qemu: Boot from physical device (e.g. from USB to test bootable medium).

qemu-system-i386

$ qemu-system-i386 -hda /dev/${storage_device}

try on your machine

This command is used to start the QEMU (Quick EMUlator) system in i386 architecture, where the "-i386" flag specifies the machine type.

The "-hda" flag indicates that a disk image will be used as the virtual machine's primary hard disk. In this case, the specified disk image will be "/dev/${storage_device}", where "${storage_device}" represents the name of the storage device to be used.

Generally, in Linux systems, "/dev" is a directory that stores device files that represent various devices attached to the system. The storage device specified after "/dev/" should be an actual device, such as a physical hard drive or a disk image file.

Overall, this command starts the QEMU system using the i386 architecture and uses the specified storage device as the virtual machine's primary hard disk.
