Just a quick FYI on a new Knowledge Base article we published today. This one talks about an issue where an attempt to perform a live migration on non-clustered virtual machines (shared nothing live migration) from one host to another will show a zero rating for the desired host and display the following text in the Rating Explanation field:
Migration check for virtual machine <serverName> failed to create a planned virtual machine in the target host. Detailed error message: The Virtual Machine Management Service failed to establish a connection for a Virtual Machine migration with host serverName.contoso.com: No connection could be made because the target machine actively refused it. (Ox8007274D).
