linux 上的 Virtualbox 重置了 vboxnet0 的 IP 地址

Question

当尝试通过 java 后端连接到 virtualbox-guest-machine 中的服务时，我注意到 vboxnet0 接口的 IP 地址变为重置（bug reported but closed 2012).

virtualbox 中的访客机是：

WinXP（IP：10.0.2.15，子网掩码：255.255.255.0）

主机系统运行虚拟机是：

Ubuntu, vboxnet0 (IP: 192.168.56.1, 子网掩码: 255.255.255.0)

这些是我用来强制将 vboxnet0 接口设置为 ip 10.0.2.2 的命令：

[root@rm-2  rm2.sxixus.de ~]# ifconfig vboxnet0 && date
vboxnet0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.56.1  netmask 255.255.255.0  broadcast 192.168.56.255               <-- WRONG at 12:04:26

由于我在服务器上有大约 20 台不同的来宾机器和 400 个不同的快照，因此 vboxnet0 接口的 IP 地址不应更改。

问题

~~如何修改inet接口的ip地址vboxnet0?~~

如何避免virtualbox IP地址被更改？

Answer 1

好的，我在这个网络接口上创建了第二个 ip 地址，一切顺利。

linux 上的 Virtualbox 重置了 vboxnet0 的 IP 地址

Virtualbox reset IP-address of vboxnet0 on linux

java

testing
