------------------------------------------------------------------
Spent a bit more time on this:
1. I verified the agent is 4.3.0-1.el6 (from Yum list). Management Server is
too.
2. I verified that 'vm.memballoon.disable=true' is in the agent.parameters file.
3. I restarted VMs on more than one host, many times. It always shows
<memballoon model='none' ><alias name='balloon0'/>.
I was however able to set the memory over provision factor to 2 (in the Cluster
settings), coupled with creating a custom system offering with 512MB RAM for
the Virtual Router; this allows the router to restart without a problem.
Over provisioning however is an important feature and would like to get to the
bottom of this. I did notice that issue 5968 references that the code update
for this issue was for 4.4.0. Is it possible the code I am running just does
not include this feature?

>
> This is issue is reproducable when setting the cluster property

> greater than one, the Virtual Router VM is created on the host, but never
> boots.
