桥接模式下配置虚拟机连接互联网

需要保证桥接的网卡可以正常上网
ip和物理机的网卡处于同一网段
配置网关和DNS
ping物理机、ping网关

nmcli相关命令

[root@alexw-device ~]# nmcli connection --help
Usage: nmcli connection { COMMAND | help }

COMMAND := { show | up | down | add | modify | clone | edit | delete | monitor | reload | load | import | export }

  show [--active] [--order <order spec>]
  show [--active] [id | uuid | path | apath] <ID> ...

  up [[id | uuid | path] <ID>] [ifname <ifname>] [ap <BSSID>] [passwd-file <file with passwords>]

  down [id | uuid | path | apath] <ID> ...

  add COMMON_OPTIONS TYPE_SPECIFIC_OPTIONS SLAVE_OPTIONS IP_OPTIONS [-- ([+|-]<setting>.<property> <value>)+]

  modify [--temporary] [id | uuid | path] <ID> ([+|-]<setting>.<property> <value>)+

  clone [--temporary] [id | uuid | path ] <ID> <new name>

  edit [id | uuid | path] <ID>
  edit [type <new_con_type>] [con-name <new_con_name>]

  delete [id | uuid | path] <ID>

  monitor [id | uuid | path] <ID> ...

  reload

  load <filename> [ <filename>... ]

  import [--temporary] type <type> file <file to import>

  export [id | uuid | path] <ID> [<output file>]

windows和linux之间的FTP

在保证宿主机和虚拟机之间可以ping通的情况下，使用WinSCP连接
上传软件包
