UNRAID下安装Virtual DSM

感谢chk-jxcn的分享！

一、安装镜像的准备

下载下来的镜像是原作者chk-jxcn(jxcn.org)从 DSM 中提取出的 VDSM 7.0 的安装镜像，未做任何修改。感谢chk-jxcn的无私分享！

该镜像比较大，两个都是20g，不太方便复制，所以自己提取安装镜像

在实体机或者虚拟机安装的DSM系统中，安装Virtual Machine Manager套件

在下载中心 - VirtualDSM | Synology 群晖科技 中，下载7.1.1-42962-up1映像到本地

打开VMM套件，点映像-DSM映像-新增-从计算机-选择下载好的VDSM映像，之后一直点下一步，最后显示状态良好就说明映像安装成功了

点虚拟机-新增-Synology Virtual DSM-下一步

名称、CPU、内存自定义

新建一个虚拟盘，容量填10GB，后面点下一步，等待虚拟机创建好

点击操作-导出-选择一个文件夹，导出模式默认是常规OVA，导出成功后，可以得到一个ova文件：

将该文件下载到本地计算机，使用解压软件解压，可得到vdsm-disk1.vmdk、vdsm-disk2.vmdk、vdsm-disk3.vmdk、vdsm-disk4.vmdk 4个Virtual Disk文件，将vdsm-disk1.vmdk、vdsm-disk2.vmdk 这2个文件上传到UNRAID目录中（自定义）

打开UNRAID终端，cd到存放vmdk的目录下，执行

qemu-img info vdsm-disk1.vmdk

得到如下输出，所以需将该文件转换为qcow2文件

image: vdsm-disk1.vmdk
file format: vmdk
virtual size: 10 GiB (10737418240 bytes)
disk size: 18.5 MiB
cluster_size: 65536
Format specific information:cid: 3271625478parent cid: 4294967295create type: streamOptimizedextents:[0]:compressed: truevirtual size: 10737418240filename: vdsm-disk1.vmdkcluster size: 65536format: 

输入如下命令，将vmdk文件转换成qcow2文件

qemu-img convert -c -O qcow2 vdsm-disk1.vmdk vdsm-disk1.qcow2

qemu-img convert -c -O qcow2 vdsm-disk2.vmdk vdsm-disk2.qcow2

二、创建用户数据盘

truncate -s 100G /opt/vdsm/user_data.img

三、导入xml

将vdsm_template.xml复制到该目录下，执行如下命令：

virsh define vdsm_template.xml

vdsm_template.xml内容如下：值得注意的是，引入vdsm-disk1.qcow2的时候，需要修改format=qcow2

<qemu:arg value='file=/mnt/user/domains/VDSM/vdsm-disk1.qcow2,if=none,id=drive-synoboot,format=qcow2,cache=none,aio=native,detect-zeroes=on'/>

四、启动虚拟机

virsh start VDSM
