Missing differencing image of snapshot

[rk2153]

Hi
I am running CentOS5.6
While the OS was running I took a snapshot and shutdown.
2 days later I tried to launch the VM and I got these errors

Failed to open virtual machine located in C:/Users/rkannan/CentOS5.9 64bit/CentOS5.5 64bit/CentOS5.5 64bit.vbox.

A differencing image of snapshot {86c9351f-b714-443f-9edc-5535134abb0c} could not be found. Could not find an open hard disk with UUID {9affb9d8-d3de-4f6b-9077-12a50209e1af}.

Result Code: E_FAIL (0x80004005)
Component: SnapshotMachine
Interface: IMachine {22781af3-1c96-4126-9edf-67a020e0e858}
Callee: IVirtualBox {3b2f08eb-b810-4715-bee0-bb06b9880ad2}

Thank you for your help.

Based on other conversations in this site on similar topics I am also uploading the vbox.xml

Did you "borrow" the VM from another user (lethakota)? If so, did you copy the entire VM directory? Is there a file named "9affb9d8-d3de-4f6b-9077-12a50209e1af.vdi" in your host?

Please post as a zipped attachment your "VBox.log".

Hi

Thank you very much for the response.

Yes, that is an VDI from a colleague. Given all the work, I decided to delete everything and re-install and back to running..

Do not wish to waste your time.

However, how can I learn more about this thile and the XML schema so I could make sense out of it.

You can read the manual about the location of VMs. The basic VDI, the logs and the snapshots are (after VBox 4.x) are all stored (typically) under the same folder, so you can copy the whole folder and move-it/use-it somewhere else. Now, in your situation it seems that you are referencing a CD outside of the default VM folder. It is an absolute path to which you do not have access. That's why it failed. If you want to edit the XML file manually, you're on your own, i.e. no support, no questions. Make a backup first.
