Preparing boot media for virtual machines

Before creating a virtual machine, you need to prepare a source with a guest operating system, to boot the VM from it. You can use the following media:

  • An ISO image is a typical OS distribution that needs to be installed on disk. You can upload an ISO image to the compute cluster.
  • A template is a ready boot volume in the QCOW2 (rarely RAW or IMG) format with an installed operating system and applications. Many OS vendors offer templates of their operating systems under the name “cloud images”. You can upload a cloud image from the OS official repository or prepare your own template in the compute cluster.
  • A boot volume with an installed operating system and applications. You can prepare a boot volume in the compute cluster.
