无法将Oracle Linux 6.4虚拟机来宾操作系统连接到网络。无法从主机访问它

我在VirtualBox上的Oracle Linux 6.4上运行了一个Web服务器。它的eth1地址是10.0.2.15。我希望能够从此虚拟机运行Web服务器，但我无法从主机访问虚拟机。客户操作系统也无法上网; 我无法ping谷歌。

目前，虚拟机设置中的网络适配器配置为NAT。这是以下文件/etc/sysconfig/network-scripts/ifcfg-eth1：

DEVICE=eth1
TYPE=Ethernet
#UUID=47fc2dd9-bca4-4912-95b5-7939b3e0ebf5
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=dhcp
HWADDR=08:00:27:06:9c:d5
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth1"
LAST_CONNECT=1392385849

如何在虚拟机设置和来宾操作系统中配置我的网络？

使用ifconfig：

# ifconfig
