Troubleshooting migration compatibility warning: The VMotion interface of the destination host uses network, which differs from the network used by the VMotion interface of the source host

Symptoms


  • When performing a VMotion migration the following compatibility warning is displayed:

    Unable to migrate from <source server> to <destination server>: Currently connected network interface '<device>' uses network '<network>', which is configured for different offload or security policies on the destination host than on the source host .

Resolution

Overview

This unable to migrate warning indicates that the Network Label of the VMkernel portgroup, used for VMotion between the ESX Servers is different.
 
Note: The compatibility check only verifies that the network names of the portgroups to ensure that the network is the same, it does not check connectivity.
 
This warning can be safely ignored as long as the VMkernel portgroups used for VMotion are connected to the correct physical network.
 

Workaround

To workaround this issue, edit the settings of the virtual switches on your ESX Servers that have the VMkernel portgroup configured. Change the Network Label to be exactly the same between the ESX Servers that participate in the VMotion.
