Bug Description
version:master
problem:
NUMATopologyFilter fail when only one node has sibling while host has two node when cpu_thread_policy is require.
for example:
host has cpu info:
NUMA node0 CPU(s): 0-3,8-11
NUMA node1 CPU(s): 4-7,12-15
If vcpu_pin_set is 0-3,8-11, we can not boot instance with "hw:cpu_policy": "dedicated", "hw:cpu_
The log info:
host fails CPU policy requirements. Host does not have hyperthreading or hyperthreading is disabled, but 'require' threads policy was requested.
