Virtualbox Guest Service uses 100% CPU

Reported by: guest Owned by:
Component: guest additions Version: VirtualBox 4.2.6
Keywords: 100% cpu guest service Cc:
Guest type: Windows Host type: Windows


The Virtualbox Guest Service uses 100% CPU in 64-bit Windows 8 guests.
Stopping the Virtualbox Guest Service fixes the problem until the guest reboots.

Virtualbox version 4.2.6
Guest: Windows 8 (64-bit)
Host: Windows 7 (64-bit)

Unable to reproduce. No CPU load afer upgrade/install additions on newly created Windows 8 guest. Can you provide more information about guest memory size, 3d enabled/disabled etc?

Also occurs with Windows 7 64 bit guest and Ubuntu 12.04 host before the guest additions were updated.

I had the same problem.
Version: VirtualBox 4.3.6 r91406
Host: Ubuntu 12.04 - 64 bit
Guest: Windows 8 - 32 bit

RAM: 1024 MB
Chipset: PIIX3
"Enable I/O APIC" enabled
1 CPU with PAE/NX enabled
VT-x and nested paging enabled
Video Memory: 32 MB
Monitor number: 1
No extended video features (2D / 3D acceleration)
Audio enabled with driver ALSA and controller Intel HD Audio
Network: NAT mode with Intel PRO/1000 MT Desktop

I use many other VMs with Windows XP and Windows 7, but I had this problem only with Windows 8 machine.

Now I have uninstalled and reinstalled Guest Additions, and the problem seems solved (no more VirtualBox Guest Service using a lot of CPU).
