Doc Type: Bug Fix
Doc Text:
Cause: Comparison of memory values stored as string and integer. Consequence: hosted-engine-setup proposes as a default to use all the available RAM for the engine VM also if bigger than the value in the appliance OVF. Fix: Always convert memory values to integer before using for comparisons. Result: hosted-engine-setup proposes reasonable values of memory.

Description Simone Tiraboschi 2016-01-20 10:44:23 UTC 
Description of problem:
hosted-engine setup proposes as a default to use all the available RAM for the engine VM also if bigger than the value in the appliance OVF.

Example:
256 GB host, 16 GB recommended in the engine-appliance OVF:
Please specify the memory size of the VM in MB [Defaults to maximum available: 255067]: 


Version-Release number of selected component (if applicable):
1.3.2.2

How reproducible:
100%

Steps to Reproduce:
1. hosted-engine --deploy on a system with more than 16GB of RAM
2.
3.

Actual results:
Please specify the memory size of the VM in MB [Defaults to maximum available: 255067]: 

Expected results:
Please specify the memory size of the VM in MB [Defaults to appliance OVF value: 16384]: 

Additional info:

Probably is the result of a string vs integer comparison.
Please ensure that we are always handling it as an integer (also if the user enters a custom value and we gather it via dialog.queryEnvKey )
