主网络接入为万兆,但是虚拟机使用VMXNET3无法识别为万兆网卡

Hi

我的unraid主网络接入为万兆,网卡为Mellanox CX341A ,但是linux的虚拟机使用VMXNET3无法识别为万兆网卡。windows的虚拟机可以识别为万兆网卡。有谁知道问题出在哪里吗?我已经在debian和centos上均测过无法识别为万兆。

 

以下为unraid下查看的eth0网卡的信息。

以下为debian系统下的虚拟BR0网卡使用的VMXNET3:

更换虚拟网卡类型试试:virtio/virtio-net/e1000

设置Network Source为Br0,Network Model设置成virtio/virtio-net/e1000/Vmxnet3都无法识别成万兆。已经在centos7.9/debian11虚拟机和安装盘安装时候识别的网络类型也尝试过了,均无法识别成万兆,最高只有千兆。问题会出在哪里呢?
