KVM インストール2013/04/27 |
|
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 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:~#
