Doc Type: Enhancement
Doc Text:
This release adds the ability to specify a Maximum Memory value in all VM-like dialogs (Virtual Machine, Template, Pool, and Instance Type). It is accessible in the `{vm, template, instance_type}/memory_policy/max` tag in the REST API. The value defines the upper limit to which memory hot plug can be performed. The default value is 4x memory size.

Description jniederm 2016-10-24 20:28:29 UTC 
Allow to configure maximum memory size per VM. The value should default to 4x memory size.

Currently max mem size is set by global config values VM32BitMaxMemorySizeInMB, VM64BitMaxMemorySizeInMB and VMPpc64BitMaxMemorySizeInMB to 1048576MB which prevents hot memory unplug from working.
