If you want to use VirtualBox shared files, the desktop resolution magnification feature, you must install the VirtualBox enhancement Pack.
I install VirtualBox under Ubuntu, the process:
[Email protected]:~$ uname-alinux huwei 3.19.0-31-generic #36 ~14.04.1-ubuntu SMP Thu Oct 8 10:21:08 UTC x86_64 x86_6 4 x86_64 gnu/linux[email protected]:~$ vim/etc/apt/sources.list
Add the following content
Deb Http://download.virtualbox.org/virtualbox/debian Vivid Contrib
Then import the key
Wget-q https://www.virtualbox.org/download/oracle_vbox.asc-o-| sudo apt-key add-
Install after update
sudo apt-get updatesudo apt-get install virtualbox-4.3
To this installation VirtualBox successful, 5.0 after the installation of some unresolved issues, so I would still be conservative, install a lower version.
Installs the enhanced mode. First confirm your VirtualBox version. Open VirtualBox, press f1,help the first line of the document displays the version number:
