as a workaround you can disable hot-plug memory in the db:
insert into vdc_options(option_name ,option_value,version) values('HotPlugMemorySupported','{"x86_64":"false","ppc64":"false"}','3.6');
if you do this, you need to remember to enable it back once this bug is solved

Description of problem: failed to start vm on top of rhevm 3.6.0.9 build, and host rhel 7.2 seems like Engine computes NUMA settings and VCPU settings separately, without cross-check the correctness
