# Qubes Mirage Firewall
|
||
|
|
|

|
|
Ensures the Mirage firewall kernel VM is installed in dom0
|

|
|
|

|
|
## Overview
|
||
|
|
|
||
|
|
This script first ensures the TemplateVMs are updated and then downloads the Mirage firewall. It configures
|
||
|
|
Mirage firewall so it can be used as a unikernel firewall VM.

### Update TemplateVMs
|
||
|
|
logg info 'Updating TemplateVMs via `qubesctl`'
|
||
|
|
timeout 900 qubesctl --show-output --skip-dom0 --templates state.sls update.qubes-vm
|
||
|
|
|
||
|
|
### Ensure mirage-firewall kernel folder setup
|
||
|
|
if [ ! -d /var/lib/qubes/vm-kernels/mirage-firewall ]; then
|
||
|
|
logg info 'Creating the /var/lib/qubes/vm-kernels/mirage-firewall directory'
|
||
|
|
sudo mkdir -p /var/lib/qubes/vm-kernels/mirage-firewall
|
||
|
|
fi
|
||
|
|
|
||
|
|
### Install the mirage-firewall kernel
|
||
|
|
if [ ! -f /var/lib/qubes/vm-kernels/mirage-firewall/vmlinuz ]; then
|
||
|
|
logg info 'Downloading the pre-compiled mirage firewall kernel in the {{ .qubes.provisionVM }} VM'
|
||
|
|
qvm-run provision 'curl -sSL {{ .qubes.mirageUrl }} > ~/Downloads/mirage-firewall.tar.gz && tar xjf ~/Downloads/mirage-firewall.tar.gz -C ~/Downloads'
|
||
|
|
logg info 'Transferring mirage-firewall kernel to dom0 from the {{ .qubes.provisionVM }} VM'
|
||
|
|
qvm-run --pass-io {{ .qubes.provisionVM }} 'cat /home/user/Downloads/mirage-firewall/vmlinuz' > /var/lib/qubes/vm-kernels/mirage-firewall/vmlinuz
|
||
|
|
fi
|
||
|
|
|
||
|
|
### Create dummy initrmfs for the mirage-firewall kernel
|
||
|
|
if [ ! -f/var/lib/qubes/vm-kernels/mirage-firewall/initramfs ]; then
|
||
|
|
logg info 'Adding dummy initrmfs file to the mirage-firewall kernel folder'
|
||
|
|
gzip -n9 < /dev/null > /var/lib/qubes/vm-kernels/mirage-firewall/initramfs
|
||
|
|
fi
|
||
|
|
{{ end -}}
|
||
|

```
