创建nova实例 nova-compute报错：libvirtError: internal error: process exited while connecting to monitor

在vmware嵌套的虚拟化环境中，摆设多节点，对接多套后端ceph存储的时候，发现创建nova实例总是error：

• 根据卷类型和镜像创建卷
  

1. cinder create --image-id 2bc3e25e-d6fc-4b61-96c9-d24075ec05fd --name test-bus-22 --volume-type ceph-bus 10

复制代码

• 启动一个nova实例
  

1. nova boot --flavor 1C1G --boot-volume 4602fd51-ceba-4e11-9bf7-07ab59fbc4cb  --availability-zone business --nic net-id=ef6e073d-be57-48d0-8a6d-c0aeb566f3c3 --nic net-id=56f13591-b4ba-4cd8-8ec6-1cebad6438dc bus-test122

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"
