VirtualBox启动运行错误

问题

virtualbox 启动虚拟机时提示：

The virtual machine 'fedora' has terminated unexpectedly during startup with exit code -1073741819 (0xc0000005)

解决方案

这是因为跟系统上某些程序（MacType Tray）冲突导致的，

VirtualBox 4.14 has new "hardened" security on Windows, 
and it doesn't play nice with anything that hooks dll's into Windows, 
mainly 3rd-party antivirus packages, but also any other 3rd-party program 
that "intercepts" Windows dll calls.

如果VBox被DLL注入（MacType，各种杀毒软件），那就会启动失败

此时，只需要在启动VirtualBox的情况下，管理员权限打开MacType用户向导，然后将对应的virtualbox程序停用即可，此时，virtualbox 虚拟机即可启动。
