FreeBSD – virsh serial howto<\/strong><\/h4>\n

Goal is to setup FreeBSD so you can connect to virtual serial port for login<\/p>\n

    \n
  1. \u00a0Add serials to KVM instance.\u00a0 Use Virtual Manager\n

    2. \u00a0In the virtual FreeBSD machine, edit the \/etc\/ttys\n
        \n
      1. Change the 3wire\/ ttyu0 to std.9600.<\/li>\n
