The VM is a Windows based VM, the latest tools were downloaded and installed on the same day as this post.

It is moving from a Ryzen 5900X host to another Ryzen 5900X host.

It is using shared storage (NFS Share).

I really wish the error message would specify what feature is lacking as it would help me troubleshoot this much easier.

Hi,

This means the VM isn't cooperating. The most likely thing is an issue regarding the tools, not correctly installed or working.

@olivierlambert
I would have thought that too... except it does it for every VM

At this stage I am just going to rebuild the pool and migrate the VM's and other hosts across to it instead.
