Ticket Resolution Summary Owner Reporter
#474 fixed Add a confirmation dialogue box for snapshot deletions jsambrook
Description

To avoid doing what I've just done I'd like to see an "Are you sure you want to delete <this> snapshot?" dialogue box at the appropriate points. Probably with a Preference setting to turn it off for those who'd not like it.

I just managed to delete a needed snapshot by fumbling the snapshot's context menu :(

#475 fixed 3D acceleration support for VBox guests Sander van Leeuwen
Description

This ticket is used to track development of 3d acceleration support.

I have committed my initial OpenGL guest support to the public SVN tree:

Current status:

  • communication framework between guest and host is present
  • simple OpenGL samples are functional; they display their rendered output in an external window on the host for testing purposes)
  • supported are only Windows guests combined with a Windows host
  • not all OpenGL commands are implemented; most simple ones are

Plans:

  • Linux host and guest OpenGL support
  • Add OpenGL extensions as reported by the host OS
  • Direct3D emulation using OpenGL

We are looking for external developers with an interest to help us out to complete this work.

Installation instructions:

To enable it you must add the following registry keys:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\OpenGLDrivers\VBoxOGL]
"Version"=dword:00000002
"DriverVersion"=dword:00000001
"Flags"=dword:00000001
"Dll"="VBoxOGL.dll" 

You need to build the latest additions from SVN as the OpenGL ICD mechanism needs a change in the display driver.

VBoxOGL.dll needs to be present in \Windows\System32.

TEMPORARY requirement: to enable OpenGL you must change src\VBox\Main\VMMDevInterface.cpp at line 606.

You can also directly link the OpenGL test cases with VBoxOGL.lib to test them directly.

  • replace $(PATH_SDK_W2K3DDKX86_LIB)/opengl32.lib with $(PATH_LIB)/VBoxOGL.lib in the makefile of the test cases
  • add VBOX_WITH_WGL_EXPORTS to VBoxOGL_DEFS in the VBoxOGL makefile

Enabling logging can be of invaluable help while debugging problems.

  • export the VBOX_LOG variable and set it to -all+shared_opengl+dev_vmm_backdoor
  • build the debug version of VBox

The full debug version of VBox adds quite a bit of overhead and might assert from time to time. For OpenGL debugging you only need to use the debug binaries of the hardware Devices (VBoxDD*.*). You can simply copy them into the directory with the full release version. (both must be at the same SVN level of course)
