虚拟机注册到Virtualbox失败，从stackoverflow上看到的solution
I'm running v6. Starting this morning, I can't import some VMs, and some of my existing VMs are showing up as inaccessible and have the following error showing in the UI.
The same error too when i took the vm to another PC and try to open it with virtual box (v 5.0.10):
Cannot register the DVD image 'D:\iso\CentOS-7-x86_64-DVD-2003.iso' {fb46588b-6527-4887-aab9-090cebbc67ea} because a CD/DVD image 'D:\iso\CentOS-7-x86_64-DVD-2003.iso' with UUID {b75f650f-cc2b-4217-b9a6-cc1f0f205f97} already exists.
I solved it by open the file win 7 64.vbox
with text editor and remove the tag:
<DVDImages> <Image uuid="{fd686a98-c1a6-42d9-82aa-67728b524d53}" location="C:/Program Files/Oracle/VirtualBox/VBoxGuestAdditions.iso"/></DVDImages>
Know that by removing the tag it will be added as empty tag. and reopent the vm of virtual box again. and it worked
Open the .VBOX file in any text editor of your choice.find the following lines:
[...]<DVDImages> <Image uuid="{b058bc48-c451-4cff-9db0-d01c70e99c28}"location="/usr/share/virtualbox/VBoxGuestAdditions.iso"/>[...]
Delete all entries between and section. After deleting the contents, your .VBOX file will look like below.
<DVDImages></DVDImages>
Save and close the file.
That’s it. Now, you can load the virtual machine without any issues.
