KVM Virsh: Redirect FreeBSD Console To A Serial Port

To redirect the console of a FreeBSD guest operating system running on KVM to a serial port, you will need to perform the following steps:

1. Edit the guest's configuration file to specify the serial port as the console. The configuration file is typically located at /etc/libvirt/qemu/<guest>.xml.

2. Add the following line to the <devices> section of the configuration file:

<console type='pty'>
  <target type='serial' port='0'/>
</console>

3. Restart the guest using the virsh command:

virsh destroy <guest>
virsh start <guest>

4. Connect to the serial port using a terminal emulator program such as minicom or screen. The serial port will be located at /dev/ttyS0 (if it is the first serial port).

minicom -D /dev/ttyS0

5. You should now be able to see the output of the FreeBSD guest's console on the terminal emulator program.

Note: The steps above assume that the host operating system is Linux. If you are using a different host operating system, the path to the serial port and the command to connect to it may be different.
