This issue affects switch extension users only (mostly Cisco-based) when almost all the ports on a switch extension or a port profile are being used.
- Increase the maximum number of available ports on switch extensions and port profiles. There should be at least one available port for each virtual machine.
- Manually live-migrate virtual machines that are using switch extensions. Do this one virtual machine at a time before you put the host into maintenance mode.
