4.2 Test failed -  HA does not work on KVM Hypervisor

Hello,
I ask for assistance.
We try several installation of CS4.2 on different hardware.
HA does not work neither for Virtual Router nor Virtual Machine with HA
enable compute offering.
We test configuration with 2 KVM hypervisor.

Hello Rendy,
thank you for you answer.
As I know it have to be featured in version 4.2. The issue what you 
describes,
related to version 4.0 and 4.1. There was not KVM host investigator but for
now the problem is not to find out which host is down - it's functions,
the problem is that stopped VM doesn’t start automatically on available 
resources, it stays in stopped state and you have to turn it on 
manually, virtual router too.
In general I don't understand why there is not function to set host down 
manual or via api.
The admin or external monitoring system could mark host as down and send 
the command to management to start VM's on available host.

as far as I know this is known bug(feature :D)

fro what I read about it, it was disabled at one point when they realized
that there isn't a solid way to prevent split brain on KVM hosts.
HA works for ESX and Xen servers I think. If you search a little bit,
you'll find how to enable the HA forcibly.
