In order to successfully use vMotion, you must first configure your hosts correctly.
Ensure that you have correctly configured your hosts in each of the following areas:
Each host must be correctly licensed for vMotion.
Each host must meet shared storage requirements for vMotion.
Each host must meet the networking requirements for vMotion.Important:
The ESXi firewall in ESXi 5.0 and later does not allow per-network filtering of vMotion traffic. Therefore, you must install rules on your external firewall to ensure that no incoming connections can be made to the vMotion socket on TCP port 8000.
