Unable to start VMs after restore

Post by veg »

Hi all :-)

I have do perform a Rollback (using Rollback RX) yesterday night. The VMs are located in F: drive which is not affected by Rollback.
I have opened the VirtualBox, clicked machine > add and then I have tried to select one of the VMs (IE11 - Win7.vbox)
I get the following error message:
Failed to open virtual machine located in F:/Virtual Machine/IE11 - Win7/IE11 - Win7.vbox

A differencing image of snapshot {41941d27-917f-4882-a368-049cae701f3d} could not be found. Could not find an open hard disk with UUID {bde68043-8ff1-492b-a27d-b1134367a3a2}.

Result Code: E_FAIL (0x80004005)
Component: SnapshotMachine
Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}
Callee: IVirtualBox {d0a0163f-e254-4e5b-a1f2-011cf991c38d}
Can someone please help me out? thanks!

You mean that you don't take a backup of the VMs with Rollback, right?

Why did you try to "Add" a VM? Wasn't that VM already present/registered with VirtualBox?

Yes. Rollback RX is configured to take snapshots of C drive only. I had to restore to the beginning of September, while the VirtualBox was empty.

The VMs were created 1-2 days ago in F:\ drive so the rollback does not change any data in that drive.

Another issue:
I tried to add Cyberops Workstation VM which I was using... another error pops up
Could not find an open hard disk with UUID {387bb7c5-bc41-4713-bf8d-043b45da4e98}.

Result Code: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)

That won't change the situation...

I need to see the following as a first step:
  1. The file "C:\Users\<you>\.VirtualBox\VirtualBox.xml". Note the period in the ".VirtualBox".
  2. The output of the following command when run from the Command Prompt:
    • dir /s "F:/Virtual Machine/"

Of course, it will... it worked.
Before doing that, I managed to fix the cyber ops VM using this guide http://blog.htxiong.com/2013/06/resolve ... -open.html
Then I wanted to apply the same method on the Win7 VMs but those had snapshots... so I tried to create a new UUID for the hard disk and for each snapshot. I have updated it but it didn't work. So I have deployed 2 new VMs.

I have no clue what you're describing here, only that you linked to a 6-year old blog post...

The solution of this 6-year old solved the issue with the Cyberops VM.

As for the Win7 VMs - I have created a new UUID for the virtual hard disk and for each snapshot and then I edited the file, but it didn't work.
Here is an example:
cd "C:\Program Files\Oracle\VirtualBox\"
VBoxManage.exe internalcommands sethduuid "D:\NewVM\myDisk1.vdi" >>> you will get a new UUID for the vdi file (hard disk / snapshot)
