This can be done by setting the following:

Select Virtual Machines and Templates and click the Virtual Machines tab.

Right-click the virtual machine for which you are enabling the disk UUID attribute, and select Power > Power Off.
The virtual machine powers off.

Right-click the virtual machine, and click Edit Settings.

Click the Options tab, and select the General entry in the settings column.

Click Configuration Parameters. The Configuration Parameters window appears.

Click Add Row.

In the Name column, enter disk.EnableUUID.

In the Value column, enter TRUE.

Click OK and click Save.

Power on the virtual machine.

虚拟机磁盘类型是选择的scsi，但是在使用scsi_id -g -u -s /block/sda 确无法得到unid；
以上操作后就可以得到磁盘的unid
