[Kimchi-devel] [PATCH 0/5] [Memory HotPlug] Implements backend of memory device hotplug

[Crístian Deives]

This patchset breaks some tests when running "make check" on Fedora 21.

Also, why do we need to create the subresource "memdevices"? Why can't 
we hotplug memory by setting a new value to the VM 'memory', as in:

PUT /vms/myvm {'memory': 1000}
