　　管理端安装：http://www.ovirt.org/documentation/install-guide/chap-Installing_oVirt/
　　node安装 :http://www.ovirt.org/documentation/install-guide/chap-oVirt_Nodes/
　　管理端：
　　yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm
　　

　　node 节点iso:
　　

　　http://resources.ovirt.org/pub/ovirt-4.0/iso/ovirt-node-ng-installer/ovirt-node-ng-installer-ovirt-4.0-2016062412.iso
　　

　　rpm -ihv http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
　　

　　安装node 节点时，强烈建议自动分区
　　管理端yum仓库：

　　 NFS 修改
　　cat /etc/exports.d/ovirt-engine-iso-domain.exports
　　/var/lib/exports/iso*(rw)
　　systemctl restart nfs-server.service

[root@ovirt-engine yum.repos.d]# showmount -e 192.168.3.176

　　Export list for 192.168.3.176:
　　/var/lib/exports/iso *
　　检查一下 共享目录权限 的拥有人与拥有组是否有权限，并且是否都属于 vdsm kvm 这两个用户与组的
　　否则会挂载不上的

　　

　　之后打开主页
　　ovirt-engine.gewala.net （自己的主机名即可）自己设置的用户与密码：admin/admin
　　

　　node端：
　　我用自己的系统最小化安装，然后使用安装包做的node端
　　yum install vdsm vdsm-cli -y
　　如果启动失败vdsm服务，需要：
　　systemctl restart vdsmd  failed
　　vdsm-tool configure
　　systemctl stop sanlock
　　systemctl stop libvirtd
　　h端：主机名解析 /etc/hosts
　　启动相关服务有：
　　systemctl restart vdsmd
　　systemctl restart vdsm-network
　　systemctl restart vdsm-network-init.service
　　systemctl restart momd
　　systemctl restart momd-vdsm
　　安装node dashboard图形管理端：
　　yum install cockpit-ovirt-dashboard.noarch -y
　　如果要进Node 里面使用virsh 操作的话使用以下操作
　　useradd user
　　echo "password" | passwd --stdin user
　　 saslpasswd2 -a libvirt user
　　virsh 登录的时候输入user 用户名与密码即可
