在 KVM 上安装

本节介绍了如何使用 libvirt 运行 SD-WAN Orchestrator。该部署已在 Ubuntu 18.04 LTS 中进行测试。

映像

对于 KVM 部署，VMware 将在 4 个 qcow 映像中提供 SD-WAN Orchestrator。

• ROOTFS
• STORE
• STORE2
• STORE3

这些映像会在部署时进行精简置备。

首先，将这些映像复制到 KVM 服务器。此外，您还必须按照上一节中所述复制 cloud-init ISO 内部版本。

XML 示例

注： 对于 images/vco 文件夹中的映像，您将需要从 XML 进行编辑。

创建虚拟机

要使用标准 virsh 命令创建虚拟机，请运行以下命令：

virsh define vco.xml
virsh start vco.xml
