2.编辑libvirt/connection.py
/usr/lib/python2.7/dist-packages/nova/virt/libvirt/connection.py

reboot happens, as the guest OS cannot ignore this action.

"""
- virt_dom = self._conn.lookupByName(instance['name'])
+ # NOTE: In case of no domain up
+ try:
+ virt_dom = self._conn.lookupByName(instance['name'])
+ except Exception, e:
+ virt_dom = None

if not xml:
- xml = virt_dom.XMLDesc(0)
+ if virt_dom:
+ xml = virt_dom.XMLDesc(0)
+ else:

self.plug_vifs(instance, network_info)
self.firewall_driver.setup_basic_filtering(instance, network_info)
self.firewall_driver.prepare_instance_filter(instance, network_info)

复制代码

3.最后请切换到/path/to/instances/
cd instance-000000XXX
virsh define libvirt.xml

4.reboot instance
