Ticket #2510 (closed defect: fixed)
Snapshot fails if SATA port > 1
|Reported by:||erik||Owned by:|
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 . I believe these lines are causing the checks for isBusy() (/trunk/src/VBox/Main/HardDiskImpl.cpp) to fail.
