Open Stack

The libvirt driver logs a warning if:
    hostarch not in (arch.I686, arch.X86_64))
The warning when I start the libvirt driver on system z (arch.S390X) 
will be:
    "The libvirt driver is not tested on kvm/s390x by the OpenStack 
    project and thus its quality can not be ensured. For more 
    information, see: 
    https://wiki.openstack.org/wiki/HypervisorSupportMatrix"

I'm not quite sure if I understand that correctly. Should this be a
hint that "arch.I686, arch.X86_64" is the assumed "default"?
Or am I supposed to add the architecture "S390X" to this method because
this platform is listed in the hypervisor support matrix? 
I want to avoid that customers will get a bad feeling because of the 
warning after starting the nova libvirt driver on a system z platform.

Note: We are still working on the CI for nova
