#3956 obsolete Vista x64 host, E_NOINTERFACE error (0x80004002) Atcom
Description

I installed Virtual Box 2.2.2 on Vista x64, with administrator privileges. After installation process, when i start the application the following error dialog appears: Failed to create the VirtualBox COM object. Callee RC: E_NOINTERFACE (0x80004002). I tried manually start VBoxSVC.exe, reregister it and reinstall the VirtualBox with disabled NOD32 4.0, but not solved the problem.

#3967 obsolete VBoxSVC.exe 100% CPU utilization with USB audio ndousis
Description

Hello,

In VirtualBox 2.1 and 2.2, VBoxSVC.exe uses 100% of 1 CPU core. I'm also using an external USB audio controller, which seems to be correlated with my problem. I read here (http://forums.virtualbox.org/viewtopic.php?p=23861) that 100% CPU utilization may result when another program using sound is running when a VM is started.

Configuration:

  • Intel Core 2 Duo
  • VirtualBox 2.2.2 r46594 win.amd64
  • host: Windows Vista 64-bit Home Premium SP1
  • guests:
    • 32-bit Windows XP Pro SP3
    • 32-bit Ubuntu 8.10
  • C-Media CM106 USB 3D audio controller (Toshiba Dynadock)

Matrix of scenarios that I've tested:

scenarioguest VMUSB audioVBoxSVC.exe
1on (WinXP or Ubuntu)on100% CPU
2on (WinXP or Ubuntu)offnormal
3offon or offnormal

A typical scenario is the following: USB audio is active; I start VirtualBox and power on my virtual machine (WinXP), and VBoxSVC.exe is running normally. As soon as I open the Zune player or go to Pandora.com, VBoxSVC.exe starts using a full CPU core, and will not stop, even after I exit my music player.

I'm using a Toshiba Dynadock docking adapter which has the USB audio chip. It seems that this VBoxSVC.exe issue disappears when my PC is not docked to the Dynadock.

#3975 obsolete WinXP guest display/keyboard extremely laggy on VB 2.2.2 Ubuntu host manankanchu
Description

After upgrading to VB 2.2.2. display and keyboard are extremely slow and laggy.

Typing at normal "2-finger" speed in and editors windows causesletters being omitted or mirrored. Cursors is always several letters back of typing.

Grabbing and then movin window around causes splitting of window into several pieces and then slowly reorganizing of window ... like in old times with graphic card too slow.

Fits to discussion on http://forums.virtualbox.org/viewtopic.php?f=2&t=16388

I'm using VB since a while and never had such problem on former 2.1.0
