Description
Change ISO media for a running guest.
Setup
Functioning virt host and VM. All VM OS welcome.
How to test
Add an empty CDROM device
If the guest does not have a CDROM device attached to it, add one:
- Open virt-manager. Start with a shutoff VM.
- Details->Add Hardware->Storage
- Select 'Select managed or existing storage' but leave the text field blank. This creates a CDROM device with no media attached.
- Select Device type: IDE CDROM
- Select Finish
Change media in virt-manager
- Start the VM. Log in to the desktop environment.
- In virt-manager, select the CDROM device in the Details window.
- Click 'Connect'. Specify ISO media of your choice. Click 'OK'.
- Verify that the media is accessible in the guest.
- In virt-manager, click 'Disconnect'.
- Verify the media is no longer present in the guest.
Change media with virsh
- With the guest still running as above, stay connected to the guest with virt-manager
- In a terminal, insert media to the cdrom:
sudo virsh change-media test-day-vm hda /path/to/my.iso - Verify the media is usable in the guest
- Eject the media:
sudo virsh change-media test-day-vm hda --eject - Verify the media is no longer present in the guest.
Expected Results
No obvious errors occur.
