What's new in QEMU land?
summary
QEMU 7.1–8.0 adds concrete features: LoongArch64 full-system and user-mode support with example kernels and initrds, zero-copy send migration (requires locked memory on Linux) which cuts host CPU by skipping page copies, new netdev stream backends with address-type=unix to tunnel guest traffic over Unix sockets, user-mode x86 binaries now default to the maximum CPU model (newer SSE requirements), replacement of legacy -soundhw by unified -audio pa,model=sb16, and removal of the old webiofs daemon in favor of a Rust reimplementation.
