VMware HA with VM Monitoring doesn't reboot my VM after I shut down the VMware tools on it

Hi,

Currently, we are testing the VMwware HA with our product. I enabled the VM monitoring on our cluster.

Inside the clusters, we have 3 Ubuntu 8 (console only) VMs.  I manually turned down the VMware tools in it by calling open-vm-tools stop.

I checked from the mob page of VC, the guestHeartbeatStatus of that VM is "red". however, vSphere still don't want to reboot my VM as I expected.

Any idea how actually the VM Monitoring works?

So I tried turn off my VM compeletedly from Ubuntu console, should VM monitoring turn my VM back on? How can VMware HA tell whether the VM is supposed to be on or off?

Thanks,

Ben

The following blog post may explain this (VM HA)

from http://www.yellow-bricks.com/2010/06/04/vm-monitoring-aka-vm-ha-heartbeat/

One thing to keep in mind though is that when heartbeats are no longer  received, by default sent out every second, VM Monitoring will check if  there is any Network or Storage I/O to avoid false positives.
