I have a virtual machine with Windows XP with a clean installation. I set it as immutable to create a differential machine, so I create a new virtual machine, select the immutable hard disk and create a new snapshot in the new virtual machine folder.
However, when I try to start the virtual machine I get this error:
"failed to open a session for the virtual machine".

What is the problem? until now I can use differential virtual machines without problems. I have installed the last version or VirtualBox v4.3.4 and the problem persists.
If I set the hard driver as normal and I create a new virtual machine and select this hard drive I don't have any problem.
EDIT: I use the same virtual disk and do the same steps in another computer and it works fine. I think that the problem is the VirtualBox of my computer with the problem, but I try to uninstall the program and reinstall it and the problem persists, so I don't know how to solve the problem.
EDIT 2: if I set the virtual harddrive as multiattached instead of immutable, then it works fine. In my case is enough, but I know that it would be work as immutable because it was work until now and it works in another computer.
I try to create a new user in windows to try if the problem if with the configuration of my account, but the problem persists. So I think that some general configuration of VirtualBox has been corrupted and I am not be able to repair it.
I would like to know if there is any solution to use a immutable hard drive, because I would like to solve the problem with VirtualBox, although by the moment the multiattached hard disk is enough.
