Cannot attach medium VBoxGuestAdditions.iso

[koops]

Hi there,

This is my 'inaccessible' virtual machine. I was trying to uninstall an old vbox guest additions so I had multiple guest additions mounted when my host system crashed.

I believe I have the same issue as Mary Ann in the thread: "[Solved] Cannot attach medium ... medium is already associated with the current state of machine" (I can't add the link as this is my first post)

It seems like @mpack did some magic on the virtual machine and repaired it. How may I fix this?

I've also attached my virtual machine if anyone would like to have a look.

It doth appear that you have almost the same issue in your Lubuntu guest that the linked poster had. You have two CD drives in your guest, and both have the same Guest Additions ISO inserted:

<DVDImages>
  <Image uuid="{4470bc09-1149-42c7-a122-65823e7f72f2}" location="C:/Program Files/Oracle/VirtualBox/VBoxGuestAdditions.iso"/>
</DVDImages>
..........
<StorageController name="IDE" type="PIIX4" PortCount="2" useHostIOCache="true" Bootable="true">
  <AttachedDevice passthrough="false" type="DVD" hotpluggable="false" port="1" device="0">
    <Image uuid="{4470bc09-1149-42c7-a122-65823e7f72f2}"/>
  </AttachedDevice>
  <AttachedDevice passthrough="false" type="DVD" hotpluggable="false" port="0" device="0">
    <Image uuid="{4470bc09-1149-42c7-a122-65823e7f72f2}"/>
  </AttachedDevice>
</StorageController>

Based on Mpack's solution in the linked thread, to remove the ISO's from the CD drives, Here's what the same sections would look like:

<DVDImages/>
........
<StorageController name="IDE" type="PIIX4" PortCount="2" useHostIOCache="true" Bootable="true">
  <AttachedDevice passthrough="false" type="DVD" hotpluggable="false" port="1" device="0" />
  <AttachedDevice passthrough="false" type="DVD" hotpluggable="false" port="0" device="0" />
</StorageController>

These edits are in this Lubuntu.vbox file. Turn off all things related to Virtualbox, maybe reboot your host so there's nothing running related to Virtualbox. Then make a backup copy of the Lubuntu.vbox file you have now, then copy this edited file into the guest folder over the top of the original.

Actually, you don't even need two DVD drives, just one.

<StorageController name="IDE" type="PIIX4" PortCount="1" useHostIOCache="true" Bootable="true">
  <AttachedDevice passthrough="false" type="DVD" hotpluggable="false" port="0" device="0" />
</StorageController>

Thanks so much @socrates. Unfortunately when I load the edited vbox file it gives an error: extra content at the end of the document (line 93)

However when I check line 93 it refers to the </VirtualBox> tag so I'm unsure hwo to resolve it. Any suggestions?

Thanks so much @mpack, what did you do to fix it?

[mpack]

I didn't. I started from scratch from your first post of it. Easier than trying to count brackets in an XML.
