HA with HOST & GUEST

Hi

Working on my lab environment, a doubt arises regarding the HA between VCMP Guests, and Hosts.

Currently I have a 2 hosts that contains 2 guests each one.

HA is running among the guests (ACTIVE - PASIVE), it's necessary stablish some relationship between Hosts? (ie HA Active-Active, using FAILOVER port...)

Thank you!
