# banger
Minimal Firecracker launcher.
## Requirements
- Linux host with KVM (`/dev/kvm` access)
- `sudo`, `ip`, `curl`, `ssh`
## Files
- `firecracker`: Firecracker binary
- `vmlinux`: guest kernel
- `rootfs.ext4`: guest root filesystem
- `id_ed25519`: SSH key for `root`
## Run
```
./run.sh
```
## SSH
```
ssh -i "./id_ed25519" root@<guest_ip>
```
## Shutdown
```
reboot
```
## Log Notes
- `PCI: Fatal: No config space access function found` and `MissingAddressRange` lines are expected with `pci=off` in `run.sh`.
- `SELinux: Could not open policy file ...` is expected in the minimal rootfs.
