GitHub user DaanHoogland added a comment to the discussion: How is KVM HA 
expected to work (HW without IPMI)

KVM HA is a bit confuring but you might be right. That said, one cannot expect 
ACS to be sure if a VM is down if the host is not fenced and a power report 
from the host shows the VM as down. There is an expectation that a host being 
down is taken for a fact by ACS, but that can lead to split brain scenarios and 
consequently to data loss.

@zidz , KVM HA is not a term that is used in cloudstack, can you clarify your 
expectations? (so we can assess better if these are realistic ;)
