在qemu.conf配置文件中修改了user 和group后导致上面的报错，一开始写xml报错，还真以为是权限的问题，都改为root，重启了nova_libvirt容器问题依旧。厥后又将user和group改回到nova
  1. stdio_handler = "file"
  2. user = "nova"
  3. group = "nova"

经过pdb调试代码，发现跟踪到了libvirt驱动去创建xml的 报错
代码位置：/var/lib/kolla/venv/lib/python2.7/site-packages/nova/virt/libvirt/drivert.py
  1.     def _create_domain(self, xml=None, domain=None,
  2.                        power_on=True, pause=False, post_xml_callback=None):
  3.         """Create a domain.
  5.         Either domain or xml must be passed in. If both are passed, then
  6.         the domain definition is overwritten from the xml.
  8.         :returns guest.Guest: Guest just created
  9.         """
  10.         if xml:
  11.             guest = libvirt_guest.Guest.create(xml, self._host)
  12.             if post_xml_callback is not None:
  13.                 post_xml_callback()
  14.         else:
  15.             guest = libvirt_guest.Guest(domain)
  17.         if power_on or pause:
  18.             guest.launch(pause=pause)
  20.         if not utils.is_neutron():
  21.             guest.enable_hairpin()
  23.         return guest
复制代码
终极在guest.launch的时候报Libvirt Error
办理：
在qemu.conf配置文件中添加namespaces = []后，重启libvirt服务正常工作。
  1. stdio_handler = "file"
  2. namespaces = []
  3. user = "nova"
  4. group = "nova"
