I have/had the same problem. I run VirtualBox 3.0.12 r54655 on Ubuntu 9.10 and kernel 2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:53:52 UTC 2009 x86_64 GNU/Linux.

First I had problems with a CentOS 5.4 guest. The time was running at about half speed. The trick with the rt kernel solved this problem. With every new kernel I checked whether the problem has been solved and one or two weeks ago it finally was.

I never had problems with a Windows XP guest until today. I don't know whether it appeared with the last VirtualBox update or with the latest guest additions I installed today. The time was running sometimes too fast, sometimes too slow. After trying several things I seem to have solved the problem by disabling the VirtualBox Guest Addition Service.

Maybe you or anybody else with the same problem want to try this as a workaround for now and sync your time in another way.

Could you check if applying the change as posted in the ticket 5501 improves the behavior?

So, the solution to this is to install a kernel from the Lucid PPA - am I understanding that right? If so, what's the link for installing the Lucid PPA?

Same problem here. Solved today by decreasing the number of processors from 2 to 1.

VBox: 3.2.8
Host: Ubuntu 9.10 64 bit, AMD quad core, 8gb ram
Guest: Windows 7 64 bit: had 2 processors, decreased to 1 to solve the problem

I am afraid that you have not solved the problem. Reducing the CPU to a single processor always worked. The only way to fix it is to install the newer kernel from the PPA as described in the trac. I see that Ubuntu has also tried to fix the default 9.10 kernel but have not tried that fix. Launchpad does seem to have closed the tickets stating to upgrade to solve the issue.
