Can a stock kernel with all the probing still intact ever perform as well as a custom one with all the non relevant stuff stripped out? Subsecond pod starting is very handy.
It's an interesting question; hopefully it can get close if we: a) Configure the virtual hardware appropriately b) Pass kernel command line options to tell the probes to get out of the way c) Maybe pass firmware/ACPI data for the same type of thing. (Not investigated) Dave

Thanks for sharing your experiments. Your approach to integrate Kata shows some points improve to support this use case.
I did not consider in the past use the host kernel as the kata kernel but definitely is a use case we could support.
A couple of questions related on how to mange the kernel and image when you add Fedora RPMs.
Lokesh is working on Fedora RPMs. I will leave the questions to Lokesh, except to say that reusing kernel and QEMU packages is attractive because it means fewer builds, fewer packages, and a smaller test matrix.
Are you going to add a symlink to allow the kata runtime always find the latest installed kata kernel ?
How are you planning to update the modules if a kernel changes ? The image will by generated after a new kernel update? Or every time the kernel changes you are going to update the kernel from package?
