[Kimchi-devel] [PATCH 0/4 v4] [Memory HotPlug] Implements backend of memory device hotplug

[Rodrigo Trujillo]

v4:
- Fix issues with tests
- Add new memory hotplug test


v3:
* Implemented sugestions from Aline's review:
   - removed memory devices API;
   - Improved vm update function to check if vm is running and 
     update memory accordingly;
   - moved xml function to xmlutils;
   - removed libvirt checking from attachDeviceFlags test function
   - moved maxMemory to osinfo.py
* Fixed some issues with CPU update


V2
- Fix erros in tests and add a test to slots number
- Fix other minor issues with Libvirt < 1.2.14


V1
This patchset implements the backend part of memory hotplug functionality,
including:
- new feature test to check if libvirt supports memory devices
- changes the way that memory is assigned or updated in the guest xml:
	* memory is now set in a basic NUMA node
- includes maxMemory element in the XML:
	* which is equal the total memory of the host
	* sets memory device slots. The total number of slots are equal the
          maxMemory minus the memory assigned (1 slot == 1 GB )
- creates a new VM device, the memory device:
	* by default, a memory device will have 1GB
	* user can add the memory device with machine running or offline
- memory devices are selected according to its position in the xml (the slot)
  0, 1, 2, etc
