CorrectISOを仮想CD/DVDドライブへ接続し、そのドライブから起動する

Correct. Attach the ISO to a virtual CD/DVD drive and boot from it.

Incorrect. Renaming the extension does not change how the hypervisor treats the image.

Use a disposable VM or test account when validating installation and SSH behavior.
Exact command output can vary slightly by distribution and OpenSSH version.

Foundation review

Attaching an image, selecting a boot device, and installing onto a virtual disk are separate operations.

After installation, detach the ISO or lower its boot priority so the guest does not re-enter the installer.
