When snapping a VM with snapshot manager, I get an error message stating Invalid Virtual Machine Configuration. When I VMotion the VM to another host I am able to successfully snap the VM. The snapshots failures are not host specific - meaning the snapshot could fail on one host, VMotion to another host and it works. If I move a VM to the original host with the failure there is no configuration error. For example:
VM1 is on host1. I try to snap it and get the failure. I VMotion the VM to host 2, and it works.
VM2 is on host2. I try to snap it and get the failure. I VMotion the VM to host 1 and it works, but I originally got the error on host1 with VM1.
What could this possibly be?
