-## Testing in a VM (KVM)
-A simple way to test locally in a virtual machine using libvirt + KVM:
-
-    $ sudo virt-install -n web01 -r 1024 --vcpus 2 \
-    -l http://ubuntu.mirror.ac.ke/ubuntu/dists/trusty/main/installer-amd64/ \
-    --os-type=linux --os-variant=ubuntusaucy \
-    --disk /var/lib/libvirt/images/web01.qcow2,device=disk,bus=virtio,format=qcow2,size=40 \
-    --vnc --cpuset=1,2 -x "auto=true priority=critical url=https://help.ubuntu.com/lts/installation-guide/example-preseed.txt"
-
-This boots from a network Ubuntu mirror, then uses a preseed to automate the OS installation.
-
-## Testing in Vagrant
-Not as simple as on GNU/Linux with KVM, but still easy:
-
-    $ vagrant up
-
-A new VirtualBox VM will come up with the IP `192.168.33.10`.
