  • 1.  Host CPU reports usage at 100%, guest only reporting usage of ~5%

    Posted Jan 28, 2010 03:42 PM

    Hi,

    I recently P2V'ed a widnows server 2003 machine, the new VM reports under the performance tab that the CPU is running at 100%, if I look in the guest it is only using ~5%, the original server had 4 CPU's which I have reduced to 1 vCPU.

    The 100% usage is throwing an error message and I'd like to work out why there is such a large discrepancy between the two.

    Thanks

    Steve

    By host CPU reports, I mean that vCentre is reporitng 100% usage of the CPU.

    I don't know if this would necessarily be the cause of the problem, but did you change the HAL from multiprocessor to uniprocessor?

    make sure that all non-essential software is uninstalled from add/remove programs. problems happen when the VM has software installed that's still looking for the physical hardware. even after that, you may never find the problem cause and the final resolution is to do a clean build of windows and move the app(s) over to it.
