  2. # This installs OpenvSwitch, KVM, Git(Hub) and an OpenFlow    #
  3. # Controller FloodLight (optional). It also downloads a 16Mb  #
  4. # linux-0.2.img.bz2 file that from http://wiki.qemu.org that  #
  5. # is great for testing networking since it is so lightweight  #
  6. # you can simulate lots of VMs running in nested a hypervisors#
  7. # on your laptop or older desktop rather than needing a server#
  8. # for learning or labbing. This is for *Ubuntu* only since it #
  9. # is using apt-get for pkg management.                        #
  10. # This is NOT for anything other than labbing and testing but #
  11. # the KVM and OpenvSwitch install would run production easily.#
  12. # Feel free to use this however you like. Python is a great   #
  13. # language for infrastrcuture applications. It has clean      #
  14. # abstraction leaving it easy to read but also has the power  #
  15. # of object oriented programming. This wil install a fully    #
  16. # working Software Defined Networking (SDN) and OpenFlow      #
  17. # lab in a few minutes. See the accompanying post             #
  18. # I recommend starting in a VM using VMware Fusion as the     #
  19. # first option only becuase it seems to deal with OVS better  #
  20. # than VirtualBox but both work. I would also recommend using #
  21. # snapshots heavily. Install your base Linux 12.04 build and  #
  22. # then take a snapshot in case you have problems with the     #
  23. # App you can rollback to the original snapshot and start over#
  24. # Comments at Twitters @networkstatic, Thanks-Brent Salisbury #
