虚拟机网络一般有三种模式如下,目前主要用的就是Bridge模式,所以这里主要是看看网桥的通讯过程。 Host-Only: 这种模式下,VM只能与Host之间进行网络通讯,与网段内其它的机器处于隔离的状态 Nat: 显然这种模式下,虚拟机要与网段内其它的机器或者外网的机器通讯时,必须要走nat Bridge: 这种模式下,虚拟机相当于网段内一...
1.在创建一个vm并启动时,在host中就会创建一个tap类型的网卡,例如tap0,同时vm作为一个qemu进程,内核为其提供了一个/dev/net/tun设备的文件描述符(fd)14,供其读写。 [root@localhost]$ ps -ef |grep qemu root 12570 1 3 09:52 ? 00:00:24 qemu-system-x86_64 -name one_socket -daemonize -hdb ...
虚拟化(3) qemu虚拟机实现host-only网络 目标: 主机上公网,虚机不能上公网。虚机可以和主机通信。 步骤: (0)第2篇是桥接,本文是在前篇理解的基础上,稍加调整即可。 (1)主机新建网桥,设置ip信息 192.168.10.1 (2)主机把无线网卡连公网。有线网卡不插线,而是接在网桥上。 nmcli connection add type bridge-s...
无论哪种本质上都是在宿主机侧的设置,因为虚拟机的IP网关设置不属于必须操作! 注:建议看完NAT自己实现下host-only模式. host-only 虚拟机是不通外网的(提示,按照NAT的步骤,但不设置防火墙试试) openwrt 虚拟机安装方式 由于openwrt 官方下载的镜像并不是我们以为的 iso 的格式。因此特地记录下 查看镜像文件格式...
