I will create multiple content related to qemu/kvm/libvirt, then this post is to use as reference.

tasks⌗

  1. install OS (using debian netinstall)
  2. install virtualization tools
  3. modify main network to use as bridge

1. install OS (using debian netinstall)⌗

  • I usually go with fedora server but, I need different distribution because there is an error with ssh and Terraform/Pulumi. [1], [2], [3]
  • Ubuntu is using netplan (+ snap) and I just need a hypervisor, then debian is my choice

[1], [2], [3]

2. install virtualization tools⌗ 

cat /proc/cpuinfo |grep -E "vmx|svm"

apt install qemu-kvm libvirt-daemon-system cockpit cockpit-machines

reboot

3. modify main network to use as bridge⌗ 

apt-get install bridge-utils -y

cp -a /etc/network/interfaces ~/
vi /etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

# Specify that the physical interface that should be connected to the bridge
# should be configured manually, to avoid conflicts with NetworkManager
