I wonder if someone might point me at something that illustrates the additional problems of securing something like VMWare? Assuming that all servers are maintained with firewalls, AV etc, that they are properly administered by a minimum number of staff and that that same minimum number have control over the virtual infrastructure itself then where is the additional risk? Is VMWare any better than Xenserver and/or Hyper-V in terms of security? Are these security problems easier in smaller deployments with a single team in control of everything?

I’d say VMware and Hyper-V are similar in that they allow you to virtualize servers with stability and consolidation in mind. Where they differ is management, features, and price.

When it comes to security, it all depends on how you implement the product. Enterprise class licenses for VMware are expensive, but they give you Cisco-built virtual switching which you can manage as if it was real equipment. Microsoft doesn’t have the versatility of the virtual switching, but their virtual network is just as secure if you set it up right.

Basically if you build the product using best practices, security will less of a concern.
