aptitude -y install kvm qemu-kvm libvirt-bin virtinst bridge-utils

[2]	ブリッジネットワークを構成しておきます。

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
