QEMU Disk Bus Mismatch Breaks Ubuntu 26.04 Boot
A developer found that Ubuntu 26.04 images fail to boot in QEMU when using the -hda disk bus instead of virtio-blk. The newer images boot initrdless and rely on PARTUUID, which requires the virtio driver. Older images used an initrd with MODULES=most, supporting both buses.

This is a niche but instructive case of how upstream kernel changes can silently break virtualization workflows.
