#2510 closed defect (fixed)

Snapshot fails if SATA port > 1

Reported by: Erik Elmore Owned by:
Component: host support Version: VirtualBox 2.0.4
Keywords: Cc:
Guest type: other Host type: other


I have observed that it is impossible to take snapshots of a VirtualBox machine if it has any disk images attached to SATA ports 2 and higher. This condition results in an error message that the VDI file is is use by another task. I have reliably been able to reproduce this in a new VirtualBox VM by attaching any hard drives to any SATA port with the exception of 0 and 1 with Windows Vista Ultimate and Windows XP host operating systems and a variety of guest operating systems.

Although I have not set up a development environment for working on VirtualBox, I believe the problem can be traced to /trunk/src/VBox/Devices/PC/BIOS/rombios.c in the lines between 5392 and 5404 as it can be found in revision [13190]. I believe these lines are causing the checks for isBusy() (/trunk/src/VBox/Main/HardDiskImpl.cpp) to fail.
