When snapping a VM, an error message states "Invalid Virtual Machine Configuration" and the snap fails. The snap works when the VM is VMotioned to another host.

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:

Host1
Host2

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?

Is this happenning to all VMs or specific VM? Did you check the esx/vm log files?

This is happening across the board. The VM logs report the same error "Invalid Virtual Machine Configuration". My current work around is to migrate the machine from the host and everything works. I also found that I cannot Edit the VM settings unless I migrate the machine as well. It looks like once the VM is migrated the error is permanently fixed. It must have something to do with the new patches needing the VMs to re-register with the hosts, I'm guessing.
