QEMU/KVM virtual machines on linux

I'm running Debian linux 12 on macbook pro.

I find the official Debian Wiki is as always very useful:

KVM - Debian Wiki

and also this Youtube video tutorial for beginners:

QEMU/KVM for absolute beginners by Veronica Explains

install needed packages

%sudo apt install --no-install-recommends qemu-system libvirt-clients libvirt-daemon-system

%sudo apt install virtinst #if you want to create guest os on command line instead of gui

Creating a new guest:

virt-install --virt-type kvm --name bullseye-amd64 \
--location http://deb.debian.org/debian/dists/bullseye/main/installer-amd64/ \
--os-variant debian11 \
--disk size=20 --memory 4000 \
--graphics none \
--console pty,target_type=serial \
--extra-args "console=ttyS0"

Connect to a VM through command line

#Use the virsh console command to log in to a running VM called ‘centos7’ type: 

%virsh console centos7 

#To exit a virsh console session, type 

CTRL + Shift + ]
