Running many virtual machines on a single host

I have a need to run a relatively large number of virtual machines on a relatively small number of physical hosts. Each virtual machine isn't doing to much - each only needs to run essentially one basic network service - think SMTP or the like. Furthermore, the load on each is going to be extremely light. Unfortunately, the numbers are...

registers vs stacks

What exactly are the advantages and disadvantages to using a register-based virtual machine versus using a stack-based virtual machine? To me, it would seem as though a register based machine would be more straight-forward to program and more efficient. So why is it that the JVM, the CLR, and the Python VM are all stack-based? ...

Pros and Cons of Developing on a VM on a PC

I recently build myself a semi beef up PC (Q9450, 8GB DDR2 1066, 1TB HDD, Dual 8600GT, Vista Ultimate and Dual 22' Monitors) and I'm evaluating whether i should develop on a VPC/VMWare session on top of Vista or not? One benefit i can see is that i can run the same VM on my Vista laptop so my development environment is the same on any o...

Reasons to Use a VM For Development

Background: I work at a start-up company, where one team uses Virtual Machines to connect to a remote server to do their development, and another team (the team I'm on) uses local IIS/SQL Server 2005/Visual Studio installations to conduct work.
