Three simple settings that make Ubuntu in virtualbox better

Ubuntu 9.04 is installed in virtualbox 3.0.4 because of work needs (the hard drive is too late, and the performance of the current machine running the virtual machine is also good ). However, after the installation, it is uncomfortable to use it without some proper configuration.
1) Resolution Solution
In the default configuration, the resolution of ubuntu as the client (guest) can be adjusted to a maximum of 800 × 600. The screen size in virtualbox is not adjustable, And it looks uncomfortable.
The solution is simple: Install the virtualbox Toolkit:
Device (on the menu bar of the virtualbox client running window)-> install the enhancement feature (a virtual optical drive icon is displayed on the desktop after you click it), and then click Run to install it as prompted.

2) modify the hotkey
By default, the hot key for switching between virtualbox and Windows is the right ctrl key. This default setting is equivalent to self-harm for people who use Emacs. How can this work? You can reset the hotkey. On the main interface of virutalbox, choose manage> global Settings> hotkey.
3) share files with Windows
Since virtual machines are used, we often need to exchange files and data between two systems. When windws is the host machine and Ubuntu is the guest machine, we can easily implement data exchange between windows and Ubuntu by sharing files.
On the Control Panel of the virtual machine, choose "device-> allocate data space" to allocate a "fixed allocation" Data Space (remember your name ), this data space is our shared folder.
Then we can create a ing point in Ubuntu, that is, a brand new Folder:
# Sudo mkdir/Media/Windows-share

Windows-share can be replaced by any name you like.
Then, we can mount the shared folder in windows to the folder we created earlier:
# Sudo Mount-T vboxsf folder-name/Media/Windows-share

This folder-name must be replaced by the name of the shared folder you created earlier.
Using the three simple configurations above, UBUNTU in virtualbox is much more comfortable to use.
In addition, by the way, virtualbox's current "seamless connection" mode is amazing!
