vMotion compatibility fails with error: "The vMotion interface is not configured (or is misconfigured) on the destination host"

Products

• VMware vCenter Server

Issue/Introduction

• When performing a vMotion migration, you see the compatibility error:

  Unable to migrate from source_server to destination_server: The vMotion interface is not configured (or is misconfigured) on the destination host 'destination_server'.

Environment

• VMware vCenter Server 8.x
• VMware vCenter Server 7.x

Cause

The VMkernel port group used for vMotion is not configured or misconfigured on the source/destination ESXi server.

• To vMotion between ESXi hosts, a VMkernel port with a unique IP address is required on each of the ESXi host systems.
  See, What Are the vSphere vMotion Networking Requirements
• The error may occur if the VMkernel port group is not configured properly, uses a duplicate IP address, or has a subnet misconfiguration.

Resolution

To resolve the issue, review the configuration of the VMkernel adapter that is being used for vMotion using the steps below:

1. Log in to the vCenter server using the vSphere client as an administrator or with equivalent credentials.
2. Select the ESXi host from the inventory.
3. Select the Configure tab.
4. Under the Networking tab, select VMkernel adapters.
5. Select the VMkernel adapter and choose the Properties tab. For more details, see Place vMotion Traffic on the vMotion TCP/IP Stack of an ESXi Host
6. Ensure that the VMkenel adpater IP address is configured correctly and vMotion isenabled on the portgroup.
7. Also, validate round trip time between the vMotion VMkernel adapters across hosts. The maximum supported network round-trip time for vMotion migrations is 150 milliseconds. This round-trip time lets you migrate virtual machines to another geographical location at a longer distance.
