vmdk stops working when upgrading 5.1.30 -> 5.2.12 (Error ID: DrvVD_DISKFULL)

[Mikael Djurfeldt]

When upgrading to version 5.2 (all versions up to and including 5.2.12, my virtual disk has stopped working. The machine is paused at startup and yields the error message below (Error ID: DrvVD_DISKFULL). If I resume the machine, it seems to run sluggishly and never boots.

I attach a log from an attempt to start using version 5.2.4 and my vmdk file (which uses the raw disk). Note that this file has worked perfectly for many versions of VirtualBox up until and including 5.1.30.

Also, if I downgrade to 5.1.30 again, my virtual machine with its ram disk works again.

If I go into settings in VirtualBox manager and look at "Storage", it says:

Virtual Size: 476.94 GB Actual Size: 1.86 TB

which I find strange...

Here's the error message I get when trying to start the machine using 5.2 versions:

An error has occurred during virtual machine execution! The error details are shown below. You may try to correct the error and resume the virtual machine execution.

Host system reported disk full. VM execution is suspended. You can resume after freeing some space.

Error ID: DrvVD_DISKFULL Severity: Non-Fatal Error

The problem remains in 5.2.18.

This is definitely a duplicate of #17431. If everybody was opening a ticket for every new VirtualBox version, the ticket database is going to fill pretty soon! :D
