When PXE Booting an AARCH64 server, the above message probably means that you are fetching an x86_64 image for iPXE, not ARM64. Here’s how I debugged it.

Enabling Fedora 35 Virtualization on an Ampere based machine
I have a fresh install of Fedora 35 on a lab machine. I want to run a virtual machine on it. I have ssh access to the root account and a public key copied over.

I’ve set up a second cluster, and the Ironic nodes are not PXE booting. Specifically, if I watch the nodes boot via an IPMI serial-on-lan console, I see that they send out a DHCP request and never get a response back.
This is a problem I am familiar with from my days at Penguin. Time to dig in and understand the networking setup on the controller to see why it is not getting the packet. Or, possibly, why it is getting it and the response is getting dropped.
I have another cluster that is working properly, and I am going to look at the setup there to try and contrast it with the broken set up, and figure out my problem.

Sometime your shell scripts get out of control. Sometimes you are proud of them. Sometimes….both.
I need to be able to re-add a bunch of nodes to an OpenStack cluster on a regular basis. Yes, I could do this with Ansible, but, well, Ansible is great for doing something via SSH, and this just needs to be done here and now. So shell is fine.
This started as a one liner, and got a bit bigger.

Ampere has two models of Servers out: Falcon and Mt. Jades. The Falcons are the older one, and make up many of our utility servers.
I recently had to get in to a serial console on the machine. The IPMI address hosts a web console. From that you can get a serial console on the server, but you need JNLP, which stands for Java Net Launch Protocol. It is implemented by IcedTea in OpenJDK: icedtea-web is the name of the RPM on Fedora 34.
What packages are Needed to build the Kernel
In my quest to automate the testing of the Linux Kernel, I need to automate the build of the Linux Kernel. To build the Kernel, you need the requisite packages. What are they? Let’s find out.

Here’s a one liner for showing the status of all your beaker jobs.
for JOB in $( bkr job-list -o $( bkr whoami | jq -r '.username' ) | jq -r ".[]" ) ; do bkr job-results $JOB | xpath -q -e "string(/job/recipeSet/recipe/@status)" ; done |
Remote build of the Linux Kernel via Ironic
Ampere Computing chips run the ARM64 instruction set. My laptop is a Dell running x86_64. In order to edit locally, but build remotely, I make use of servers in our datacenter. These are the steps I am taking.

Some custom jq for RegEx selection of OpenStack Ironic baremetal nodes. Our Server types show up in their names. I want to be able to build lists of only the Mt. Jade Servers, which have names that look like this:
jade09-r097
openstack baremetal node list --sort provision_state:asc -c UUID -c Name -f json | jq '.[] | select(.Name | test("jade."))' |
