Ixia VMon Cisco Modeling Lab (CML)Akira Iwamoto
Cisco Systems
Cisco Modeling Lab• シスコが提供する仮想ネットワークシミュレーション環
境• vIOS, IOS XRv, CSR 1000V 等を自由に接続し、テスト
する事が可能• OpenStack 経由で、ルータ OS が KVM 上で動作する

Third-party virtual machine• Q. Can customers run third-party virtual machines in
Cisco Modeling Labs? • A. Third-party virtual machines should work if compiled to
run on Linux kernel-based virtual machines; however, features of Cisco Modeling Labs, such as auto configuration, are designed for Cisco virtual operating systems only. Cisco TAC support does not answer questions in regard to third-party virtual machines or their interworking with the software.

サードパーティ VM を組み込んでも良い？
いいけど、サポートはしませんよ
自己責任で！
Ixia VM (IxVM)• Ixia 社が販売するネットワークトラフィックテスターの
Virtual Machine 版• OVA ファイルで提供され、 CentOS や SUSE Linux 上
で動作する

OVA ファイルを追加 • OVA ファイルは tar ファイル
• VMDK ファイルを取り出す• tar xfv VM_IxVM-centos6.3-2.0.0.402.ovaVM_IxVM-centos6.3-2.0.0.402-disk1.vmdk
• Pkg ファイルを作成する• Kvm の起動オプションに使用される• IxVM は scsi を使用するため、ディスク設定を変更
