(In reply to commit-hook from comment #28)

This patch broke VirtualBox for me (12.2amd/64, with VDI files accessed via
NFSv4).
Starting any machine, I get:
VDI: error reading pre-header in '....vdi' (VERR_DEV_IO_ERROR).
VD: error VERR_VD_VDI_INVALID_HEADER opening image file '....vdi'
(VERR_VD_VDI_INVALID_HEADER).
Failed to open image '....vdi' in read-write mode (VERR_VD_VDI_INVALID_HEADER).
AHCI: Failed to attach drive to Port0 (VERR_VD_VDI_INVALID_HEADER).


Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed} 



I can confirm reverting this brings VBox in a working state again.
