#11317 obsolete Playing HD Video on Virtualbox Issue (3D & 2D) hkken
Description

I found that the Guest OS (Win XP) is very lag on playing HD Video. I have tested 3rd party Virtual Machine on the Same Host can be smoothly play that video.

Besides, I found there is a problem on enabling 2D Video Acceleration. The video will be broken when I enabled that feature.

Below is my Hardware of my laptop.

CPU: Intel Core I5 2467M /1.6 GHZ Chipset: HM65 RAM: DDR3 1333 8 GB RAM (2GB on the Guest OS) Display Card: Intel Graphics 3000 HDD: 500GB SATAII (5400RPM)

#11318 obsolete Kernel module vboxdrv : Inconsistent lock state mako
Description

Hi all,

the Linux kernel module vboxdrv of Virtualbox 4.2.6 (and also 4.2.4 and 4.2.2) uses an inconsistent lock state. According to the hint of Thomas Gleixner I enabled the kernel debugging feature "CONFIG_PROVE_LOCKING" in a vanilla kernel 3.2.34. (Please find my kernel config attached).

When loading vboxdrv.ko dmesg shows the following output:


vboxdrv: Found 4 processor cores. vboxdrv: fAsync=0 offMin=0x514 offMax=0x57f5

This behaviour leads likely to the freeze on a RT_PREEMPT system as described in ticket #11286. https://www.virtualbox.org/ticket/11286

#11319 obsolete Extension pack download is not secure eug
Description

The installer downloads the extension pack from http://dlc.sun.com.edgesuite.net/virtualbox/4.2.6. IMHO https should be used or there should be some kind of digital signature, even if it's just gpg.
