Environment

VMware vCenter Server 7.0.x
VMware vCenter Server 6.7.x
VMware vCenter Server 6.5.x

Cause

This failure occurs when port TCP 902 is blocked between the source host and the destination host.

Note that cold migrations are considered provisioning traffic and by default go over the management interface. However, if a dedicated provisioning vmkernel interface is configured, it will use this instead.

Resolution

To correct this issue, remove the firewall rule or network block which is stopping TCP 902 traffic between the hosts.
