好像是Libvirt的一个bug

谢谢，我到 google 后也得到了这个答案，是否有其他解决方法？
我基于 centos6.3 做的 openstack，控制节点上的计算节点可以正常 Suspend Instance，但单独的计算节点就不行，同样的版本啊，郁闷！

你的计算节点，是否安装nova api？

谢谢陈老师的回答，^_^
我的计算节点安装的是:  nova-2012.1.1.tar.gz 这个包，安装步骤与控制节点一样，nova api 有单独的安装包吗？
实例都能正常通过 horizon 的 dashboard 来分配到计算节点，实例运行一切正常，只是做不了 Suspend Instance，Snapshot 等操作。

SELECT * FROM instance_faults
可以看到错误信息。

贴出libvirt  版本及 libvirt.log

谢谢，版本及日志如下：
libvirt-0.9.10-21.el6.x86_64

centos 6.3 自带libvirt不存在此bug

问google妥妥的！
