README.md

Installation

If you have a ubuntu iso you want to use then create the libvirt/vm folder and copy it there to ubuntu20_04.iso

mkdir ~/mirror-env/libvirt/vm
cp <ubuntu iso> ~/mirror-env/libvirt/vm/ubuntu20_04.iso

Note: the libvirt/vm folder and everything in it will be deleted by cleanup.yml

Prerequisites (debian)

Install QEMU and KVM

$ apt install --no-install-recommends qemu-system libvirt-clients libvirt-daemon-system

Install other packages for the playbook

$ apt install ansible cloud-image-utils dnsmasq ovmf python3

Packages I can't tell if you need or not

virtinst 
virt-manager
bridge-utils 

Then install virt-viewer for the ubuntu install using

$ apt install virt-viewer 

Finally add your user to the libvirt group (may need to logout for this to take effect)

usermod -a -G libvirt <username>

Prerequisites (archlinux)

needs update

$ pacman -S qemu libvirt virt-install virt-viewer ansible 

Running the Playbook

Modify the hosts file to your liking then run

ansible-playbook -K main.yml

Then connect to the created vm using virt-viewer

virt-viewer --connect qemu://system mirror

If vm is on a remote machine

virt-viewer --connect qemu+ssh://<user>@X.X.X.X/system mirror

Follow the steps under Installing Ubuntu before continuing


vm may stop so will need to start with

virsh start mirror

after starting check the ip address of the vm with

virsh net-dhcp-leases mirbr0

and ssh

ssh local@192.168.123.XXX

In the vm switch to root, install some packages, and clone the repo.

$ sudo su
password: password
$ cd
$ apt update && apt upgrade
$ apt install git ansible
$ git clone https://git.csclub.uwaterloo.ca/public/mirror-env.git

Then cd mirror-env/mirror and follow the README.md there.

Deleting the VM

The VM and everything related can be removed by running the cleanup.yml playbook

ansible-playbook -K cleanup.yml

Troubleshooting

virsh -c qemu:///system start mirror
virsh -c qemu:///system net-dhcp-leases mirbr0
net.ipv4.ip_forward = 1
modprobe kvm_intel

If running as root may need to edit config

# edit /etc/libvirt/qemu.conf
user = "root"
group = "root"
$ service restart libvirtd

Installing Ubuntu

  • user: local
  • password: password

The system created from following these steps should look like this:
