• OpenStack.
  • Import the key pair "ISLv2-ISDA" in the web UI.  Needed when starting a new VM.
    Found that this was per user, not per project, so needed to import again.

• • Download and source "ISDA-openrc" in ~/.cshrc for OpenStack CLI programs such as "nova" to work. So one can use "nova list" to list the VMs.
  • Clone the "vm-elasticity" repo to get the code.
• SSH.
  
  • Run "ssh-keygen", to create an RSA key pair, put the pub key (content of "~/.ssh/id_rsa.pub") into ~/.ssh/authorized_key . Needed for elasticity code to ssh back into this machine without requiring password.
  • Copy "~/.ssh/config" to use the batch mode and enable fast connections.  Did not use ControlMaster.
• Elasticity.
  • Copy "bdmon.conf", change username / password to "browndog".
  • Install the "subprocess32" python module. Required by the elasticity code.
