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

[Jeffrey Williams]

Hi Guys,

Ok it is set, it does seem a little better, the clocks are still running 
ahead by an average of about 30-40 seconds, but they seem to have slowed 
down enough for ntpd to maintain the time by slewing, instead of 
stepping.  I did get a fresh batch of calcru errors from one of the 
servers right after reboot (possibly because I am setting 
kern.timecounter.hardware in sysctl.conf instead of loader.conf). I will 
let you know how it looks after it has run for an hour or two.

I tried TSC instead of i8254 on a third server, it was better than 
ACPI-safe, but much worse than i8254.

Thanks,
Jeff
