FreeBSD 7, runaway clock as guest OS on Microsoft Virtual Server

Hi Folks,

I am trying to run FreeBSD 7 on Microsoft Virtual Server 2005 R2, 
Windows Server 2003, on a Dell 2950.

I am having a problem with the system clock running excessively fast, I 
initially tried installing 7.1 release but received a nearly continuous 
stream of the "calcru: runtime went backward errors", I tried rolling 
back to 7.0, and it improved somewhat, but I still received regular 
"calcru" errors, and it the system clock was running to fast for ntpd
to
keep up with it, I set sysctl kern.timecounter.hardware to i8254 (it 
tries to default to ACPI-safe), which helped more, ntpd is now able to 
keep pace with it, but only barely, and I haven't seen any
"calcru"
errors yet.

 From the boot time dmesg, on the CPU line, the frequency reported with 
in the parenthesizes varies on almost every reboot.

Are there any other adjustments I can make to get this under control?

Following are samples of sysctl values, dmesg, and a short log sample to 
show the time and time reset rates.

******** sysctl grep clockrate:

kern.clockrate: { hz = 1000, tick = 1000, profhz = 1024, stathz = 128 }

Have you tried reducing the value of kern.hz (kern.hz="100" in
/boot/loader.conf)? That fixes some clock-related problems on VMWare
Server.

Add the following to your /boot/loader.conf file:

kern.hz="100"

I always use this setting with FreeBSD under VMware, and it solves all
these timing problems for me.  (But YMMV.)

However, I am not sure what is at fault here, VMware or FreeBSD...  I'd
guess the latter, since neither Linux nor Windows guest OSes seem to
have any such timing problems.

I use VMware, not VirtualServer, but you might want to set kern.hz in
your loader.conf to something less than 1000. I use the following:

kern.hz="100"

That, combined with vmware-tools' option to sync the VM clock to the
host works very well for me.
