Is it possible to mount and unmount CD-ROM in PVE 7 without requiring a restart/reset of the guest operating system?
 
So there are two different things that can be done:

  1. Unplug the whole CD/DVD-ROM device so that the VM does not even sees the device at all, that can only be done live (hot-unplugged) if the underlying device-bus supports it, i.e., it will work for SCSI but not for the default IDE.
  2. Eject the CD/DVD from the device, that is normally always support, independent of what device-bus is configured. Just select the CD/DVD-ROM device and click Edit (or double click it) and select "do not use any media" and confirm with "Ok", that should eject the ISO-image from the CD/DVD-ROM drive.1632374913075.png
 
Hello Thomas,

I am probably missing something. May I ask how do I achieve option #1. I do not see the option to add SCSI so I can mount an ISO image to it. Below are the only options that I see.

For option #2 that you described, wouldn't this require a bounce of the virtual machine for changes to take effect?

That option is a setting in the dialogue that will pop up when clicking on Add -> CD/DVD Drive:

What do you mean with bounce here? Normally editing the drive and selecting "Do not use any media" and confirming with "Ok" is all that's needed.
