Mirror Env

This script helps quickly set up a vm development environment for cs club's mirrors.

VM Installation Option 1 (qmeu-vm.yml)

instructions need to be rewritten

Install the following dependencies

qemu
genisoimage
ovmf (find the location of OVMF_CODE.fd, it is system dependent)

Edit the configuration variables in the script file to reflect your system.

The mirror-vm script will will automatically install ubuntu using the autoinstall feature.

curl -O https://releases.ubuntu.com/20.04/ubuntu-20.04.2-live-server-amd64.iso
$ ./mirror-vm create
$ ./mirror-vm run-install

To view the vm, you also need a vnc viewer. TigerVNC is a good choice. Simply run

$ vncviewer :5900

Due to the way the ubuntu autoinstall is designed, user confirmation is required to start the autoinstallation process. Enter yes when prompted with this line:

Continue with autoinstall (yes|no)

After going through the install process you can run the vm with

$ ./mirror-vm run

The default login user has

username: ubuntu
password: ubuntu

Run Playbook

ansible-playbook qemu-vm.yml

VM Install Option 2 (kvm)

Install Packages (debian)

$ apt install qemu-kvm libvirt virt-install virt-viewer ansible

Install Packages (archlinux)

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

Run Playbook

ansible-playbook kvm-vm.yml

Post-Installation

The ubunutu autoinstall can only handle basic installation. We require a more powerful tool to configure the post-install environment. For this reason, we will be using ansible.

First, install ansible and sshpass. Perform all the following commands in the post-install/ directory.

Also install the extra roles

$ ansible-galaxy install -r requirements.yml

Check that ansible can talk to the vm:

$ ansible -m ping all

We can now complete the rest of the post-install with

$ ansible-playbook -K playbook.yml

Drives vda and vdb are for the main filesystem, they use raid1. Drives vdc, vdd, vde and vdf are in a raidz2 zpool.
