MOM policy

Description of problem:

When VM has minimal system with no apps running, MOM will decrease memory via balloon mechanism until out of memory panic. There is no minimal memory value defined in policy.

Version-Release number of selected component (if applicable):
mom-0.3.0-1.el6.noarch

How reproducible:
Install  centos 6.3 minimal on VM, configure VM for MOM, run MOM on host and wait until VM panic.
Comment 1 Martin Sivák 2013-10-11 09:01:02 UTC 
Can you please retest with more recent version of MoM? 0.3.0 is very old and there were many bugs fixed in 0.3.2. Minimal guaranteed memory for a VM was added to that version as well.

Also can you please attach more information about the host and the VM? Especially memory information (output of free and the VM's domain XML) is important for debugging this.

I get latest MOM from git repo and I saw that rules policy has changed. Now they're working like I expected. Thanks.
