By default, Hyper-V hosts use Kerberos to communicate with each other securely. If you ever want to migrate a VM from Host2 to Host3, you have to give Host2 delegated permissions to communicate with Host3. The above link explains how to enable that. Basically, you open the source host in ADUaC, add delegated cifs and microsoft migration service permissions to it. You may as well do this from every Hyper-V host to every Hyper-V host, which can take a long time if you have many of these hosts.
