Set-up of a VM with openSUSE tumbleweed for KDE development

Step 1: Installation of KVM on debian

I picked the GUI version:

sudo apt install virt-manager qemu-system libvirt-daemon-system qemu-utils
sudo usermod -aG libvirt,kvm <user>
sudo systemctl enable --now libvirtd

Step 2: set-up the openSUSE tumbleweed iso

1. Download tumbleweed here
2. start virt-manager
3. select QEMU/KVM
4. create new vm (pay attention to vm directory, RAM size, number of CPU cores and space (although the default 20GB should suffice))
5. ! warning ! I've ran into an issue that my vm suspended itself when I tabbed out before I started the installation process which caused the vm to crash to a point where it couldn't start the installation screen anymore. I am not sure whether that issue would have also come up if I would have tabbed out of the running installation process because I did not dare to. Caution advised.

Step 3: Getting everything inside the vm set-up

zsh

• for some (to me) unknown reason, chsh -s /usr/bin/zsh did not work. workaround: creating a new profile in Konsole and assigning zsh to it.
• typical zsh set-up. first downloading my .zshrc, then installing antigen into $HOME/.antigen/antigen.zsh

packages

• git is not pre-installed. Time to get to know zypper! It's just a package manager, nothing scary.
• mia-provided way of getting kde development libs and packages onto my system without much headache:
  1. sudo zypper ar -fr https://download.opensuse.org/repositories/KDE:/Unstable:/Frameworks/openSUSE_Factory/KDE:Unstable:Frameworks.repo
  2. sudo zypper ar -fr https://download.opensuse.org/repositories/KDE:/Unstable:/Applications/KDE_Unstable_Frameworks_openSUSE_Factory/KDE:Unstable:Applications.repo
  3. sudo zypper in -t pattern devel_kde_frameworks TODO: I have yet to understand, what the 3rd line is exactly doing and how 🥴

Step 4: Configuration

git

• git config --global user.name "firstname lastname" git config --global user.email "needs to be the same email as registered on bugs.kde.org"
  • I've also registered a separate email address just for this and generated a gpg key for it: gpg --generate-key (as usual) and then the super scary gpg --export-secret-keys -a <keyID> > filename.asc part for importing into thunderbird (delete filename.asc afterwards immediately!!!!!)
