Description Israel Pinto 2017-08-16 10:41:26 UTC 
Description of problem:
While hotplug memory to VM there is mismatch of value and units in the dimm device.

Version-Release number of selected component (if applicable):
Software version:4.2.0-0.0.master.20170813134654.gitaee967b.el7.centos

How reproducible:
All the time

Steps to Reproduce:
1. Create VM with OS
2. Start VM 
3. Hotplug memory in different sizes: 256M , 512MB, 1 GB couple of time each one.
and check VM device.  
See test case: https://polarion.engineering.redhat.com/polarion/redirect/project/RHEVM3/workitem?id=RHEVM-22160

Actual results:
Memory is increased on the and update in General Tab.
But the sizes in VM device show different behavior then in 4.1.
That could expect Memory hot unplug. 
The values and units are not match with the value i hotplug.

1. Snapshot of VM devices from 4.1 with same values   
2. Snapshot of VM devices from 4.2
