Johnson shows a great diagram that reviews all the various types of VM-to-VM communications that can exist in modern data centers: VM-to-VM (on the same host) via the software-based virtual switch (could be speeds of 30 to 40 Gbps in this use case). Intel VT-c actually provides a couple of different ways to work in virtualized environments.

Sure Virtualization Seems Neat In The Beginning, But…. To read the IT trade journals or speak with CIOs you’d think that we’ve all found the magic silver bullet that IT’s been looking for during the past few years: server virtualization. Virtualization has its own set of problems and we need to have a talk….

Insights into Data Center Infrastructure, Virtualization, and Cloud Computing. When a new server (physical or virtual) is created, much of this infrastructure also has to be provisioned to support it. That is, I/O is virtualized, networking is frequently converged (i.e. a Fabric), and network switches, load balancers, etc.
