vMotion resource maps provide a visual representation of hosts, datastores, and networks associated with the selected virtual machine.

vMotion resource maps also indicate which hosts in the virtual machine’s cluster or datacenter are compatible with the virtual machine and are potential migration targets. For a host to be compatible, it must meet the following criteria.

Connect to all the same datastores as the virtual machine.

Connect to all the same networks as the virtual machine.

Have compatible software with the virtual machine.

Have a compatible CPU with the virtual machine.


The vMotion map provides information as to whether vMotion might be possible, and if not, what an administrator might do to remedy the situation. It does not guarantee that a particular vMotion migration will be successful.

Hosts marked with a red X are unsuitable candidates for migration. A lack of edges connecting that host and the virtual machine's networks and datastores indicate that the host is unsuitable because of networking or datastore incompatibility. If the unsuitability is because of CPU or software incompatibility, the information appears in a tooltip when the pointer hovers over the host in question.

It might take a few seconds for the map to retrieve load, CPU, and software information. The state of the map's information retrieval process appears in the lower-left corner of the map. As information arrives, the map is updated. A host that looks like a good vMotion candidate (displayed as green) might become a bad candidate (displayed as red) as information is collected.
