dhcplb virtual lab using vagrant and chef-solo

[pallotron]

One of the "problems" with the dhcplb project is that it's difficult to contribute it to it if you are not in that DC environment.

I have worked on setting up a virtual lab using VMs, it has been tested on my OSX laptop using vagrant and chef-solo cookbooks to set up the following:

• Ndhcpserver VMs: N VMs running ISC dhcpd (both v4 and v6) configured with a subnet in the private network space. You can start as many as you want by changing the variable on top of the Vagrantfile.
• dhcplb: a VM running the dhcplb itself, configured to foward traffic to the above;
• dhcprelay: a VM running ISC dhcrelay, it intercepts broadcast/multicast traffic from the client below and relays traffic to the above, it simulates a top of rack switch relay in the DC;
• dhcpclient: a VM you can use to run dhclient, or perfdhcp manually to test things. It's DISCOVER/SOLICIT messages will be picked up by the dhcprelay instance
