KVM インストール2011/04/30

  KVM ( Kernel-based Virtual Machine ) +QEMU での仮想化です。 搭載しているCPUが仮想化機構( Intel VT 等 )を備えている必要があります。

[1] まずは必要なもののインストールです。
root@dlp:~#
aptitude -y install kvm qemu-kvm libvirt-bin virtinst bridge-utils
[2] ネットワーク仮想化のオーバーヘッドを減らすことができる vhost-net を有効にしておきます。
root@dlp:~#
modprobe vhost_net

root@dlp:~#
lsmod | grep vhost

vhost_net     27606 0
root@dlp:~#
echo vhost_net >> /etc/modules

[3] ブリッジネットワークを構成しておきます。
root@dlp:~#
vi /etc/network/interfaces


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# 以下のように変更

auto eth0
iface eth0 inet manual

#
iface eth0 inet static
#
address 10.0.0.50
#
network 10.0.0.0
#
netmask 255.255.255.0
#
broadcast 10.0.0.255
#
gateway 10.0.0.1

# ブリッジインターフェース設定追記

iface br0 inet static
address 10.0.0.30
network 10.0.0.0
netmask 255.255.255.0
broadcast 10.0.0.255
gateway 10.0.0.1
bridge_ports eth0
bridge_stp off
auto br0


root@dlp:~#
ifdown eth0 && ifup br0 && ifup eth0
