Description Ricardo Noriega 2016-05-04 11:12:11 UTC 
Description of problem:

'hw:cpu_thread_policy=prefer' allocates vCPUs in pairs of sibling threads properly. An odd number of vCPUs will allocate pairs and a single one. That single one should not be isolated. So 20 available threads, shall be able to allocate 4 VMs of 5 vCPUs. When booting up the third VM, it is giving an error.
