Some direction for HA configuration on VM

[Lipaz]

Hello,

before i start, i would love to have links with information on how to, here are some questions i didnt found written documentation on the process.

my goal is two setup 2 VM with OPNSense and i have few question:
* if i want to add another interface, what will be the process?
* is there an option to have 2 interfaces without VIP and use them as management port?
* what is the best recommendation to monitor HA status with remote monitor platform? are the alerts send via SNMP?

thanks
