Configuring a Duplicate IP Address for VMotion Causes an Error (2224)
Network addresses can be assigned to only one entity. If any addresses associated with VMotion conflict with other addresses in your network, VMotion fails.
If your environment has conflicting addresses, attempts to use VMotion might result in a VMotion-specific error, a general networking error, or a timeout.
This issue is resolved in ESX Server 3.0.1.
