Question : Best way to manage development virtual machines

Was looking for a best practice when it comes to managing and deploying virtual machines used by developers.  These vm's will be run on each developers local machine through Virtual PC 2007.  Does anyone have a good method of doing this?

Was thinking of just making a standard catalog, with 8 or 9 virtual machines containing different software.  Should I set them up as I need them, then just turn them off and store the vhd's on a network share?  Or do I need to do some type of "generalizing" them vm's (uninstalling drivers, using sysprep, ect)?

Thanks!

Answer : Best way to manage development virtual machines

if you want to deploy the VMs on different computers talking to each other, you need to sysprep the VMs otherwise you will get problems.
Making a catalog is quite a good idea.
Don't you have the possibility to leverage Hyper-V with self-service portal to deploy VM on demand ?
Another good solution for this is to leverage a VDI solution
