在Win7為HOST的環境下，安裝VirtualBox，在其中安裝CentOS7，以Bridge的方式搭建網絡環境。

主要配置包括VirtualBox中的網絡設置，以及CentOS中的網絡配置。另外還有個重要的注意點就是如果HOST使用的是無線網，那麼即使bridge配置成功了，虛擬機能夠與主機互相ping通，虛擬機也無法訪問外網。

 

VirtualBox網絡配置

baremetal hypervisor場景下host vm與client vm的角色_IPV6

 

CentOS網絡配置

修改網絡配置文件：

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

修改後內容：

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=6ce977fe-843a-4fb3-8bda-40b7ae4fc4f5
DEVICE=enp0s3
ONBOOT=yes
HWADDR=08:00:27:7a:0d:c3
IPADDR=192.168.0.150
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=192.168.0.1

 

 

安裝VirtualBox Guest Additational

安裝依賴：

yum install kernel-headers
yum install kernel-devel
yum install gcc* 
yum install make

安裝完成之後重啓一下，然後點擊虛擬機窗口上的安裝增強（如果guest中已經加在過了鏡像，就將其退出），然後稍等一會就安裝完成了。

如果報以下錯誤：

this system is currently not set up to build kernel modules

則有可能是kernel的幾個包的版本不一致，使用命令：

rpm -qa kernel* |sort -V |tail -n 5

查看幾個包的版本是否一致：

kernel-3.10.0-693.el7.x86_64
kernel-devel-3.10.0-693.5.2.el7.x86_64
kernel-headers-3.10.0-693.5.2.el7.x86_64
kernel-tools-3.10.0-693.el7.x86_64
kernel-tools-libs-3.10.0-693.el7.x86_64

如果不一致，可以使用以下命令進行更新：

yum -y upgrade kernel kernel-devel kernel-devel

更新完重啓後，再次安裝增強控件。

 

CentOS分辨率問題（存在問題）

以下過程是參照網絡上的資料執行的，不過在執行過程中報了一個錯，可能是缺少驅動的問題，此處我沒有再進一步解決，就此打住了，因為是打算設置一個Linux的Java開發環境，因此打算換一個比較容易操作的版本，換成Ubuntu了。

下面的操作直接導致系統卡在啓動界面了，解決方法可以參考日誌：

執行命令：

Xorg :1 -configure
