Timer problems

Reported by: r.pietsch@… Owned by:
Priority: major Component: other
Version: VirtualBox 3.2.6 Keywords:
Cc: Guest type: Windows
Host type: Linux

Description

There is a serious timer problem at least in the combination Host: Ubuntu 10.04 64Bit, Kernel 2.6.32-23-server CPU: AMD Phenom(tm) II X4 965 Processor Memory: 8GB

Guest1: "Tomcat" Ubuntu 10.04 32Bit, Kernel 2.6.32-22-generic Guest2: "Convert" Windows XP SP3 32Bit.

Both guests show a seriously slow timer. It looks like 1 second in the guests is about 3 "Real" seconds. It look like this problem is independent from the guest-os but depends on the number of guests that are active.

There is deffinitely a dependence to the number of active guests.

If there is only 1 guest active the time is Ok.

If there are more than 1 guest active the error occure. This is independent of the actual load. even if all guests are idle and the host shows a total load of less than 5% this timer difference happens. There is no difference if the host uses "nohz" or "highres" to on or off. It also does not depend if the guest-additions are installed or not.

One more info:

On an other machine

System=Ubuntu 9.10 x86_64 CPU=AMD Athlon(tm) II X4 630 Processor Kernel=2.6.31-20-server, VirtualBox=3.1.6r59338

everything works fine.

System=Ubuntu 10.04 x86_64 CPU=AMD Phenom(tm) II X4 965 Processor Kernel=2.6.32-23-server VirtualBox=3.2.6r63112

The error occurs.
