# ubuntu-fan-hacks

Some notes for experimenting with the `ubuntu-fan` package.

## Network bridge

Create a network bridge for the fan VMs

```xml
$ virsh net-dumpxml fan

fan
fedc1cbe-5ae1-4d7c-937e-4d79252fb98e

```

## Make hostnames resolvable

Add this on the VM host machine:

```
$ cat /etc/NetworkManager/dnsmasq.d/fan.conf
server=/fan/172.30.0.1
```

## Create NoCloud config drives for each VM

```bash
for i in 1 2 3 ; do ./create-config-drive -h fan-vm-${i} -k ~/.ssh/id_rsa.pub -u ./user-data fan-vm-${i}-config.iso; done
```

Note: I copied and modified create-config-drive (missing attribution
because I don't recall where).

## Copy config drives for libvirt access

```bash
sudo cp -v fan-vm*-config.iso /var/lib/libvirt/images
```

## Create the VMs
```bash
./setup-vm.sh 1 2 3
```

## Verify VMs are running

This will take a little time because of cloud-init installing packages
and updates, et al.

```
$ virsh list
Id Name State
----------------------------------------------------
27 fan-vm-1 running
28 fan-vm-2 running
29 fan-vm-3 running
```

# /usr/sbin/fanatic testing

## Docker images (including network utilities)

```
$ docker pull frobware/ubuntu
$ docker tag frobware/ubuntu ubuntu
```

We tag that as `ubuntu` so that `fanatic` will just work. The
`frobware/ubuntu` image has the following networking utilities
installed:

```
apt-get -y update
apt-get -y install iputils-ping traceroute net-tools iproute2
```
