Description Roman Mohr 2016-05-20 08:07:04 UTC 
Description of problem:

In the past MOM was only responsible for ballooning. But now it also manages some CPU and storage QoS settings. When there is no ballooning device on the VM, MOM completely ignores that VM and therefore does not set QoS attributes for CPU and storage.


Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1) Create a VM with no ballooning device or with
    <memballoon model="none"/>
2) Add QoS attributes through vdsm to the domain XML metadata section


Actual results:
MOM does not apply them and writes to the logs that it ignores the VM because of no ballooning device.

Expected results:
MOM applies QoS attributes to the libvirt domain xml.

1. install mom-0.5.4-1 on the host 
2. create vm with ballooning disabled 
3. check mom logs for :
