Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have two virtual machines on different servers and I want to measure lan speed between these two VMS. I want to use iperf. The problem is that my VMs are host only and their ip address is only valid in their host. Not only for iperf, I want to know in general how can I communicate with VMs from another VM?
For e.g my first VM has ip x on server a and my second VM has ip y on server b. When I try to ping VM2 inside VM1, it assumes that it should look for y on server a. How can I say this VM is on another server b?
you can't say "it's on a different server", you need to deal with these things generically with proper networking. Either you'd route it between the hosts, from one internal subnet to another (note that the two vm networks would need to be different), or my preferred option would be to use bridged networking to make the VM's reside on the same network as the two hosts, meaning all machines can communicate with all others.
Thanks for reply, I did not get what you means, could you please explain? I want to know how can I provide a route between to host?
