weather test successfully only on Compute Node

[liyang]

Recently I'm trying to integrate intel-nfv-ci-tests to our tempest, and I read some test code like this:
def get_host_numa_placement(instance, vcpus):

    out, _ = processutils.execute('ps -eo pid,cmd,args | awk \'/%s/ && '
                                  '!/grep/ {print $1}\'' %
                                  instance['id'], shell=True)
    if not out:
        return

    ...

    return placement

def _get_cpu_pinning(self, server):
    instance_name = server['OS-EXT-SRV-ATTR:instance_name']

    conn = libvirt.openReadOnly('qemu:///system')
    dom0 = conn.lookupByName(instance_name)
    root = ET.fromstring(dom0.XMLDesc()

    vcpupin_nodes = root.findall('./cputune/vcpupin')
    cpu_pinnings = {int(x.get('vcpu')): int(x.get('cpuset'))
                    for x in vcpupin_nodes if x is not None}

    return cpu_pinnings

It means that these tests can only run on the compute host node? Because it depend on the host machaine and hardware msupport. So if i want to test it successfully, out openstack platform must be all-in-one mode?
