Thanks for sharing.  I don't have a K3 CoM260 myself, but some folks on
the Fedora RISC-V Matrix have it.

Looking through your wiki, I see you have an elaborate script for the
KVM part.  At first, the name of the script tricked me
('k3-run-fedora-guest.sh').  From quick skimming, I see it is handling a
lot more than just "running" the guest. It handles the entire guest
lifecycle management with plain QEMU, w/o libvirtd, QMP socket
validation, `flock` syscall handling, qcow2 backing file format
validation (a good security instinct :)) and more.
