Welcome back to the Virtual Monday Minute. Today's topic is Virtual Machine isolation--the ability of a host VMM to present each VM its own view of hardware resources, separate from any other VM. Whether you have 2 VMs or 20 on a single VMM layer, they know only the resources that they are presented, and they aren't aware that they are sharing the same physical hardware at the layer beneath the VMM. This is a very powerful feature of virtualization.
