The JEOS approach does not work well with Windows. Specifically patch management / gold image management with desktop vms where there is a high density of vms with the same base image (say Win7). It is more economical and easier to "discard" the unpatched / previous image than to maintain patches on each desktop vm. The bonus is that the vm maintains its identity (mac / ip) which seems critical for some desktop apps.
