block: factory: Add disk image factory module

mirror of https://github.com/cloud-hypervisor/cloud-hypervisor.git synced 2026-08-05 02:19:16 +00:00

Introduce block::factory with open_disk() as the single entry point
for opening disk images. It handles file opening, format detection,
async I/O probing, and backend construction.

Per format helpers (open_fixed_vhd, open_raw, open_qcow2, open_vhdx)
prefer io_uring over AIO over synchronous fallback. Warnings only
fire when a backend was eligible but its runtime probe failed, not
when the user intentionally disabled it.
