ZStack Cloud supports USB passthrough, which enables you to pass through a USB device on a host directly to a VM instance. There are two passthrough modes:
Passthrough: Attach a USB device from a host to a VM instance located on the host. If you want to migrate the VM instance, detach the USB device first.
Forward: Attach a USB device from a host to a VM instance located in the same zone as the host. If you want to migrate the VM instance, you do not need to detach the USB device.
