VM inaccesible afetr crash

[Noel Burton-Krahn]

Host system running VirtualBox 4.0.4r70112 on Windows 7 64 bit

I created a snapshot of a running machine (Windows Server 2008, 64 bit), restored the snapshot, VirtualBox crashed with no error dialog. Now when I open Virtual box it says "The selected virtual machine is inaccessible". When I try to remove the old disk in Virtual Media Manager, I get this:

Result Code: VBOX_E_OBJECT_IN_USE (0x80BB000C) Component: Medium Interface: IMedium {9edda847-1279-4b0a-9af7-9d66251ccc18}

I also tried this on the command line:

"c:/Program Files/Oracle/VirtualBox/VBoxManage.exe" closemedium disk "./Server2008 Oracle ArcSDE.vdi" VBoxManage.exe: error: Cannot close medium 'c:\noel\.VirtualBox\HardDisks\Server2008 Oracle ArcSDE.vdi' because it has 1 child media VBoxManage.exe: error: Details: code VBOX_E_OBJECT_IN_USE (0x80bb000c), component Medium, interface IMedium, callee IUnknown Context: "Close()" at line 1182 of file VBoxManageDisk.cpp

How do I flip the "in-use" bit on a disk?

As a result of this bug your .xml / .vbox files are somehow corrupted. You have to repair them probably manually. That bug might have been fixed in the meantime, however, we still get reports that restore snapshot does not work reliable but this is reported elsewhere, for example in #8363.
