Deploying the DevStack Host VM

You can set up DevStack directly on physical hardware, but I would highly recommend that you use a desktop virtualization tool such as VMware Workstation or Fusion. You probably already have it installed in your system. We are going to set up a new VM for our DevStack and set up specific networking for that VM to assure that everything works as desired.

I suggest you to download the Ubuntu 14.04 desktop 64-bit installer ISO for your host VM. At the time of this writing, the current master repo for DevStack works well with this version of Ubuntu. Plus, it is painless to install in the latest version of VMware's desktop hypervisors, using the "Easy Install" feature, which answers nearly all of the deployment questions automatically.

Because we are in fact going to install all of our OpenStack environment into this host VM, you will want to set the configuration a little larger than you might be used to for normal desktop OS VMs. I would recommend that you give the VM at least 6 GB of memory. With only 4 GB, you will experience a small amount of memory swapping just to stand up the OpenStack environment. It will work, but if you have a system that has the RAM, go ahead and set the VM to 6 GB of memory or more. Since my workstation has 32 GB of RAM, I am using 8 GB for my VM. Next, you will want to give the VM at least 2 CPUs. This is the bare minimum. Since I have a system that can handle it, I am setting my VMs CPU count to 4. Be sure to enable the Virtualization options on the CPUs in Virtual Machine Settings, as shown in the following image. Next, you should allow the VM to have some disk breathing room by setting a large hard disk size. I went with a 180 GB drive.
