QEMU has no ~~GUI~~, but what if you want to use the command-line? Then this is for you!

QEMU has no virtual machine manager (but virt-manager and GNOME boxes are good ones), but what if you want to use the command-line? Then this is for you!

QEMU has many arguments, but here's a basic example of usage of the AMD64 softmmu (targeted for modern QEMU and modern linux)<nowiki>:</nowiki>

<code>qemu-system-x86_64 -~~hda~~ alpine.~~qcow2~~ -~~cdrom~~ alpine.~~iso~~ -~~vga~~ virtio -~~boot cd~~ -usb -device usb-tablet -~~display gtk~~</code>

<code>qemu-system-x86_64 -M pc -cdrom .\alpine.iso -boot cd -drive if=virtio,file=alpine.qcow2 -m 1G -accel tcg -device virtio-vga,edid=on,xres=800,yres=600 -usb -device usb-tablet -net user,hostfwd=tcp::8022-:22 -net nic,model=e1000</code>

You need to create the disk image using the following command<nowiki>:</nowiki>

<code>qemu-img create -f qcow2 alpine.qcow2 30G</code>

After that, download alpine linux [https://alpinelinux.org/downloads/ here]. Choose the Standard or Virtual variant, and choose x86_64. After downloading the image, rename it to "alpine.iso"

After that, just run QEMU, using the command-line arguments from the command-line example from above

After that, just run QEMU, using the command-line arguments from the command-line example from above. Use openssh or dropbear as the ssh server

After installing alpine linux, you're done! No KVM was needed!

After installing alpine linux, you're done! No KVM was needed! To connect to the shell from ssh, run <code>ssh root@localhost -p 8022</code> or <code>ssh user@localhost -p 8022</code> on the host system (the second ssh command example requires a user with the name of <code>user</code>, and the first ssh command example requires running <code>setup-alpine</code> again, and saying "yes" when it asks to allow root login)
