#5911 obsolete Mini toolbar (when Fullscreen) does not always dropdown/popup when un-pinned Mark Cranness
Description

When in Fullscreen mode a mini toolbar is/can be displayed. If you mouse over it, it is supposed to popup/dropdown.

Only mouse-over over the Machine or Devices menu (on the mini-toolbar) cause the toolbar to popup/dropdown. Mouse-over over the pin or VM name (snaphot) or Fullscreen icon or close icon DO NOT cause the toolbar to popup/dropdown, but should do so.

#6865 worksforme part of VM BIOS is overwritten during boot Mark Cranness
Description

VirtualBox contains a 0x10000 (65536) byte BIOS used as the VM boots. At some point after VM boot, part of the BIOS (bytes F000:0F00 thru 0FFF) are overwritten and corrupted.

That range corresponds to part of function keyboard_init(), which apparently is not yet corrupted during POST, but at some later point is overwritten, and for the default BIOS this overwrite (apparently) causes no problems.

But if a user uses a custom BIOS file, this overwrite may cause problems.

#7280 obsolete Take a snapshot and attached disks are detached Mark Cranness
Description

In some circumstances (VMs with shared attachments), taking a snapshot causes attached drives to be un-attached / removed.

Repro:

  • Two new machines (A, B) with no attachments, 5 virtual disks: A1, A3, B1, B3, SHARED.
  • Attach to A the following disks (in this order): A1, shared, A3 and add a CD/DVD controller and drive and a floppy controller and drive.
  • Attach to B the following disks, B1, shared, B3 and add a CD/DVD controller and drive and floppy controller and drive.
  • Take a snapshot on A. Not that now only A1 is attached, and the other disks AND the CD/DVD drive and floppy drive have been removed.
  • Attempt to-reattach A3 to VM A. Note that A3 is shown with the blue star icon, indicating that a differencing disk is attached somewhere (so VB thinks).
  • Virtual Media Manager > Observe that A3 does NOT have a differencing disk.
  • Restore Snapshot on A and Delete Snapshot on A
  • (STRANGE!) Repeat add drives to A and snapshot and this time the snapshot does not remove the attachments!
  • Delete Snapshot, and observe: "Failed to delete the Snapshot 1 of the virtual machine A. Medium 'C:\...Shared.VDI' is locked for writing by another task."
  • Close VirtualBox, wait for VBoxSVC.exe to stop, Delete snapshot 1 works. Re-add snapshot, followed by Delete snapshot gives error above again.
