Description
===========
I deployed ussuri env from ubuntu-cloud:ussuri.
Configure one compute node with xen and libvirt,
then nova-compute serivce can not be started.
Got error 'libvirt.libvirtError: this function is not supported by the connection driver: virNodeGetCPUMap'.

Steps to reproduce
==================
1. Install nova-compute
2. Configure nova.conf as below:
[libvirt]
virt_type = xen
3. Start nova-compute service

Expected result
===============
Nova-compute starts successfully

Actual result
=============
Got error
