## Deploy
If you want to deploy manually, unpack `mirage-firewall.tar.bz2` in dom0, inside `/var/lib/qubes/vm-kernels/`. e.g. (if `dev` is the AppVM where you built it):
If you want to deploy manually, unpack `mirage-firewall.tar.bz2` in domU. The tarball contains `vmlinuz`,
which is the unikernel itself, plus a couple of dummy files that Qubes requires:
[tal@dom0 ~]$ cd /var/lib/qubes/vm-kernels/
[tal@dom0 vm-kernels]$ qvm-run -p dev 'cat qubes-mirage-firewall/mirage-firewall.tar.bz2' | tar xjf -
[user@dev ~]$ tar xjf mirage-firewall.tar.bz2
The tarball contains `vmlinuz`, which is the unikernel itself, plus a couple of dummy files that Qubes requires.
Copy `vmlinuz` to `/var/lib/qubes/vm-kernels/mirage-firewall` directory in dom0, e.g. (if `dev` is the AppVM where you built it):
[tal@dom0 ~]$ mkdir -p /var/lib/qubes/vm-kernels/mirage-firewall/
[tal@dom0 ~]$ cd /var/lib/qubes/vm-kernels/mirage-firewall/
[tal@dom0 mirage-firewall]$ qvm-run -p dev 'cat mirage-firewall/vmlinuz' > vmlinuz
Finally create dummy files required by Qubes OS:
[tal@dom0 mirage-firewall]$ touch modules.img
[tal@dom0 mirage-firewall]$ gzip -n9 < /dev/null > initramfs
Run this command in dom0 to create a `mirage-firewall` VM using the `mirage-firewall` kernel you added above:
