我可以从我的PC上ping到AHV。我可以通过AHV通过地址172.x.x.x和内部地址192.x.x.x ping到CVM，但是我可以从PC上ping到CVM。

I can ping to AHV from my pc. I can ping to CVM from AHV via address 172.x.x.x\u00a0 and internal address 192.x.x.x But I Can Ping To CVM From My PC.<\/p>","quoteUsername":"Bilel","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @BiLel

请确认从哪里到您无法ping的地方，在所有三种情况下，您都提到您可以ping。请检查您的VLAN配置，并确保CVM配置了正确的子网和网关。

Hello\u00a0@Bilel<\/user-mention>\u00a0

Please confirm from where to where you can\u2019t ping, in all 3 scenario you have mentioned you can ping.\u00a0 Please check your vlan configuration, and make sure CVM have the correct subnet and gateway configured.\u00a0<\/p>","quoteUsername":"Sudhir9","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @BiLel

从AHV分享以下命令的输出

cat/etc/sysconfig/network-scripts/ifcfg-br0 ovs-vsctl显示virsh dumpxml ntnx* |GREP标签

从CVM中，请分享以下命令的输出

cat/etc/sysconfig/network-scripts/ifcfg-eth0
