Failed to open virtual machine...

[velo2k77]

The server running virtualbox locked up and I had to power cycle it. The virtual machine was running and had a snapshot. Now when I try to run the virtual machine I get the following error:

Failed to open virtual machine located in /Users/bcox/VirtualBox VMs/CentosMin_Web/CentosMin_Web.vbox.
A differencing image of snapshot {94e77d8d-0673-4f2b-9156-9f4300a66d0b} could not be found. Could not find an open hard disk with UUID {e6a6e6e8-de01-4cc0-bd36-0b50e5dace93}.

Any ideas on what I can do?

You might get it back by looking in the guests folder for a file *.vbox-prev where * is the name of the guest.
Backup this file and rename it to *.vbox after removing/renaming the original *.vbox

Thanks for your response. I tried your suggestion but didn't have any luck. I ended up using clonevdi to consolidate the snapshot and created a new VM to use the cloned vdi and voila:

I lost the ability to resort back to the old vm state but I'll take this over losing the whole VM any day.
