VMware Fusion on Mac OS X環境にて、vMXソフトウェアルータをセットアップした備忘録です。

MacBook Pro (Retina, 15-inch, Mid 2015)
プロセッサ： 2.2 GHz Intel Core i7
メモリ：16 GB 1600 MHz DDR3

基本的には、"vMX Getting Started Guide for KVM"の記載に従って、vMX環境を整備しました。

■ vMXトライアル版の入手

次のURLから、vMXトライアル版をダウンロードします。
http://www.juniper.net/us/en/dm/free-vmx-trial

たぶん、ここの工程が、一番難易度が高いのかもしれません

■ vMXのセットアップ備忘録

最小構成となる、"Lab simulation"環境のセットアップを目指します。

次なる難関は、最小構成といえども、4CPU, 5GB (+数GB)の仮想インスタンスが必要になる点ですね
（ちなみに、今回は、4CPU, 8GBの仮想インスタンスで作業を進めました。）

(1) Ubuntu環境確認

VMware Fusion上に、仮想インスタンス"Ubuntu Server版 16.04.1"をデプロイしました。

Ubuntuバージョンの確認

$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.1 LTS"

搭載nicの確認

$ lspci|grep Ethernet

02:02.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
02:03.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)

network設定の確認

$ cat /etc/network/interfaces

# and how to activate them. For more information, see interfaces(5).

(2) vMXインストールに向けての事前準備

各種パッケージのインストール

$ sudo apt-get update
$ sudo apt-get install -y bridge-utils qemu-kvm libvirt-bin
$ sudo apt-get install -y libyaml-dev python-yaml numactl libparted0-dev libpciaccess-dev
$ sudo apt-get install -y libnuma-dev libyajl-dev libxml2-dev libglib2.0-dev

libvirtのバージョン確認

$ libvirtd --version
libvirtd (libvirt) 1.3.1

virtshのバージョン確認

$ virsh --version

(3) Ubuntu環境の設定変更

KSMを無効にする

qemu-kvm

KSM_ENABLED=0

APICを無効にする

$ sudo vi /etc/modprobe.d/qemu-system-x86.conf

qemu-system-x86.conf

options kvm_intel enable_apicv=0 nested=1 enable_apicv=0

再起動 ..

$ sudo reboot

"kvm-intel"カーネルモジュールを組み込む

$ sudo modprobe kvm_intel

$ lsmod|grep kvm
kvm_intel             172032  0
kvm                   536576  1 kvm_intel
irqbypass              16384  1 kvm

以上、vMXの初期セットアップが、完了できました。

■ 最後に

そもそも、MacBook Proに、vMXソフトルータをセットアップするのは、無謀なチャレンジでした。
本来、Intel Xeon搭載のマルチコアCPUを多数搭載しているサーバ / ワークステーションに、セットアップするべきでした。
ただ、セットアップ作業は、だいぶ熟知できたので、今後、新たなサーバ入手する機会があれば、本格的に、vMXソフトウェアルータの検証を行ってみたいです。
