  1. Have you tried helping yourself by searching for "VERR_PDM_MEDIA_LOCKED"? Rhetorical question...
  2. One of your VMs (or a snapshot of your VMs) has the VirtualBox Guest Additions (GAs) CD still mounted. Open the Virtual Media Manager and go to the Optical Disks and see which VM has the GAs CD mounted. Unmount it from that VM. And do not use saved states, shutdown the VM completely.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
