#4062 closed defect (fixed)

host OS cpu always is above 50%

Reported by: yup Owned by:
Component: other Version: VirtualBox 2.2.2

Guest type: Windows Host type: Linux


I have linux debian squeeze as host os cpu: amd64 dc mem: 4gb

virtualbox-2.2.2-46594_Debian_lenny from (not virtualbox-ose)

(same problem was with virtualbox-ose from debian repo)

I have installed windows 2003 server as guest os ( ram 512mb, video 8mb, acpi on, vt on, 1 network interface). Is works fine.

host's (linux) cpu load is near 2-3% while guest os idle. If I start few programs ( openoffice, drweb, winrar, etc ...) cpu load of host (linux) jums to ~100% and when programs started it returns to 2-3%

cpu load of guest (windows) also falls to 0-1%

there is a program named QIP - alternative icq client (

when I run this (installed) program on guest OS (windows) I get above 50% of cpu load on my host OS (linux) and 0-1% on guest OS (windows), the same thing if I run some more programs (openoffice etc.) but when I close qip, load gets to normal (2-3%) on host OS

maybe this is qip specific but why guest OS does not show great cpu load or maybe this is virtualbox hardware specific

when I start other guest box (winxp) both guests do not get more than 5% of cpu on host OS (linux) when i close that second guest (winxp) cpu load return to above 50% on host OS

same thing happens when qip runs on winxp

Try again with a newer version of VirtualBox and include the VBox.log of such a session should the problem persist.
