local disk, and how to simulate it?This requires the creation of a local loopback device on the real hard disk, a part of the hard disk space, the creation of a local loopback device, while the device is in the form of a file and associated with the virtual disk of VMware Workstation. When a virtual machine stores data in a virtual disk, VMware Workstation is required to store its data in a local real file. Obviously, the disk performance of the virtual machine is not as good as the local real
