How to Create an ISO Image for a Virtual Machine

There aren't too many options when it comes to creating an ISO from a virtual machine. If you're a Linux user, you can use commands like 'dd' and 'qemu-img' to convert VMDK to ISO. However, Windows users have to rely on third-party software for the job.

If your primary goal is to perform a virtual-to-physical (V2P) conversion, you have more options. You can choose to back up the entire system and restore it to physical hardware. In this article, we'll delve into both of these processes for converting a VM to an ISO and performing a V2P conversion.

What is an ISO image file? An ISO image file is a digital replica used to store the contents of an optical disc, commonly employed for backing up, distributing, or burning CDs, DVDs, or Blu-ray discs. The term "ISO" derives from the International Organization for Standardization, which established a standard format for representing the contents of an optical disc. An ISO image contains all the data present on a disc, including boot information, file systems, and folder structures. It is a single, readable file that can be mounted and accessed on a computer using specific software, without requiring the physical disc. Users can also burn ISO images onto blank discs to use them on devices without virtualization support. ISO images are widely utilized for software distribution, system installation media, games, and multimedia content.

An ISO image is a file containing an exact, byte-to-byte copy of a disk. It captures everything on the disk, including file system information, data, and bootable elements. Essentially, it's a complete snapshot of a virtual machine that can be stored and used for future backups, software distribution, or system recovery.

Create an ISO image using the QEMU-IMG command

Step 1: Install QEMU

QEMU is a generic and open source machine emulator and virtualizer. To install it on Ubuntu, use these commands:

This command is used to install the QEMU utilities on a Linux system based on Ubuntu or Debian. Run this command in your terminal to install the tools associated with QEMU, which will assist you with tasks related to QEMU virtualization.

For CentOS or Fedora, use:

Install qemu-img using the command sudo yum install qemu-img.

Step 2: Convert the VM disk to raw format

In this step, we will use qemu-img to convert the VM disk to raw format.

This command translates to: qemu-img convert -f vmdk -O raw source.vmdk target.raw In Chinese, this command reads: 使用qemu-img工具将VMDK格式的虚拟磁盘转换为RAW格式。源文件名为source.vmdk，目标文件名为target.raw。 This command is used to convert a virtual disk in VMDK format to RAW format using the `qemu-img` tool. "source.vmdk" refers to the source file name, and "target.raw" refers to the destination file name.

Please provide the English content you need translated, and I'll do my best to translate it into Chinese.

• `source.vmdk` is the path to the input file (your VMDK file).
• `target.raw` is the path to the output file (the raw disk image you're creating).

Step 3: Convert Raw to ISO

Now, we will use the `dd` command to convert the raw disk image into an ISO:

dd if=target.raw of=target.iso This command translates to: Copy the contents of the file target.raw to a new file named target.iso

Please provide the specific English content you would like translated, so I can assist you in translating it into Chinese.

• if stands for 'input file', which in our case is target.raw.
• of stands for 'output file', which in our case will be target.iso.

Note: You must run these commands with superuser privileges.
