Today I was reminded how easy it is to get fixed in your thinking.
The short lessons learned: if the Hostname fails (due to SSL) try the IP address.
Longer story:

ipxe.efi for aarch64
To make the AARCH64 ipxe process work using bifrost, I had to
git clone https://github.com/ipxe/ipxe.git cd ipxe/src/ make bin-arm64-efi/snponly.efi ARCH=arm64 sudo cp bin-arm64-efi/snponly.efi /var/lib/tftpboot/ipxe.efi |
This works for the Ampere reference implementation servers that use a Mellanox network interface card, which supports (only) snp.
How do you keep the Kolla Playing?

I need to modify how the ipxe container mounts directories. Why? AARCH64 iPXE stuff. Specifically, I need to get my own version of a file into the directory that a container mounts when it is running. How do I do that? I don’t know yet, so I am going to look.

For the past week I worked on getting a Ironic standalone to run on an Ampere AltraMax server in our lab. As I recently was able to get a baremetal node to boot, I wanted to record the steps I went through.

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.

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.
