Hi all, I install devstack in ubuntu12.04 and upgrade libvirt 0.9.8 to 1.2.2. The libvirt version in my linux box is:
dujun@dujun-OptiPlex-3020:~/devstack$ virsh -v 1.2.2 And the error message in nova-cpu.log is such like that: 2014-12-03 11:00:13.007 ERROR nova.openstack.common.threadgroup [-] Connection to the hypervisor is broken on host: dujun-OptiPlex-3020 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup Traceback (most recent call last): 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/openstack/common/threadgroup.py", line 145, in wait 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup x.wait() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/openstack/common/threadgroup.py", line 47, in wait 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup return self.thread.wait() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/usr/local/lib/python2.7/dist-packages/eventlet/greenthread.py", line 173, in wait 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup return self._exit_event.wait() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/usr/local/lib/python2.7/dist-packages/eventlet/event.py", line 121, in wait 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup return hubs.get_hub().switch() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/usr/local/lib/python2.7/dist-packages/eventlet/hubs/hub.py", line 293, in switch 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup return self.greenlet.switch() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/usr/local/lib/python2.7/dist-packages/eventlet/greenthread.py", line 212, in main 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup result = function(*args, **kwargs) 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/openstack/common/service.py", line 492, in run_service 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup service.start() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/service.py", line 164, in start 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup self.manager.init_host() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/compute/manager.py", line 1124, in init_host 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup self.driver.init_host(host=self.host) 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/virt/libvirt/driver.py", line 507, in init_host 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup self._do_quality_warnings() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/virt/libvirt/driver.py", line 486, in _do_quality_warnings 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup caps = self._get_host_capabilities() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/virt/libvirt/driver.py", line 2991, in _get_host_capabilities 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup xmlstr = self._conn.getCapabilities() 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup File "/opt/stack/nova/nova/virt/libvirt/driver.py", line 543, in _get_connection 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup raise exception.HypervisorUnavailable(host=CONF.host) 2014-12-03 11:00:13.007 TRACE nova.openstack.common.threadgroup HypervisorUnavailable: Connection to the hypervisor is broken on host: dujun-OptiPlex-3020 I wonder why nova can't find the libvirt hypervisor since I have added compute_driver = libvirt.LibvirtDriver in /etc/nova/nova.conf. -- Regards, Frank
