how do you setup a Cluster VM of say Home Assistant. on 2 Unraid machines?

id like to run a cluster i guess thats when 1 computer is down it bounces to the 2nd computer

so i wanna run  to practice with my Home Assistant.. on my Tower Unraid and my Backup Unraid

so when my Main Unraid is shut down..  it goes to backup  Unraid with the same name address 

how do you do that to link 2 VMs together  and do that 

and is that what a cluster is ?  so when main is off the backup takes over

as id like to do it for my websever vm too but i figured try with home assistant first 

if there is a video or explantion like a guide.. maybe someone can post that
