Or should one of those change if I don't want to run a desktop-optimized kernel on my servers?
Or is there now no difference in either included features or performance?
Or are the differences now all run-time or boot-time configurable?
Mostly new boxes are x86_64 only of course, but I have some still fairly relevant boxes (out there in remote colo facilities where it's costly and time consuming and generally a non-trivial project to replace them) that have 32bit xeon's that I neither want to throw away nor leave on old OS versions nor run on a desktop kernel, although updating the to 11.3 or 11.4 and leaving them there until I am ready to junk them might not be too bad since they aren't exactly new anymore either. There are also (admittedly atypical) workloads that are faster in 32bit mode even on the latest hardware. There are also appliances using perfectly current 32bit cpus and vm's that don't need >4G inside the vm. "oldhardware" is a cavalier, broken, and inconsiderate assumption as the only possible use of 32bit code or even non-pae 32bit code today.

I wonder why kernel-default is not chosen.kernel-desktop is the default kernel for x86_64, kernel-default is for i586
The installation is a VBox machine. Perhaps that's why?
I'll try on real HW next.
without pae
We considered a rename of kernel-default to kernel-oldhardware, but
decided not to.
Greetings, Stephan
