OVM 3.3.4 to OLVM
获取OVS下vm主机信息
针对ORACLE VM Server下的testvm01进行迁移。
迁移过程需对testvm01关机操作
右键查看其VM Config File信息
记录以下信息
亦可通过查看vm.cfg获取相关信息
生成对应xml配置文件
将所有需迁移vm主机，生成对应xml配置文件
以下为xml文件需修改部分
以下为xml源文件
将文件复制到KVM主机
启动OVS服务器NFS服务
创建“Repository Export”
检查nfs服务状态
KVM服务器准备
安装所需组件
[root@ol7-kvm01 ~]# yum install oraclelinux-developer-release-el7 yum-utils -y
[root@ol7-kvm01 ~]# yum-config-manager --enable ol7_developer_kvm_utils
[root@ol7-kvm01 ~]# yum install qemu-block-curl拷贝OLVM证书到KVM服务器
[root@ol7-kvm01 ~]# scp 192.168.137.51:/etc/pki/ovirt-engine/ca.pem /root/ca.pem生成用于连接OLVM API的密码文件
[root@ol7-kvm01 ~]# echo "P@ss0lvm" >/tmp/ovirt-admin-passwordNFS挂载
KVM主机创建对应目录并挂载
[root@ol7-kvm01 ~]# mkdir -p /OVS/Repositories/0004fb0000030000681b0d6bd6435d1b
[root@ol7-kvm01 ~]# mount -t nfs 192.168.137.183:/OVS/Repositories/0004fb0000030000681b0d6bd6435d1b /OVS/Repositories/0004fb0000030000681b0d6bd6435d1b开始迁移

启动验证
打开“Compute”- “Virtual Machines”编辑迁移完成vm主机
核对修改vm主机名等信息
启动vm主机
打开Console查看启动过程
Console配置
Native Client
Windows主机需下载virt-viewer-x64进行安装方能连接到Console
https://virt-manager.org/download/sources/virt-viewer/virt-viewer-x64-11.0-1.0.msi
noVNC (Console Option)
下载CA证书，并安装到：受信任的根证书颁发机构
修改链接console的方式
OVM 3.4.x to OLVM （XML）
可根据 “6.1” 迁移方法手动修改xml文件进行迁移，以下将使用virsh生成所需对应xml文件
针对ORACLE VM Server下的ol7.1进行迁移。
启动xend服务
OVS服务器，修改配置文件开启http监听端口(8000)
# vi /etc/xen/xend-config.sxp ## Uncomment specified lines
(xend-http-server yes)
(xend-unix-path /var/lib/xend/xend-socket)
(xend-port 8000)重启“xend”及“libvirtd”服务
[root@ovms3 ~]# /etc/init.d/xend restart
[root@ovms3 ~]# /etc/init.d/libvirtd restartKVM主机连接测试（连接到OVS）
[root@ol7-kvm01 ~]# virsh -c xen+ssh://root@192.168.137.162 list --all
root@192.168.137.162's password:
Id Name State
--------------------------------------------------
0 Domain-0 running
6 0004fb0000060000c166a49d23eefc56 idle身份验证配置
获取KVM VDSM守护进程自身份验证到OVS服务器
# sudo -u vdsm ssh-keygen
# sudo -u vdsm ssh-copy-id root@<ovm-host>
# sudo -u vdsm ssh root@<ovm-host>Example：
启动OVS服务器NFS服务
创建“Repository Export”
检查nfs服务状态
KVM服务器准备
安装所需组件
[root@ol7-kvm01 ~]# yum install oraclelinux-developer-release-el7 yum-utils -y
[root@ol7-kvm01 ~]# yum-config-manager --enable ol7_developer_kvm_utils
[root@ol7-kvm01 ~]# yum install qemu-block-curl拷贝OLVM证书到KVM服务器

待迁移vm主机需为开机状态
确认主机信息
生成xml配置文件
# virsh -c xen+ssh://root@<ovm-host> dumpxml <vm-uuid> > <vm-name>.xmlExample：
关闭需迁移主机
迁移过程需对ol7.1关机操作
开始迁移

至此迁移完成
OVM 3.4.x to OLVM （Online）
以下将通过OLVM管理控制台连接OVM Xen进行迁移
针对ORACLE VM Server下的ol7.1进行迁移。
启动xend服务
OVS服务器，修改配置文件开启http监听端口(8000)
# vi /etc/xen/xend-config.sxp ## Uncomment specified lines
(xend-http-server yes)
(xend-unix-path /var/lib/xend/xend-socket)
(xend-port 8000)重启“xend”及“libvirtd”服务
[root@ovms3 ~]# /etc/init.d/xend restart
[root@ovms3 ~]# /etc/init.d/libvirtd restartKVM主机连接测试（连接到OVS）
[root@ol7-kvm01 ~]# virsh -c xen+ssh://root@192.168.137.162 list --all
root@192.168.137.162's password:

OLVM导入VM
打开“Compute” - “Virtual Machines”
Source选择“Xen”，输入OVS URL
将需迁移VM选中并提交到Import列表
OVM 3.4.6 to OLVM（未验证）
当前版本3.4.1验证测试失败，应是OVS版本问题，在OVS 3.4.6之后解决
OLVM服务器准备
安装必要组件
[root@ol7-olvm ~]# yum install python python-requests python-libs -y
[root@ol7-olvm ~]# yum install python-ovirt-engine-sdk4 -y创建目录并将证书拷贝到此目录
[root@ol7-olvm ~]# mkdir migrate_vm
[root@ol7-olvm ~]# cd migrate_vm/
[root@ol7-olvm ~]# cp /etc/pki/ovirt-engine/ca.pem .测试ssh连接到OVS和KVM主机
测试登录到ovmcli
上传migrate_vm.py
增加执行权限
[root@ol7-olvm ~]# chmod +x /root/migrate_vm/migrate_vm.py
执行迁移
验证测试失败
