Anaconda: can't resize VM serial terminal

bam · March 22, 2025, 9:33pm

If I boot Anaconda ISO in VM with serial console (console=ttyS0 kernel cmdline), I get only fraction of my real terminal size in tiny TMUX window (24x80) when Anaconda starts.

I tried to solve it by running this helper in guest, but no luck:

github.com/akkana/scripts

termsize

master

#!/usr/bin/env python

# Get the current size of the terminal window, and set stty size accordingly.
# A replacement for xterm's resize program, with no X dependency.
# Useful when logged in over a serial line.

import os, sys
import fcntl
import struct
import time
import re
import tty
import termios
import select
