Moving VirtualBox vhd to another location causes issue with uuid issues with the vhd

virtual machinevirtualbox

I have installed one virtual machine with a disk on my C: drive. It got annoyingly full and I had to move the vhd. To another location:

C:\..\VMs\vm1
F:\..\VMs\vm2

Then I regenerated the uuid for the HD like this (ran with admin privileges):

C:\..\VirtualBox> .\VBOXMANAGE.EXE internalcommands sethduuid "F:\..\.vmdk"
UUID changed to: 6d201451-721c-433b-98a3-6fef07e61feb

However when I try to attach the moved disk I get an error (below).

enter image description here

My VagrantBox.xml does not contain uuid's specified in the error. O have tried some variations with restart of the whole

Here it is:

The proper way to move a virtual drive is with the "Copy" feature of File > Virtual Media Manager (as described here: https://forums.virtualbox.org/viewtopic.php?f=3&t=14976 , thanks @Toris).

IF however you did the same mistake I did and used copy->paste of the disk and then fail to attach it use these steps:

  1. Go to VirtualBox management panel GUI;
  2. Press: File (top panel) -> Virtual Media Manager (VMM);
  3. Choose the hard disks that fail to attach properly and REMOVE them;
  4. Reattach them for each VM instance the normal way;

There were no UUID errors after I REMOVED the disk through (VMM) - in case you still get errors, please post here or in another question with the reference to this one, so we know this solution has been tried out.
