Introduction

I know I already blogged about it in 2019 in this article but it is good to refresh one’s memory for something so useful. No virt-manager or any other gui required, no complicated networking… It’s easy!

Installation

qemu-img create -f raw alpine.raw 16G
qemu-system-x86_64 -drive file=alpine.raw,format=raw,cache=writeback \
                   -cdrom Downloads/alpine-virt-3.14.0-x86_64.iso \
                   -boot d -machine type=q35,accel=kvm \
                   -cpu host -smp 2 -m 1024 -vnc :0 \
                   -device virtio-net,netdev=vmnic -netdev user,id=vmnic

Connect to the console with a vncviewer :0.

Afterwards

qemu-system-x86_64 -drive file=alpine.raw,format=raw,cache=writeback \
                   -boot c -machine type=q35,accel=kvm \
                   -cpu host -smp 2 -m 1024 -vnc :0 \
                   -device virtio-net,netdev=vmnic -netdev user,id=vmnic
