Virtual machine inaccessible

[blixt]

Hello. After I closed and reopened VirtualBox, one of the VMs was suddenly inaccessible. The error description is the following:

Code: Select all

Hard disk 'C:\Documents and Settings\a403761\.VirtualBox\VDI\Windows XP.vdi' with UUID {2a321369-7c91-4890-8afd-997fe972e5e0} is already attached to a machine with UUID {05a60796-91c9-46e0-84c9-8adc02c91fef} (see 'C:\Documents and Settings\a403761\.VirtualBox\Machines\Windows XP\Windows XP.xml').

Result Code: E_FAIL (0x80004005)
Component: Machine
Interface: IMachine {31f7169f-14da-4c55-8cb6-a3665186e35e}

Now the funny thing is that I looked in the XML file, and the VM I get the error in is the one with the UUID {05a60796-91c9-46e0-84c9-8adc02c91fef}. So basically I'm getting an error that the hard disk image for the VM is already attached to the VM so it can't be attached to the VM. Catch-22 anyone?

Is there any solution to this?

Host OS: Windows XP
Guest OS: Windows XP
VirtualBox version: 1.5.6


Update
One thing I noticed when comparing the Windows XP.xml file and an XML file for another VM is that for the XP VM, the UUID of the <HardDiskAttachment> tag in the <Hardware> section of the <Machine> is the same as the UUID of the <HardDiskAttachment> tag in the <Hardware> section of the first <Snapshot>. In the other VM XML file, the UUIDs differed. Could this be the cause of the error?

I've had this trouble before too, it can be resolved without loosing everything. Just re-build the machine and when it's time to give ti a hard drive file, give it the existing one. You may have to go to the virtual drive manager and de-list it from the other machine that you'll wipe out. Keep in mind, though, that this does not save your snapshots, just the current disk.
