Just how do I connect a serial terminal to a KVM instance?

Probably I'm misconstruing what KVM can, yet the capacity to add/remove hardware on the VM appears to indicate I can add a serial port that after that works as a terminal.

So, my inquiries are:

  1. Which setups are best for the visitor FreeBSD circulation? (There are several!)
  2. Just how do I accessibility claimed terminal from my Linux host?

Well, you need to mimic a serial port within the emulator certainly and also have that come on the host. The visitor OS need to place something on its 'equipment serial port' like a login punctual using as an example, getty_ps. Currently I directly have not needed to utilize it in this manner. Primarily the mimicked serial port on the visitor OS is made use of for debugging details (Haiku still makes use of that by default) and afterwards it is recorded by the emulator (like VMware) as a straightforward message - documents to have the debug details readily available. I'll attempt below to get something working on the mimicked serial console within qemu.

I can currently address my very own inquiry based upon Stefan's comment and also both connected write-ups :

Here is the remedy :

  • You require not modify anything to do with the host arrangement gave it has the default serial tool indicating pty therein.
  • Make certain the boot parameter for your bit has this added : serial=tty0 console=ttyS0,115200n8. Generally attained by editing and enhancing /boot/grub/menu.lst
  • Configure /etc/inittab and also add the line T0:S12345:respawn:/sbin/getty -hL ttyS0 115200 vt100 to release a getty and also offer you the login punctual.

I can validate this benefits me making use of a fedora system (albeit I did need to set enforcing=0 as an added parameter due to the fact that the system concerned is fedora rawhide running SELinux MLS).

I assume from there I can possibly exercise just how to do the very same for freebsd.

Many thanks Stefan!
