I have a problem when using VBox 4.1.0 to clone a VM. I chose to clone the current state of one of my VM's and left the check box 'Reinitialize the MAC address of all network cards' clear.

I saw:

"Failed to clone the virtual machine <name>.
Cannot register the image ‘C:\Proqram FiIes\OracIe\VirtuaIBox\VBoxGuestAdditionsiso'
with UUID { <number> } because a CD/DVD image ‘C:\Proqram FiIes\OracIeVirtuaIBox/VBoxGuestAdditions.iso’
with UUID { <number> } already exists.

I then removed the guest additions ISO from the IDE Controller Storage Tree in Settings > Storage but I still got the same error.

I then tried to remove the guest additions ISO from Media Manager because it says that the iso is attached to snapshots 8 and 9 of my VM, but the 'Remove' button and menu options are disabled (greyed out).

perryg suggested:

Yes I have seen this very thing. You need to release the image from all of the snapshots as well. Usually this can be done in the media manager by selecting release for the guest additions . If however this does not work you need to start the snapshot and then use the device tab to remove it in each snapshot that still has it mounted. This has been reported before and AFAIK it was resolved, but now it appears that it has returned.

I have not succeeded in doing this yet.

So, in summary, the GUI clone tool does not work for my VM.

My .vbox file.

[David Aldrich]

As a workaround, mpack provided a manually corrected .vbox file (RSD_Centos5_5_x86_64_A (mpack).zip) that I can successfully clone (attached).

[David Aldrich]

Mannually corrected file (by mpack).

The error message you posted seems a little big strange formated. Can you confirm that in the first path the last slash (before VBoxGuestAdditions.iso) was "\" and on the second path "/"?

[David Aldrich]

Yes, strange but true. I will try to attach a screenshot of the actual message box to convince you ;-)

[David Aldrich]

Screenshot of error message.

[Christian Pötzsch]

Ok, this is the reason than. "\" is not the same as "/" on string comparison, but for paths it is ;). I have made a fix in SVN.

[David Aldrich]

Ok, thanks!

this is the actual error message virtualbox shows on windows while clonning:
​http://postimage.org/image/241yyncp0/
sure the guest additions has been installed.
without it there's no problem.
i'm stricken with the same problem.
i'm waiting it to be fixed in a short time or in the new release.

Can you confirm that this is finally fixed in VBox 4.1.2?

[David Aldrich]

Yes, it looks ok now with VBox 4.1.2. However, I can't be entirely sure that the bug is fixed because we had to hack the original .vdi file to workaround the problem. I cannot test with the original files.

Thanks for your help.

This issue has still not been resolved. I'm using v4.2.6.

Just received the following message after 1hr of cloning. Very Annoying!!! Is this going to remain a feature of Virtualbox, so that ones has to modify the .vbox file after waiting for hours for the error message? Or is it planned to be fixed at some point?

Please reopen if still relevant with a recent VirtualBox release.
