oVirt支持虚拟机的HA配置, 当集群中有合适的机器可以接管failed的宿主机上的虚拟机时, 这些虚拟机会自动在同集群下的合适的主机上运行. 但是有几个前提条件 :

1. Power management must be configured for the hosts running the highly available virtual machines.
需要配置HA的虚拟机, 它的宿主机的电源管理必须配置.
2. The host running the highly available virtual machine must be part of a cluster which has other available hosts.
需要HA的虚拟机, 所在的cluster必须有其他主机可以运行这个虚拟机. 并且主机必须是运行状态.
3. The destination host must be running.
4. The source and destination host must have access to the data domain on which the virtual machine resides.
目标主机和当前运行虚拟机的主机, 必须同时可以访问数据域(如存放虚拟机的DISK IMG domain)
5. The source and destination host must have access to the same virtual networks and VLANs.
网络方面, 目标主机和当前的宿主机必须有同样的虚拟网络(网桥)和VLAN.
6. There must be enough CPUs on the destination host that are not in use to support the virtual machine's requirements.
资源方面, 目标主机必须有足够的CPU资源运行failover的虚拟机.
7. There must be enough RAM on the destination host that is not in use to support the virtual machine's requirements.

内存资源也是如此.
HA的切换时间可参考http://blog.163.com/digoal@126/blog/static/16387704020147119659409/进行配置.
配置比较简单 : 
首先查看集群中的主机, 切换只会发生在同一个集群的主机之间.
主机配置, 首先要配置管理卡, 包括用户角色, 开启LAN ipmi, 允许开关机等. (一般服务器都有WEB界面配置)
配置电源管理, 使用Test 测试电源管理是否正常.

还可以使用主机的电源管理, restart来看看是否可以重启服务器.

配置虚拟机, 打开虚拟机标签, 打开高级选项, 配置Host. 允许在集群中的任何主机运行.

同时迁移选项要允许手工和自动迁移.

配置HA, 勾选Highly Available.

测试虚拟机failover, 连接到当前运行虚拟机的主机, 把网卡停掉.
ifdown em1, 观察日志/var/log/ovirt-engine/engine.log, 看看会不会自动将虚拟机切换到另一台主机.
切换前应该会fence当前的宿主机. (通过配置的电源管理fence设备进行的)
运行3台虚拟机大概3分钟切换完. 这个应该是可以配置的, 当然也不能配置太短, 防止因抖动产生的切换.
有问题的话, 查看日志
