#12594 obsolete Guru Meditation: Invalid Jump Instruction wjk
Description

I am trying to boot a custom kernel (based on the one used in OS X Server) in VirtualBox. It keeps giving me a Guru Meditation (log attached) at a location I have resolved to the following instruction:

ljmpl $0x08,$64f

($64f is a reference to the next line of assembler, which reads 64:.)

I believe that the jump instruction is either invalid, or it causes a bug in VirtualBox to manifest. Does anyone have an idea which is which?

(Minor bug because while this is very important to me, it is important to pretty much no one else. I would still appreciate an answer, though. I’m sorry if this isn’t an appropriate bug, but I know of nowhere else to ask it.)

#4126 obsolete New version update mangled network connection settings in WinXP (host) Wayne
Description

I have WinXP host, and openSUSE 11.1 guest installation. I upgraded from VirtualBox 2.1.4 to VirtualBox 2.2.2. The installation disabled the wireless network connection for WinXP and created a new one. The new one had all of the wrong settings, and resulted in my not having any wireless connection at all. Fortunately, I am knowledgeable enough to know what to check and what to change in order to re-enable my wireless connectivity. Unfortunately, others may not. This is certainly a bug.

I don't know if there are any files to attach to this bug report. Please, let me know if you require one and where I can find it.

Thank you.

#8858 obsolete Ubuntu 11.04 guest fullscreen graphics are broken with 3D enabled Jacob Buys
Description
  • Software:
    • VirtualBox 4.0.6, Windows 7 (64bit) host,
    • Ubuntu 11.04 Desktop (32bit GA) guest with 4.0.6 additions installed with DKMS.
  • Hardware:
    • Lenovo T510 laptop,
    • Intel GMA HD graphics,
    • Latest BIOS and graphics drivers.

My goal is to get Unity working, which requires 3D support.

3D acceleration works fine in windowed mode, even when maximized. Hovewer, when I then attempt to go to fullscreen mode, the guest display no longer redraws or responds properly: it looks like it's not drawing any 3D effects, and only redraws the screen when they have ended. If I leave fullscreen mode, everything works properly again.

Sometimes, entering, leaving and entering fullscreen mode in quick succession solves the redrawing problem, but keeps the resolution the same as it was in windowed mode.

Booting the VM into fullscreen mode has the same problem.

The problem does not occur when 3D acceleration is disabled (but then obviously compiz/unity does not work).

This problem is present in all 4.0.x versions of VirtualBox (I have not tested older versions than 4.0.0).
