= 【libvirt 介紹】 =
 * libvirt 支援各種 VMM 程序(Xen, KVM, VirtualBox, Qemu, OpenVZ, UML, LXC...)，以提供統一的虛擬化上層管理介面

 * libvirt 有兩種運作模式：
   1. '''local''': 直接使用 libvirt API [[BR]] [[Image(http://www.ibm.com/developerworks/cn/linux/l-libvirt/figure1.gif)]]
   2. '''Remote''': 必須額外啟動 libvirtd 來 remote communication [[BR]] [[Image(http://www.ibm.com/developerworks/linux/library/l-libvirt/figure2.gif)]]

 * [http://libvirt.org/html/libvirt-libvirt.html libvirt API 主要可分為五種類型：]
   1. VMM 連接 API
   2. Domain 管理 API
   3. 網路管理 API
   4. Storage volume API
   5. Storage pool API

 * [http://libvirt.org/bindings.html libvirt API 支援的語言]
   * python
   * C/C++
   * Ruby
   * JAVA
   * perl
   * variety of scripting languages, and even a unified functional language (Objective caml)

 * 使用 libvirt 開發的應用
   * virt-install
   * virt-clone
   * virt-manager
   * virt-viewer
   * oVirt

== [安裝] ==
 * [http://libvirt.org/deployment.html 從 source 安裝]
{{{
$ wget http://libvirt.org/sources/libvirt-0.8.4.tar.gz ; tar zxvf libvirt-0.8.4.tar.gz ; cd libvirt-0.8.4
$ ./configure --with-xen --prefix=/usr
$ make
$ make install
}}}
   * configure 遇到缺少某套件時
{{{
$ sudo aptitude install libxml2-dev libgnutls-dev libdevmapper-dev libxen-dev
}}}
 * 從套件檔安裝

== [操作] ==
 * 使用 virsh (虛擬 shell，基於 shell 的互動方式操作)
{{{
# virsh create xen-vm01.xml
(設定檔為 xml 格式)

# virsh list
# virsh suspend 1
# virsh resume 1
}}}

== [使用 API] ==
