CentOS Virtualbox无法访问互联网

CentOS Virtualbox无法访问互联网

我有以下问题:

我有一台安装了 CentOS 的虚拟机。我无法从这台机器连接到互联网,因此无法升级其上安装的任何内容。

VM 配置为:

在设置 -> 网络下

  • 适配器 1
    • NAT
  • 适配器 2
    • 主机专用适配器
    • 名称:vboxnet0
    • 混杂模式:拒绝
    • Calbe Connected:是的

在“文件”->“首选项”->“网络”下的“仅主机网络”中,vbonenet0

  • IPv4 地址:192.168.101.1
  • Ipv4 网络掩码:255.255.255.0
  • IPv6 地址:fe80:0000:0000:0000:0800:27ff:fe00:0000
  • IPv6 前缀长度:64

当我在机器上时:

有人能帮助我吗?谢谢你的支持。

更新

默认网关是:

ip r | grep default
default via 192.168.101.2 dev eth1 

答案1

确保 VirtualBox 网络适配器的 MAC 地址等于文件 ifcfg-eh0 和 ifcfg-eh1 中声明的硬件地址 (HWADDR)。直到我修复了这个问题,我的网络才能够正常工作。
