尝试在 KVM 上的来宾 VM 之间使用 veth 对。

已经在 linux 上创建了 Veth pair，并且能够在一个上注入流量并在另一个上接收。

在 KVM 中使用 VM 进行测试需要您的建议。找出添加 virsh 转储 xml 的方法。

尝试更新xml

virsh dumpxml NEv1_cc1 > NEv1_cc1_aftstartdumpxml.txt

NEv1_cc1_aftstartdumpxml.txt

... 
<interface type='direct'>
      <mac address='52:54:00:a1:1c:40'/>
      <source bridge='138_craft'/>
      <target dev='v1'/>
      <model type='e1000'/>
      <alias name='net8'/>
      <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x7'/>
    </interface>
...

得到错误：

santoshk@kvmserver:~$ virsh define  NEv1_cc1_aftstartdumpxml.txt
error: Failed to define domain from NEv1_cc1_aftstartdumpxml.txt
error: internal error: No <source> 'dev' attribute specified with <interface type='direct'/>

我试图遵循以下水龙头/桥的类似线路


   <interface type='bridge'>
      <mac address='52:54:00:a1:1c:43'/>
      <source bridge='138_craft'/>
      <target dev='tap391'/>
      <model type='e1000'/>
      <alias name='net7'/>
      <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x7'/>
    </interface>

主机上的 veth 对：
