Thanks, Thomas.

I tried virtio-serial-pci. I was able to boot the VM without an error.
I ran telnet like 'telnet localhost 6666' in the host, but it didn't
seem like printing anything or taking any input.

$telnet localhost 6666
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

I'm using QEMU v2.11.0

Thanks,
Jintack
