问题：快照永远处于“创建”状态。

影响：因此无法获取快照，因此无法启动/停止CloudStack UI中的实例

请参阅以下代理日志中的跟踪，该日志是在我单击Cloudstack UI中的快照按钮时编写的：

2014-02-25 17:27:09,129 WARN [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-4:null) Unsupported command
为了再次重新启动实例，我手动删除了mysql数据库中与此卡住的快照对应的vm_snapshots表中的行

请向我建议修复方案，并对此问题进行适当解释

提前谢谢

问候,，
Rohit

这方面有什么更新吗？
