From: Amador Pahim <apa...@redhat.com>
This issue was fixed in commit d81d857.
According to the RHBZ1431939, the issue is 'host nodes' returning '128'.
It should return empty value when using default policy or 0 when using
bind policy.
Test consists in inspect the result of the 'info memdev' QMP command
after hot-adding memory.
