👊🏾 🏻 🙋🏾 带有虚拟化的Open vSwitch集成 👖 👩‍🌾 👆🏾

必须以某种方式将Open vSwitch（OVS）与R虚拟化加R存储（RP）集成在一起，这不仅有用，而且还有用。

在撰写本文时，RP的当前版本为7.0.13-31，此版本中的核心为3.10.0-1062.12.1.rv7.131.10.1，与RedHat版本7.7相对应，RP存储库随附的OVS版本为2.0。 0。可以在此处找到OVS 2.0.0的功能列表。RP的密钥可以在这里找到。

目标是尝试配置VXLAN和虚拟交换机，以替代本机kvm-qemu和libvirt桥。如果您使用裸露的OpenSource kvm-qemu，那么使用OVS一切都很好，但是我想在RP上尝试，其中不仅是裸露的kvm-qemu + libvirt，而且这个捆绑包的许多补丁都是vstorage。
