How do you mount an ISO in virt-manager?<br />
<br />
=== Assistant: In virt-manager, mounting an ISO is just attaching it as a virtual CD/DVD device. ===<br />
In virt-manager, mounting an ISO is just attaching it as a virtual CD/DVD device. There are two common cases.<br />
<br />
==== Attach an ISO to an existing VM ====<br />
# Shut down the VM (hot-plug sometimes works, but shutdown is the reliable path).<br />
# Open virt-manager → select the VM.<br />
# Click “Open” → “Show virtual hardware details” (lightbulb / ⓘ icon).<br />
# Click “Add Hardware”.<br />
# Choose “Storage”.<br />
# 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<br />
# Click Finish.<br />
# Start the VM.<br />
<br />
The ISO will appear as a CD/DVD drive inside the guest.<br />
<br />
==== Change / insert ISO while the VM is running ====<br />
<br />
If the VM already has a CDROM device:<br />
# Open the VM window.<br />
# Click ⓘ Show virtual hardware details.<br />
# Select the CDROM device in the left pane.<br />
# Change Source path to the new ISO.<br />
# Click Apply.<br />
<br />
This works live for most guests.<br />
<br />
==== Boot from the ISO (installer / rescue) ====<br />
<br />
If you want the VM to boot from the ISO:<br />
# With the VM powered off: - Open Boot Options.<br />
# Enable “Enable boot menu” or move CDROM above Disk in boot order.<br />
# Start the VM and choose the CD/DVD device.<br />
<br />
==== Verify inside the guest ====<br />
* Linux: ``<code>bash lsblk mount | grep sr </code>`` Usually appears as /dev/sr0.<br />
* Windows: Shows up automatically as a DVD drive in Explorer.<br />
<br />
==== CLI equivalent (useful for scripting) ====<br />
<br />
<syntaxhighlight lang="bash">virsh attach-disk vm-name /path/to/file.iso sdb \<br />
--type cdrom --mode readonly<br />
<br />
</syntaxhighlight><br />
<br />
Detach:<br />
<br />
<syntaxhighlight lang="bash">virsh detach-disk vm-name sdb<br />
<br />
</syntaxhighlight><br />
<br />
===== Common pitfalls =====<br />
* ISO on a path libvirt can’t read (permissions / SELinux).<br />
* Using Disk instead of CDROM device.<br />
* Forgetting to adjust boot order for installers.<br />
<br />
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.<br />
