Description of problem:
Failed to run vm with numa pinning on host with one numa node under strict mode

Version-Release number of selected component (if applicable):
rhevm-3.6.1.3-0.1.el6.noarch

How reproducible:
Always

Steps to Reproduce:
1. Create vm(1024GB, 1 cpu) and pin it to host with one numa node
2. Create one numa node on vm and pin it to host numa node
3. Start vm

Actual results:
Vm failed to start
Error while executing action: 

test_numa:
Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:
The host cyan-vdsg.qa.lab.tlv.redhat.com did not satisfy internal filter Memory because cannot accommodate memory of VM's pinned virtual NUMA nodes within host's physical NUMA nodes..

Expected results:
vm succeed to run
