This command is used to run a virtual machine using the QEMU emulator. Let's break it down:
-
qemu-system-i386
: This is the QEMU command to launch the virtual machine with the i386 (32-bit) architecture. QEMU is an open-source emulator that allows you to create and run virtual machines on various platforms. -
-hda ${image_name-img}
: This option specifies the hard drive image file for the virtual machine.${image_name-img}
is a placeholder for the actual image file name. It should be a disk image file containing the operating system and any files you want to use within the virtual machine. -
-cdrom ${os_image-iso}
: This option specifies the CD/DVD-ROM image that should be used as a virtual optical drive.${os_image-iso}
is a placeholder for the actual ISO file name. Typically, this ISO file contains an operating system installation image or an installation disc for software. -
-boot d
: This flag tells QEMU to boot the virtual machine from the CD/DVD-ROM (specified with-cdrom
) as the primary boot device. In this case, it will attempt to boot from the installation disc or ISO file.
By running this command, QEMU will start the virtual machine and try to install the operating system or software from the provided CD/DVD image file.
