Introduction

FreeNAS 9.10 is based on FreeBSD 10.3 and as such, supports the BSD hypervisor bhyve. There are different frontends for bhyve, one of them is iohyve which is included in FreeNAS 9.10. This document describes how to setup iohyve for operation on FreeNAS 9.10 and basic VM management tasks.

Setting up Iohyve

Iohyve is already installed in FreeNAS 9.10, so it only needs to be enabled. This is done by adding the following lines to /conf/base/etc/rc.conf:

iohyve_enable="YES"

iohyve_flags="kmod=1 net=igb0 pool=storage-volume"

From the Archives: Code Quarterly's 2011 Q&A with Rich Hickey

Rich Hickey is frequently quoted as saying:

You can reach a point with Lisp where, between the conceptual simplicity, the large libraries, and the customization of macros, you are able to write only code that matters. And, once there, you are able to achieve a very high degree of focus, such as you would when playing Go, or playing a musical instrument, or meditating. And then, as with those activities, there can be a feeling of elation that accompanies that mental state of focus.

Vagrantfiles for testing configuration management (Ansible).

Overview

Configuration management that runs over SSH, namely Ansible, benefits in having test machines available on the network. The enclosed Vagrantfiles provide multiple virtual machines to run as guests on the developer's machine. The guests appear as hosts on the LAN, providing a local ephemeral cloud.

The virtual machines here are similar, but different. One provides **Ubuntu
