Sometimes I find nova-compute not update to db of controller. So I restart
nova-compute. But it stops in the stat:
"Connecting to libvirt: qemu:///system from (pid=22152) _get_connection
/data/nova/nova/virt/libvirt/connection.py:205".
Then I restart libvirt-bin service.
After that, the log show instances will be rebooted. How it happened?

This is debug show:
