P2V Best Practices

Posted on 2010-01-06

Hello Experts,
I recently converted an XP desktop machine to an EXSI quad core xeon server using VMware convertor 4.01 and the desktop VM is now running slowly and freezes at times. I will re-try the conversion. Could folks give me their recommended method for P2V conversions. Should one run sysprep first on the physical desktop machine? Would it be better to use say...Acronis with universal restore to backup the machine and then restore it to the VM? What is the cleanest way to make the conversion that will give me the best performance. I really appreciate your time!

    Accepted Solution

    Uninstall or disable any physical hardware related services prior doing P2V, if the VM is good, you then shutdown the physical machine
    You normally use sysprep/newsid if you want to clone or deploy to many VMs(Windows based), for this you dont have to P2V, just create a fresh new VM and install fresh new guest OS, if you dont have vCenter you basically cant clone or create template but it os still possible to clone VMs by copying the vmdk

    The Converter guide doesn't give much as far as what should/shouldn't be stopped on the source OS, except File Sharing (, pg 38-39). Sysprep shouldn't have to be used since you're doing a P2V - the VM will be the same "PC" as the physical (you'll need to power down the physical once the conversion is complete/successful). Using the Converter Standalone tool is as clean as any other product, but if you want clean, you would need to just build up a new VM. My recommendation for that is to build up different OS-based templates (WinXP, W2K3, W2K8) and use them to deploy new VMs.

    Hope that helps.
