I have guest OSes (Win2K3 and Linux) running and these guest OSes have been experiencing a drift in their system clocks.<\/p>\n<p>The symptom is that:\u00a0\u00a0when the host and guest OSes\u00a0are booted and started, everything is running fine. After a few days or weeks, the clocks in the guest OSes\u00a0are drifting\u00a0 and becoming faster, so much faster that literally, every second in real life is about 3-4 seconds in the virtual machines!<\/p>\n<p>This causes a problem because one of my guest OSes is running an email server, and hence the timestamp on the emails were becoming skewed.<\/p>\n<p>Initially I thought the problem had to do with the dual core processing of AMD cpu and the outdated VM Server version, I have\u00a0made some tweaks and the clock skew improved\u00a0only but a little.<\/p>\n<p>Finally I think\u00a0I&#8217;ve found the answer &#8211; it is to do with the power saving feature (which changes the speed of\u00a0the processor)\u00a0on a motherboard.<\/p>\n<p><a href=\"http:\/\/kb.vmware.com\/selfservice\/microsites\/search.do?language=en_US&amp;cmd=displayKC&amp;externalId=1227\">http:\/\/kb.vmware.com\/selfservice\/microsites\/search.do?language=en_US&amp;cmd=displayKC&amp;externalId=1227<\/a><\/p>\n<p>Hope this will solve your problem as much as mine!<\/p>\n\n<!-- SEO Ultimate (http:\/\/www.seodesignsolutions.com\/wordpress-seo\/) - Code Inserter module -->\n<!-- SEO Ultimate after item content-->\r\n<!-- #SEO Ultimate after item content-->\n<!-- \/SEO Ultimate -->\n\n","protected":false},"excerpt":{"rendered":"<p>I have been scraching my head over a prolonged problem with VMWare&#8217;s free VMServer, where I have been using VMServer\u00a0(version 1.4).
