### User: How do you mount an ISO in virt-manager?[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=2 "Edit section: User: How do you mount an ISO in virt-manager?")

How do you mount an ISO in virt-manager?

### Assistant: In virt-manager, mounting an ISO is just attaching it as a virtual CD/DVD device.[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=3 "Edit section: Assistant: In virt-manager, mounting an ISO is just attaching it as a virtual CD/DVD device.")

In virt-manager, mounting an ISO is just attaching it as a virtual CD/DVD device. There are two common cases.

#### Attach an ISO to an existing VM[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=4 "Edit section: Attach an ISO to an existing VM")

1.   Shut down the VM (hot-plug sometimes works, but shutdown is the reliable path).
2.   Open virt-manager → select the VM.
3.   Click “Open” → “Show virtual hardware details” (lightbulb / ⓘ icon).
4.   Click “Add Hardware”.
5.   Choose “Storage”.
6.   Set: - Device type: CDROM device - Bus type: IDE or SATA (either is fine) - Storage: Select or create custom storage - Source path: browse to your .iso
7.   Click Finish.
8.   Start the VM.

The ISO will appear as a CD/DVD drive inside the guest.

#### Change / insert ISO while the VM is running[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=5 "Edit section: Change / insert ISO while the VM is running")

If the VM already has a CDROM device:

1.   Open the VM window.
2.   Click ⓘ Show virtual hardware details.
3.   Select the CDROM device in the left pane.
4.   Change Source path to the new ISO.
5.   Click Apply.

This works live for most guests.

#### Boot from the ISO (installer / rescue)[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=6 "Edit section: Boot from the ISO (installer / rescue)")

If you want the VM to boot from the ISO:

1.   With the VM powered off: - Open Boot Options.
2.   Enable “Enable boot menu” or move CDROM above Disk in boot order.
3.   Start the VM and choose the CD/DVD device.

#### Verify inside the guest[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=7 "Edit section: Verify inside the guest")

*   Linux: ```bash lsblk mount | grep sr``` Usually appears as /dev/sr0.
*   Windows: Shows up automatically as a DVD drive in Explorer.

#### CLI equivalent (useful for scripting)[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=8 "Edit section: CLI equivalent (useful for scripting)")

virsh attach-disk vm-name /path/to/file.iso sdb \
 --type cdrom --mode readonly

Detach:

virsh detach-disk vm-name sdb

##### Common pitfalls[edit](https://freemwiki.com/index.php?title=Openai/693dbcdd-dc90-8001-af6a-dd1cd177c9e7&action=edit&section=9 "Edit section: Common pitfalls")

*   ISO on a path libvirt can’t read (permissions / SELinux).
*   Using Disk instead of CDROM device.
*   Forgetting to adjust boot order for installers.

If you want, say what guest OS you’re using (Linux distro, Windows, installer vs data ISO) and whether this is a fresh install or an existing VM—I can be precise about bus type and boot settings.
