#500 fixed Ubuntu timing (unresponsiveness) problems on Turion64 X2 Edulix
Description

The machine feels really slow and unresponsive and it seems related to timing problems with my CPU, which is an AMD Turion64 X2. I'm using Ubuntu 7.04 as the host and Windows XP SP2 as the guest SO.

This is what I get:

00:00:00.000 TM: u64DeltaPrev=-13260680356091 u64PrevNanoTS=0x003d3786df9b5251 u64NanoTS=0x003d2b776176f156 u64Delta=0x3d0900
00:00:00.000 TM: u64DeltaPrev=-13260692348318 u64PrevNanoTS=0x003d3786e0524ef4 u64NanoTS=0x003d2b776176f156 u64Delta=0x3d0900
00:00:00.000 TM: u64DeltaPrev=-13260700346642 u64PrevNanoTS=0x003d3786e0cc5a68 u64NanoTS=0x003d2b776176f156 u64Delta=0x3d0900
00:00:00.000 TM: u64DeltaPrev=-13260712349782 u64PrevNanoTS=0x003d3786e18381ac u64NanoTS=0x003d2b776176f156 u64Delta=0x3d0900

Lots (megabytes) of lines of this kind appear in /home/edulix/.VirtualBox/Machines//TecnovaLogs/ files. I have already 4 log files (the maximun stored) and one of them is of more than 20 megabytes.

Note that this doesn't happen always that I boot the guest, but when it starts then there's no way back. And the problem very frequently.

#10983 fixed EFI Video modes not work after reset VM -> fixed in SVN Edward
Description

I set "VBoxInternal2/EfiGopMode" to 4.

  1. Boot VM, it is 1440*900.
  2. Reset VM, it becomes 640*480.
  3. Power off and boot again, it goes back to 1440*900.
#11636 fixed No Audio on OS X guest on OS X host Edward
Description

The guest OS X detected Intel HD Audio, and the AppleHDA driver worked.

However, no audio input & output devices were found on guest OS X.

On the host OS X side, the VBox.log shows that:

00:00:02.915671 Audio: Trying driver 'coreaudio'.
00:00:02.941214 CoreAudio: Using input device: Built-in Microphone (UID: AppleHDAEngineInput:1B,0,1,0:1)
00:00:02.953257 HDAcodec: can't open in fmt(freq: 44100)
00:00:02.954443 CoreAudio: Using output device: Built-in Output (UID: AppleHDAEngineOutput:1B,0,1,1:0)
00:00:02.956674 HDAcodec: can't open out fmt(freq: 44100)

It seems to be a problem in VirtualBox on the host side.
