Title: Using QEMU as KVM
Date: 2021-09-14 22:59
Summary: Using KVM to run a Debian Live on SYS dedicated server
Category: Bloc-notes
Tags: debian, ovh, admin, shell, cli, vm, qemu
Status: Published
Slug: using-qemu-as-kvm
[_So You Start_ dedicated servers](https://www.soyoustart.com/fr/serveurs-essential/) did not provide [free KVM](https://www.soyoustart.com/fr/kvm-ip.xml) to run a random OS iso.
Let's try with [`QEMU`](https://github.com/qemu/qemu#readme) running an iso uploaded locally.
In _rescue mode_, download a live iso locally, install and run `QEMU`:
```bash
apt update && apt upgrade
apt install qemu-system-x86 vim
wget --no-check-certificate -O /tmp/installer.iso https://cdimage.debian.org/mirror/cdimage/release/current-live/amd64/iso-hybrid/debian-live-11.1.0-amd64-standard.iso
qemu-system-x86_64 -net nic -net user,hostfwd=tcp::80-:80,hostfwd=tcp::443-:443 -m 4096M -localtime -enable-kvm -hda /dev/sda -vnc 0.0.0.0:0 /tmp/installer.iso -boot d
```
