安装vitualbox并配置共享目录

```123```

```php

echo 123;

```

安装vitualbox软件:

https://download.virtualbox.org/virtualbox/5.2.44/VirtualBox-5.2.44-139111-Win.exe

配置vitualbox

下载centos7.iso镜像, 点击新建, 安装虚拟机系统

设置网络模式为桥接模式

进入终端界面, 修改网卡配置, onboot改为yes并设置为静态网卡(static)

设置resolv.conf, 网关为外层主机所用的网关

重启网络, 使用xshell连接上虚拟机, 测试网络状态

我的静态网卡配置参考:

```bash

# 路径 /etc/sysconfig/network-scripts/ifcfg-enp0s3

# 文件内容

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=ac6920ed-68fc-4e76-b212-cb8a1c1f59b3

DEVICE=enp0s3

IPADDR=192.168.1.102

GATEWAY=192.168.1.1

NETMASK=255.255.255.0

无法卸载virtualBox, 提示"无法访问您试图使用的功能所在的网络位置的解决办法"

方法1. 找到提示所指的.msi文件

方法2: 找到virtualbox.exe, dos命令执行 virtualbox.exe --extract, 生成msi回到方法1

方法3: 重新下载当前版本的安装包, 安装软件并选择修复功能; 重启电脑后就可以卸载了

记得检查注册表是否有遗留的项, 手动删除

获取virtualbox com对象失败(Failed to Acquire the VirtualBox COM Object)

参考以下文章: https://appuals.com/how-to-fix-the-failed-to-acquire-the-virtualbox-com-object-error/ , 卸载并用管理员身份安装, 得到新的配置文件

C:\Users\Administrator\.VirtualBox\VirtualBox.xml

检查文件, 大小为4k;

重启VB, 报错在C:\Users\hasee.VirtualBox\VirtualBox.xml第一行, 检查该文件大小0k;

复制C:\Users\Administrator.VirtualBox\VirtualBox.xml覆盖C:\Users\hasee.VirtualBox\VirtualBox.xml, 重启VB

正常运行!

开机提示"Broken shared folder!"

修改了/etc/fstab文件就会报错, 把改动的内容全部改回来; 包括空格

Host system reported disk full. VM execution is suspended. You can resume after freeing some space.

查看centos7.vdi文件所在的磁盘, 发现磁盘空间不足, 配置30G的虚拟系统只用了2G

迁移vdi文件到另一个磁盘

https://www.cnblogs.com/xwdreamer/p/3363451.html

UUID {5503e069-85ff-4c81-bac0-86bbe2896f0b} of the medium 'F:\Virtual Machines\centos7\centos7.vdi' does not match the value {83c4db83-0b2d-4308-a742-c8e785cff46a} stored in the media registry ('C:\Users\hasee.VirtualBox\VirtualBox.xml').

找到cenros7.vdi, 修改文件名; 在虚拟机存储设置重新添加虚拟磁盘
