packer rhel9 qemu

packer using qemu builder to create golden images locally.

What is this repository?

This repository is for who may want or need create rhel9 golden images with qemu. And when i was searching for repos like this, there were just a few, and some of them, the boot command dindt work very well causing kernel panic.

About the code

The code is very simple, the purpose of this repo is to warn about some mistakes you can get.

1 - You need qemu args to build the image, for some reason just the flag cpu is required.

2 - If boot command is wrong, probaly it will cause kernel panic.

3 - If your ssh_username and ssh_passwd are incorrect, packer will not create the output (image) so make sure they are corret in the kickstart file

Required:

• Kvm
• virt-install
• rhel 9 iso and checksum
• packer

Setup

this is just if you need

apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-bin bridge-utils

sudo lsmod | grep kvm

sudo kvm-ok

Run

packer validate .

PACKER_LOG=1 packer build rhel9.pkr.hcl or

packer build rhel9.pkr.hcl

Run image with virt-install

virt-install --name rhel9custom --memory 2048 --vcpus 2 --disk rhel9-kvm.qcow2,bus=sata --import --os-variant rhl9 --network default

convert img

sudo qemu-img convert -f qcow2 rhel9-kvm.qcow2 rhel9custom.vdi

im not using variables in this project because its a local build
