA may not attempt to restart it after a failure.

https://kb.vmware.com/s/article/2020082

From what I can gather my impression here is that maybe this could be;

1. A cosmetic in vSphere where  it is reported wrong, where disable and re-enable HA could resolve.
2. Not enough resources on other hosts for these new VMs to stay online in the event of a host down issue.

I am leaning towards #2 for our environment and just wanted to check with EE and see how you would best approach resolve for this?

Thank you for any feedback.

This can often happen, if you power cycle the VM, and clear the alert, does the Unprotected status disappear, and become protected.
