nova重置虚拟机状态

遇到一个报错虚拟机的状态一直是错误或者创建中，硬重启都解决不了。

[root@node-1 ~]# nova reboot --hard 011dc8e8-969c-4e32-aaf0-173d645078b7

Cannot 'reboot' instance 5300e364-a2de-4d51-a847-e21fa0d3492d while it is in task_state rebuilding (HTTP 409) (Request-ID: req-067291db-149d-4e7e-a7e3-d9fdc057eb67)
ERROR (CommandError): Unable to reboot the specified server(s).
[root@node-1 ~]#

这时候只有通过 nova reset-state 先恢复状态了，该指令会把 instance 的 Task State 恢复为 None，然后就正常了。

[root@node-1 ~]# nova --help|grep reset
    reset-network               Reset network of a server.
    reset-state                 Reset the state of a server.

状态已经修复，可以 stop && start 了

[root@node-1 ~]# nova reset-state 5300e364-a2de-4d51-a847-e21fa0d3492d
