Also, I know it's not answering the question you asked, but could you provide more detail on the failure you encountered with the Workstation Tech Preview? Now is the perfect time to report to us any issues you had, so that we have the opportunity to address them before the next release. If you haven't already done so, please start a thread in the VMware Workstation Technology Preview 2013 community so that we can investigate.
Thanks!
