About Adam Young

Once upon a time I was an Army Officer, but that was long ago. Now I work as a Software Engineer. I climb rocks, play saxophone, and spend way too much time in front of a computer.

Launching a VM From the virt-install command line interface

I do this infrequently enough that I want to record a reminder how I do it:

sudo cp ~/Downloads/rhel-server-7.6-x86_64-kvm.qcow2 /var/lib/libvirt/images/tower.qcow2
sudo virt-install --vcpus=2  --name tower  --ram 4096  --import  --disk /var/lib/libvirt/images/tower.qcow2

Manually Adding SSH Keys to a Cloud Image

Not all of my virtual machines run on OpenStack; I have to run a fair number of virtual machines on my personal workstation via libvirt. However, I like using the cloud versions of RHEL, as they most closely match what I do run in OpenStack. The disconnect is that the Cloud images are designed to accept cloud-init, which pulls the ssh public keys from a metadata web server. Without that, there are no public keys added to the cloud-user account, and the VM is unaccessable. Here is how I add the ssh keys manually.

Creating a Self Trust In Keystone

Lets say you are an administrator of an OpenStack cloud. This means you are pretty much all powerful in the deployment. Now, you need to perform some operation, but you don’t want to give it full admin privileges? Why? well, do you work as root on your Linux box? I hope note. Here’s how to set up a self trust for a reduced set of roles on your token.

Imagining Go With Alternate Boards

The Game of Go is still pretty much the ultimate strategy game.  No other game distills strategy to its essence, in such simplicity, and thus lets the complexity emerge. 

The board is simplicity itself: a 19 X 19 Grid:

Standard Go board

One aspect of Go is that you start from the corners, build a semi-secure formation, and then grow out from there.

For example, here is a recent game of mine in the early stages:

Both my opponent and I have staked out positions in the corners.

What if the board was a little different?

Converting a RHEL Workstation to a Server

My laptop is my Demo machine.  I need to be able to run the Red Hat cloud Suite of software on it.  I want to install this software the same way a customer would.  However, much of this software is server side software, and my machine was registered as a workstation. This means the Red Hat Content network won’t show me the server yum repositories.  Here is how I converted my machine to be a server.
