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? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru
