VMware ESXi problem with NIC teaming and CARP with virtual firewall/router

Very tricky one to track down why a failover firewall configuration would never promote it's CARP IP's to MASTER status.

Turns out you must only have a single NIC on a vSwitch with a guest VM being used as a MASTER for CARP, otherwise will always show as BACKUP.

Can't even have a NIC in the standby list, 2nd NIC has to be completely removed.

There may well be a setting in the advanced options somewhere that might get this to work, if anyone has done this please let us know!
