我正在尝试在 VM Virtual Box 中运行 Op5 Monitor Virtual Appliance，但无法解决错误！我创建了一个虚拟机并尝试将“op5-Monitor-Virtual-Appliance-6.1.1-x86_64-disk1.vmdk”虚拟硬盘添加到新机器，但出现如下错误：
Failed to open the hard disk file D:\op5-Monitor-Virtual-Appliance-6.1.1-x86_64\op5-Monitor-Virtual-Appliance-6.1.1-x86_64-disk1.vmdk.
Could not get the storage format of the medium 'D:\op5-Monitor-Virtual-Appliance-6.1.1-x86_64\op5-Monitor-Virtual-Appliance-6.1.1-x86_64-disk1.vmdk' (VERR_NOT_SUPPORTED).
