In RHEL8 the old network scripts have been deprecated. However, if you want you can addd them back in.

Red Hat have provided them in a package called network-scripts

$ sudo yum install network-scripts.x86_64

This adds all your favourite scripts back in

$ sudo rpm -ql network-scripts

Feedback welcome as always!

I’ve finally gotten around to installing RHEL8 as my primary desktop. One of my main use cases is to automatically build and configure vm’s using vagrant for testing.

A few things are subtly different on RHEL8, so I thought i’d share my learning (and some of the hacks i’ve put in place until I can investigate further).

Installation

Install Prerequisites

sudo yum -y install libvirt  \
                    libvirt-devel  \
                    ruby-devel  \
                    libxslt-devel \ 
                    libxml2-devel  \
                    libguestfs-tools-c  \
                    ruby-devel  \
                    gcc

Start the libvirt service

sudo systemctl enable --now libvirtd

Download packer into a Packer subdirectory (customise to taste)

mkdir ~/Packer
cd ~/Packer
curl -o ./packer.zip https://releases.hashicorp.com/packer/1.4.1/packer_1.4.1_linux_amd64.zip
unzip packer.zip

Download vagrant CentOS rpm (I’l probably tweak this later, but it works fine for now)

mkdir ~/Vagrant
cd ~/Vagrant
curl -o  vagrant_2.2.4_x86_64.rpm https://releases.hashicorp.com/vagrant/2.2.4/vagrant_2.2.4_x86_64.rpm

sudo yum install -y ./vagrant_2.2.4_x86_64.rpm

Install the vagrant libvirt plugin

CONFIGURE_ARGS='with-ldflags=-L/opt/vagrant/embedded/lib with-libvirt-include=/usr/include/libvirt with-libvirt-lib=/usr/lib' GEM_HOME=~/.vagrant.d/gems GEM_PATH=$GEM_HOME:/opt/vagrant/embedded/gems PATH=/opt/vagrant/embedded/bin:$PATH vagrant plugin install vagrant-libvirt

Test your vagrant project by specifying the provider

vagrant up --provider=libvirt

The following worked fine for me, let me know if you get any issues.
