libvirt users - Nov 2018 - Re: console type tcp with logging

Hi! I want to have ability to connect to guest console via libvirt api
(and expose this data to xtermjs via websocket) with getty tty. And
also i want to have log of tty1 (do log grub, kernel booting and
errors).
What i need to do in libvirt xml for such case?

XML is described here

https://libvirt.org/formatdomain.html#elementsConsole

In particular regardless of what backend type you use for the
seral port, you can add logging using

  <log file="/var/log/libvirt/qemu/guestname-serial0.log"
append="off"/>

Daniel
