qemu-system-x86_64 -m 2048 -smp 2 -chardev
socket,id=SOCKSYZ,server,nowait,host=localhost,port=46514 -mon
chardev=SOCKSYZ,mode=control -display none -serial stdio -no-reboot
-name VM-test -device virtio-rng-pci -enable-kvm -cpu
host,migratable=off -device e1000,netdev=net0 -netdev
user,id=net0,restrict=on,hostfwd=tcp:127.0.0.1:28993-:22 -hda
bullseye.img -snapshot -kernel bzImage -append "root=/dev/sda
console=ttyS0 net.ifnames=0 biosdevname=0"

serial is via stdio, and in normal boots I get the bootlog in the
terminal, but in this case there was nothing.
