We have a brand new built cluster on Server 2019. After the initial configuration live migration was working flawlessly. Now all of a sudden we're running into issues with Live Migration. I've narrowed it down to only Configuration Version 9.0 machines. There are a handful of configuration version 5.0 machines from our old cluster that we've migrated over and they still are able to Live Migrate without any issues. We can still quick migrate the version 9.0 machines. The only thing that was recently done was that the machines all had storage migrated to another CSV and back to the original one so we could rename it. I've attempted moving one 9.0 machine to the new CSV and still have the same issues. I've even upgraded previously working 5.0 machine to 9.0 and it immediately starting having the same issues.
The error that is listed is simply: Live migration of 'Virtual Machine Hostname' failed.
