--- Comment #3 from David NewHamlet <wheelcomplex at gmail.com> ---
this still stay with FreeBSD-12.0-CURRENT-amd64-20180315-r331001-disc1.iso
under Ubuntu 18.04 X86_64(Linux lxn550jk 4.15.0-10-generic #11-Ubuntu SMP Tue
Feb 13 18:23:35 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux).

Ubuntu package info:
qemu-system-x86 1:2.11+dfsg-1ubuntu4  amd64 QEMU full system emulation binaries
(x86)

I have try some tips from
https://forums.freebsd.org/threads/freebsd-10-does-not-boot-kvm-kernel-trap-12.47409/
but it still not works.
