请问下各位大佬,在宿主机上ping www.baidu.com不丢包,但是使用宿主机上的虚拟机内部ping www.baidu.com丢包很严重,如何查问题?

先看下虚拟机 ping 网关有没有丢包,然后看 dns 解析出来的地址和宿主机是不是一样的

虚拟机 ping 网关确实丢包严重,宿主机ping网关不丢包。

是VPC内的虚机

vpc
起:192.168.0.2
止:192.168.255.253

@yulongz 这个大概率是ovn的chassis和端口配置有不一致的情况,需要用ovn-sbctl查看找到冲突端口和chassis

我们发现了是挂载一个EIP之后才有这种情况,卸载EIP之后就不丢包。机房提供的EIP貌似有问题,此EIP已经从cloudpods里删除。
