This is a simple tool to generate testing networks of virtual machines. It was
written primarilly for my bachelor's thesis, which lives at <https://gitea.ledoian.cz/LEdoian/bc_thesis>.
# Usage:
1. Edit `gen_machines.py` to define the desired network
2. Optionally edit the templates of config files in the `templates/` folder
3. Run `gen_machines.py`
4. Create pre-installed Alpine Linux 3.15.4 disk image in `dummydisk.img`
- you can use `gen_dummy.sh` for that
- To automatically install alpine, `alpine_install` can be used as the install script. See comment in that file for explanation
- After installation, `alpine_postinst` sets up the SSH key and add basic packages.
5. Run `gen_disks.sh` as root – this creates customized disk images for all the machines
6. Append `output/bridge.conf` to your `/etc/qemu/bridge.conf` in order to be able to connect your VMs to bridges as regular user
7. Run `output/gen_bridges.sh` to create the bridge interfaces on your machine.
Now, the machines may be started. Either use `qemu.sh` script in the respective
directory under `output/`, or run `./manage_all.sh start`. To attach, use SPICE
on the `spice.sock`, or SSH there using the key in this repo, if you already
have connectivity.
Loging in as root should not ask for password.
