QEMU in a terminal
When I use text only VMs I usually find more convenient to just work from terminal. After a bit of research I found the perfect solution for me.
Inside your guest system edit
/etc/default/grub to start a serial console on
/dev/ttyS0 and disable GRUB graphical terminal:
Then update GRUB.
/etc/inittab and enable login on the serial console. On Devuan you
just need to uncomment this line:
T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
Serial console however can't dynamically adjust to your terminal resolution. Luckily I found a solution on StackExchange.
After setting up your guest you can now use your VM directly from your terminal
emulator, just append
-nographic to your QEMU options.
