test: /srv/result/host-info/2021-01-12/vm-2p8g/debian-sid-aarch64/z9.318111 /srv/result/host-info/2021-01-12/vm-2p8g/debian-sid-x86_64/z9.318142 /srv/result/host-info/2021-01-12/vm-2p8g/debian-sid-riscv64/z9.319551

[how] put public options like $kernel, $initrd, $smp together, set individual options like $machine, $bios, $nic according to different qemu command, then merge all options to run qemu.
