VM won't start: medium is already in use by this snapshot

[uruguayiandude]

Hello guys,

I restarted my mac, and much to my surprise the linux VM became inaccessible and the following error appeared:

Code: Select all

Cannot attach medium '/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso' {6fc4e532-cc81-4e7f-9780-0d78f25abdff} from snapshot 'f4a28b32-ffe5-48a9-b665-f7e650bc9f43': medium is already in use by this snapshot!.

Result Code: VBOX_E_OBJECT_IN_USE (0x80BB000C)
Component: MediumWrap
Interface: IMedium {4afe423b-43e0-e9d0-82e8-ceb307940dda}

I spent a lot of hours configuring that VM, so any help that can prevent me from doing that again, and to actually getting that VM up and running again would be super appreciated.

Thanks in advance.

Delete any snapshots, leaving your VM at the "Current State".
In the VM Settings remove the VBoxGuestAdditions.iso.

Moving to "OSX Hosts" from "OSX Guests".

Thanks for the quick reply.

However, I can't access the snapshot GUI. How can I delete those? Sorry for my ignorance, but I'm new to Mac.

Thanks in advance.

Why's that? If you've got a snapshot, then you've used this before...

If you hover over a VM, you'll see the tools option (). Click on that, select "Snapshots". Start deleting the previous/oldest snapshots until you're left with the "Current State".

I just tried, and the snapshots option is greyed out, can't delete any of those (or access it for that matter) from the Virtual Box tool itself.

I would like to see the "recipe" of the VM, the ".vbox" file:

1. Right-click on the VM in the VirtualBox Manager. Select "Show in Finder".
2. ZIP the selected ".vbox" file and attach it to your response.
