In the previous part of the guide we have completed our basic system intallation, and we are now ready to move into actually configuring Xen. After rebooting we can verify that our bridge is correctly configured and that we are actually in Xen with Dom0 using only 512 megs and 1 CPU. andromeda root@andromeda:~# brctl show bridge name bridge id STP enabled interfaces virbr1 8000.00163ed10be7 yes virbr1-dummy xenbr0 8000.

Although Kubernetes supports the excellent minikube for development purposes, it is nice to be able to have an actual “real” Kubernetes cluster available at times to experiment with. Although there are many online cloud alternatives, it is a lot more cost-effective for development purposes to run Kubernetes on a local bare-metal server, this is achievable on Linux by running the Xen hypervisor and this series of posts will walk you through its installation and configuration.

As you might have noticed from the updated link at the bottom, this blog is now running on Hugo, switching from Pelican implied mainly rewriting the custom templates I had, and making them output as close HTML as possible to the old ones in order minimize any CSS changes. Pandoc was also quite helpful to get the initial ReStructuredText to Markdown conversion done for the post contents, requiring mostly only fixes to hrefs and links in general.

I spent many years using stacking window managers and environments, from cde to mwm, fvwm, window maker, Gnome / KDE, and finally to Xfce. The past little while I kept hearing a lot about tiling window managers and since my typical desktop workspaces were pretty much always full of maximized windows, I figured I’d give i3 a try, so last year I switched and I haven’t looked back since.

For many years I have run a PS/2 keyboard switch between my two computers with no issues whatsoever, however PS/2 ports can be in fairly short supply these days, and after I last upgraded I had to move to a USB switch to be able to connect to my computer, and use a USB converter for my PS/2 keyboard to connect to the switch (I am typing this on an original Microsoft Natural Keyboard, still going strong since I bought it in 1995)
