Guest: DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul  2 06:02:54 UTC 2026 x86_64
       (kernel built from /usr/obj/usr/src/sys/X86_64_GENERIC, clean-source snapshot)
Compiler: cc 8.3 [DragonFly] Release/2019-02-22
hw.model: QEMU Virtual CPU version 2.5+ ; hw.ncpu: 6 ; hz=100
kern.osreldate: 600519
NICs: vtnet0 lo0 (NO emx hardware present)
Module presence: /boot/kernel/if_emx.ko exists; `kldload if_emx` succeeds
(4    1 0xffffffff82600000    65000 if_emx.ko) but no emx interface attaches.
PCI: only QEMU-emulated Intel bridge/ISA/ATA chips (hostb/isab/atapci/none),
no e1000-class network device.
Emulation status: emx device-side code paths are hardware-gated on this guest;
verification is source-line-certain + protocol-replica/kernel-harness based
(same convention as the em(4) pass-2 family DF-3712..DF-3715).
