google出来的解决方案：创建静态ip的方法，既然虚拟机桥接模式下无法通过主机网卡获取ip桥接到网络，那么我们就创建最大网络地址，然后reboot，这样虚拟机就可以获取ip联网了。
Static IP address assignment:
Choose one of the following methods:
- Command Line:
/sbin/ifconfig eth0 192.168.10.12 netmask 255.255.255.0 broadcast 192.168.10.255
Network address by convention would be the lowest: 192.168.10.0
Broadcast address by convention would be the highest: 192.168.10.255
The gateway can be anything, but following convention: 192.168.10.1Note: the highest and lowest addresses are based on the netmask. The previous example is based on a netmask of 255.255.255.0
- Red Hat / Fedora GUI tools:
-
/usr/bin/neat Gnome GUI network administration tool. Handles all interfaces. Configure for Static IP or DHCP client.
(First available with Red Hat 7.2.) - /usr/bin/netcfg (Handles all interfaces) (last available in Red Hat 7.1)
-
/usr/bin/neat Gnome GUI network administration tool. Handles all interfaces. Configure for Static IP or DHCP client.
- Red Hat / Fedora Console tools:
- /usr/sbin/system-config-network-tui (Text User Interface)
- /usr/sbin/netconfig (Only seems to work for the first network interface eth0 but not eth1,...)
- Directly edit configuration files/scripts. See format below.
