我正在尝试安装 KVM。我已经完成安装,现在正在执行指导使桥接网络正常工作。但是,我被困在需要修改文件的部分/etc/network/interfaces
。
(注意:我没有安装 X。)
我在Ubuntu Server 15.04上:

该文件当前如下所示:
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto p17p1
iface p17p1 inet dhcp
#auto virbr0
#iface virbr0 inet dhcp
# bridge_ports p17p1
# bridge_stp off
# bridge_fd 0
# bridge_maxwait 0
如果我取消注释最后几行,并且systemctl restart networking
网络连接p17p1
丢失,ifconfig
则显示p17p1
和virbr0
都有相同的 IP 地址。
我应该使用静态设置吗?
答案1
您不需要使用静态设置。
另外,我看到您已经找到了这个答案
对于动态 IP 地址解决方案,您应该设置一个真正的网桥并使用它。您的接口文件应该变成:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
auto br0
iface br0 inet dhcp
bridge_ports p17p1
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off
