## Introduction
|
|
|
|
I know I already blogged about it in 2019 in [this article]({{< ref "qemu.md" >}}) 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
|
|
|
|
```sh
|
|
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,hostfwd=tcp::10022-:22
|
|
```
|
|
|
|
Connect to the console with a `vncviewer :0`, or if an ssh server is running, use `ssh -p10022 root@localhost`.
|
|
|
|
## Afterwards
|
|
|
|
```sh
|
|
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,hostfwd=tcp::10022-:22
|
|
```
