具体报错信息:

cloudstack org.libvirt.LibvirtException: internal error Attempt to migrate guest to the same host 00020003-0004-0005-0006-000700080009

解决方法:

#uuidgen                                   //获取一个uuid

#vi /etc/libvirt/libvirtd.conf           //编辑配置文件

host_uuid = ″00000000-0000-0000-0000-000000000000″ //将之前获取的uuid填在这里

#service libvirtd restart               //重启服务 应该就可以在线迁移了
