個人的な趣味による Nutanix Community Edition 日記。Japanese のみですみません。

Nested Nutanix CE で Multi-Node Cluster の Open vSwitch に Bridge / Bond port を追加してみる。

複数の NIC がある Nutanix CE で、Open vSwitch に Bridge を追加してみます。Prism の Web UI からだと設定できないので、CVM にログインして CLI を使用します。

  • Bridge の作成は、manage_ovs コマンドを使用します。
  • 基本的に CVM から操作します。(AHV へのコマンド実行も CVM から)
  • CE のバージョンは ce-2018.01.31-stable です。

今回は、ESXi で起動している Nested Nutanix CE です。これは、下記のようにセットアップしています。

Nutanix CE は、4 ノードのクラスタ構成にしています。Nutanix Cmdlets でクラスタに参加しているノードを見ておきます。

NTNX> Get-NTNXHost | select @{N="Cluster";E={(Get-NTNXCluster -Id $_.ClusterUuid).name}},name,hypervisorAddress,serviceVMExternalIP,hypervisorFullName | sort hypervisorAddress | ft -AutoSize

Cluster     name            hypervisorAddress serviceVMExternalIP hypervisorFullName

ESXi 上の VM にしているので、PowerCLI で Nutanix CE をインストールしている VM の構成を見ておきます。

PowerCLI> Get-Folder nutanix-4node | Get-VM | Get-VMGuest | select VM,{$_.IPAddress | where {$_ -like "192*"}} | sort VM

VM       $_.IPAddress | where {$_ -like "192*"}
--       --------------------------------------
ntnx-n11 {192.168.1.181, 192.168.5.1}
ntnx-n12 {192.168.1.182, 192.168.5.1}
ntnx-n13 {192.168.1.183, 192.168.5.1}
ntnx-n14 {192.168.1.184, 192.168.5.1}

それぞれの ESXi の VM に、vNIC(Nutainx AHV から見ると物理 NIC)が 4つあります。

PowerCLI> Get-Folder nutanix-4node | Get-VM | Get-NetworkAdapter | select Parent,Name,MacAddress | sort Parent,Name,PortGroupName

1台だけ、Open vSwitch の全容を見ておきます。Nutanix CE は ce-2018.01.31-stable から突然 Open vSwitch の様子が激変しました。多分マイクロセグメンテーション(microseg とかもあり)関連の影響かなと思います。
