I was using a QEMU/KVM engine, but we are transitioning to the VMware engine now.
I found one mention (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cm d=displayKC&externalId=916) that the HOST OS's power management system may cause the VMware GUEST Clocks to vary. I'm going to try to disable the APM idling feature on the HOST and see if that helps. -Bruce -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stefan Bethke Sent: Wednesday, April 30, 2008 10:17 AM To: Wolfgang Hennerbichler Cc: [email protected] Subject: Re: [smokeping-users] Smokeping graphs from VMware slave is "choppy" Am 30.04.2008 um 16:06 schrieb Wolfgang Hennerbichler: > On Apr 30, 2008, at 16:01 , Chris Wilson wrote: >> Hi Bruce, >> >> On Wed, 30 Apr 2008, Bruce Mackey wrote: >> >>> I suspect there is some time synching issue involved, but when I >>> moved >>> my slave to a VMware image, I started getting choppy graphs. >> >> vmware time is all over the place.

I believe that VMware offers a stable time source, but I'm not sure which kernel, if any, can make use of it. If you wnat some form of virtualisation which does provide this kind of timing stability, I've used FreeBSD jails quite successfully. I also suspects that Solaris zones provide similar behaviour.
