I have been using a SBS 2008 server with 3 virtual server with VMware server 2.0 on of the VM server is running Peachtree premium accounting 2009. everthing has been going great but the last two weeks Peachtree server has been running super slow and the CPU is constantly ramping up to 100% then it comes down to 3 or 7 % and then ramps up again. just up and down without running anything .

VMWare, like most virtualization platforms, allows you to "oversubscribe" your CPUs. In other words. You can assign your limited CPU resources to dozens of VMs and the VMWare platform will attempt to allocate CPU power to all of them based on wait states, etc.

In such a scenario, the CPU usage in the guest OS lies because when it reports 100%, that isn't 100% of real CPU usage, that is 100% of the cpu it has been allocated by VMWare. VMWare detects that CPU usage is high, allocates more (if it can) so CPU usage in the VM drops, and when VMWare detects another VM needing CPU time, it reallocates, so you see "waves" of CPU usage.

VMWare provides its own performance tools to measure real CPU usage, but regardless, in this case the problem is clear. You are running more stuff than you have CPU power to drive so resources across the board are spread too thin causing performance issues. Time to shuffle some things around and (ideally) don't run SBS as a VM host.
