在一个集群中有两个主机kvm-A和kvm-B,现在我想实现如下目标：如果主机kvm-A异常断电了，那么运行在kvm-A的虚拟机（如VM-1）能够自动运行到kvm-B上
目前我只知道，要选择启用“提供高可用性”性能，但是即使选择了高可用性之后，当我将主机kvm-A断电时，等一段时间从Cloudstack上面看，原来在kvm-A上面的虚拟机VM-1确实显示所属的主机改成了kvm-B，但是一直starting，不能成功启动（部分日志见下）。我的主存储用的是CLVM的卷组VG，通过kvm-A和kvm-B连接到iscsi存储，不知道这种存储有关系没有。Cloudstack版本4.0.2.
下面是部分日志：[root@management-secondary ~]# tailf
