   So after a lot of testing I think it is an expected behavior due to the 
design.
   
   I have the issue regardless distro, I', using ubuntu 22.04 for example.
   
   Long story short, the HA mechanism won't work at all when the server is 
powered off or IPMI is unknown that will happen when the server has no power at 
all.
   
   The odd thing is that the coordination between HA Host and HA VM, if would 
be better would overcome the problem. I ended up ignoring the HA Host all 
together and keep using HA VM, that works, it has a caveat that takes around 15 
minutes to trigger , but eventually does, after breaching the threshold 
acceptable of having lost NFS heartbeat.
   
   I have no idea where to manipulate that timer, been trying to look at it, 
but I have bigger fish to fry at this point so I'm accepting that in a rare 
circumstance when a host is powered off or looses environmental power it will 
take +/- 15 minutes for the vm to bounce elsewhere.
   
   So the workaround for me is simply disable Host HA in the cluster/zone/host 
and be patient when requires an HA.
   
   There are enough things in place to make the mechanism robust is just the 
coordination between the 2 mechanisms requires some work. But a feature request 
needs to be raised. I don't consider this a bug, rather a design flaw.
