Bug 462302 – app-emulation/virtualbox-4.2.10: Can't access Win-Xp guest: Cannot attach medium '/usr/share/virtualbox/VBoxGuestAdditions.iso' medium is already associated with the current state of machine uuid

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Juergen Rose 2013-03-19 12:05:21 UTC]

I can't neither start nor modify the settings of my Win-XP guest from the gui.
I found several websites as

which stated, that the *.vbox file should be modified with an editor by removing the line with VboxGustAdditions.iso between the DVDImages tags. I did this with the file /home_leopard/rose/.VirtualBox/Machines/xpsp3leo/xpsp3leo.vbox, but it did not help, After restarting VM VirtualBox Manager I still have the same error:

Cannot attach medium '/usr/share/virtualbox/VBoxGuestAdditions.iso' {9a7a72fc-6c0a-49dc-a781-c2380205e466}: medium is already associated with the current state of machine uuid {1162bb0c-d72f-4450-90de-f5f506467c9f}!.

After removing also the 'AttachedDevice passthrough="false"' lines I could modify and start the virtual machine. I have seen this behaviour never before but at least on two systems in the last days.

This seems to be quite a confusing error.

I've tried to reproduce this on my two Windows XP VMs to no avail.

Do you have any idea how to reproduce it?
Did you try the suggestion from https://forums.virtualbox.org/viewtopic.php?f=6&t=46819 downgrading virtualbox to the last working version?

No response for over two years. Marking this bug as obsolete as the version is long gone from portage.
