QEMU is now run from the hostos resolver, so an Oracle Linux host uses
/usr/libexec/qemu-kvm. The orphan scan, node-reset.sh, reset-dev-env.sh,
run-bench.sh and the e2e harness all treat qemu-kvm as a guest process.
System instances boot qboot passed with -bios. build-qboot.sh builds it from
a pinned upstream commit in a digest-pinned container; the output matches
Debian 13's qboot.rom byte for byte. The tarball ships it with its licence
and releases publish the source. The daemon refuses a launch without it, and
spx admin preflight flags a QEMU with no microvm machine or a missing qboot.
reset-dev-env.sh's pkill -x qemu-system-x86_64 never matched a truncated
comm; it now uses node-reset.sh's owner-scoped match.
