Hi again

According to my "ps aux" I see two getty with ttyS0 and ttyS1. 
Moreover I see /dev/issue welcome messages in my serial console but I still can’t write anythings, looks like console gives output only. 
I have tried with pty/udp/telnet on qemu side - all the same, only output. 

And just curios: 

Are there any news about publishing live migration stuff in seoul?
