Oracle VM 2.x では、標準で virt-installコマンドが導入されており、Dom-0のCUIで新規VMを作成できました。
virt-installコマンドは、GPLライセンスで配布される Virtual Machine Managerプロジェクト http://virt-manager.org/ の一部であり、内部的にlibvirtライブラリを使用しています。
しかし、Oracle VM 3.xでは、標準でvirt-installコマンドが導入されていません。
もちろん、Oracle VM Managerを使用すれば新規VMを作成できますが、作業の効率化、テンプレート化の ためにCUIでの新規VM作成を行いたい。ということで、virt-install をインストールしてみます。 (virt-installを使用しない方法もありそうですが・・・とりあえず使ったことがあるvirt-installを使用する方向としてます）
注意! 本エントリでは、サポートされない手順について記載しています！ ⇒ KROWN:158258 OracleVM 3 での Oracle VM Server コマンドラインから許可されている操作(※:参照にはサポート契約が必要)

しかし、インストールしただけではvirt-installは使用できないようです。
[root@csov3s99 ~]# virt-install

メカニズムは調べ切れていませんが、Xenデーモンの xend-unix-server 機能を有効にする必要があるようです。

virt-installでインストールしたVMをxm shutdownしたところ、xm list にエントリが残る現象が確認できました。
[root@csov3s01 ~]# xm list

dummy_vmname 4096 2 0.0←★xm destroyを実行しても消えません

残る場合と残らない場合があるようで、明確なところはわかっていませんが、
virsh undefine dummy_vmname を実行するとエントリが消えました。
おそらくlibvirtd側の管理情報が残っている状態なのだと思われます。
