Description Lukas Svaty 2014-10-15 10:45:31 UTC 
Description of problem:
Balloon on VM is re-enabled with every API call.

Version-Release number of selected component (if applicable):
vt5

How reproducible:
100%

Steps to Reproduce:
1. Add VM
2. Edit VM -> Resource Allocation -> Uncheck 'Memory Balloon Device Enabled'
3. Edit VM name via REST or other API

curl -X PUT -H "Accept: application/xml" -H "Content-Type: application/xml" -u admin@internal:$pwd --cacert ca.crt -d "<vm><name>foo</name></vm>" https://$engine/api/vms/$vmID


Actual results:
VM is re-enabled on VM.

Expected results:
All the settings of VM should stay as before REST API call edit except for name.

Additional info:
The same behaviour via rhevm-shell.
This fix should be backported to rhevm 3.4 as it is causing huge problems with ppc where ballooning is not supported.
Comment 1 Juan Hernández 2014-10-16 08:59:07 UTC 
Whatever the solution to this issue is, please try to make sure that there is no business logic inside the RESTAPI.
Comment 3 Michal Skrivanek 2014-10-22 14:33:37 UTC 
so is this reproducible on 3.4.z engine?
Comment 4 Lukas Svaty 2014-10-22 14:40:22 UTC 
yes, 

WA for this is to add to every API CALL

<ballooning>false<ballooning>

In case this is missing in the API call balloon will be reenabled
