This issue occurs when the Network Label of the VMkernel portgroup used for VMotion differs between ESX hosts.

This warning can be safely ignored as long as the VMkernel portgroups used for VMotion are connected to the correct physical network.

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.

To eliminate the warning completely:

1. Edit the settings of the virtual switches on ESX hosts that have the VMkernel portgroup configured.
2. Change the Network Label to be same (including case sensitivity) across ESX hosts involved in the VMotion.
