It runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems such as Windows, Linux and OpenBSD. In a previous guide I have shown you How to install Ubuntu Linux on Windows using VirtualBox .
The procedure is the same if you want to install Windows on Linux. The guest operating system is installed on a virtual disk created by VirtualBox which is nothing more than a single .vdi file. When you first create the virtual machine you must set a certain size for this disk. However after playing with VirtualBox you might realize you need more space because your virtual disk is full So, in this tutorial I will explain how to enlarge an existing virtual disk or in other words how to resize your virtualbox vdi. **Note: The same procedure works for Windows Vista also. Run VirtualBox and go to File -> Disk Manager. Press Finish to end the wizard. Tutorial: All about VDIs (View topic) • virtualbox.org.
Q: How can I reduce the size of a dynamic VDI on disk? A: There are two approaches to cleaning up and reducing the size of the file system stored on a dynamic VDI. The first is what I call in-place and the second is by doing a file system copy. This answer addresses the first of these. You must prepare the file system before you attempt to reduce its size, otherwise the benefit will be minimal. You then need to use a utility to zero the free space within the file system (remember that in general free space will not be zero, because it will contain data blocks that have been used and recycled to the file system). The best tool to use for NTFS under a Windows guest OS is the System Internals (now part of Microsoft) tool sdelete (Microsoft SysInternals File Utillities). Code: Select all Expand viewCollapse view sdelete -c Csdelete -c D In the case of Linux, a good utility for ext2, ext3 and ext4 file systems is zerofree written by Ron Yorston and available on his website:zerofree.
Resize An Existing .vdi Virtualbox Image – EASILY! By Gregory Milby. How to expand (grow) a VirtualBox VDI file | mdl4. The process of duplicating or compacting a VDI file is relatively straightforward (see older posts for details), once you figure out the tricks. While duplicating and compacting functionality is built in to VirtualBox, unfortunately, increasing the size of a VDI disk is a little more difficult. Synopsis 0. Back up your original VDI and all data! 1. Create an empty vdi file with the space you need. 2. Make your new, empty vdi the primary slave of the virtual machine attached to the drive you wish to expand (which should be the primary master). 3. How to expand a VDI disk file After backing everything up, begin by creating a new, empty VDI file with the space you need. VirtualBox's Virtual Media Manager GUI Once the new disk has been created, attach it to a virtual machine along with the VDI you wish to expand.
Attach your new VDI to the machine's storage tree If the VDI you wish to expand has the root filesystem or operating system on it, make sure it’s the primary master. More information. How To Shrink Your Virtualbox VM And Free Up Space For Your Hard Disk. Howto increase hard disk size after installing a guest OS (View topic) • virtualbox.org. Just to confirm that GusGan's approach works just fine for XP, at least. I managed to clone a physical machine to VirtualBox with the help of TrueImage, but found 10GB was far more than I really needed once I had cleared out a load of unneeded applications.
So after closing down, I unhooked the 10GB image from its VM and attached it as a first slave to an XP VM on which TrueImage is installed, and then created and attached a 6GB vdi as a second slave. I then used TrueImage to clone the contents of the 1st slave "down" to the 2nd slave. "Powered down", unhooked the 6GB from the XP VM and attached it to the previously 10GB VM. I would think the same technique ought to work for a Linux vdi. Oddly, TrueImage wouldn't "restore" directly from a .tib image on a USB drive attached to a VM. A word of warning - cloning from a physical machine is not necessarily straightforward: I had to remove some drivers (AGP and processor), and do a repair install.
Copy and Clone Virtual Machines in VirtualBox with CloneVDI Tool. Unfortunately Oracle VirtualBox is missing virtual machine cloning tool. If you need to copy or clone a virtual machine without re installing OS and other applications, then you are in trouble with VB. This post explains how to copy and clone virtual machines in VirtualBox with CloneVDI GUI tool, a third party software. VMware has great built in cloning tool, allows to make two types of cloning very quickly. Read more about it here. Earlier I have published a similar post that cab be done in command prompt. It works well with ‘VBoxmanage’ command. I recommend to read the post before continue reading. The CloneVDI tool does the same command execution but in Graphical user Interface (GUI). Download Latest CloneVDI Tool 2.02 here. 1) Extract the downloaded zip file. 2) Before start the process, let me explain how it is going to work. This tool clone the hard disk file only. This tool does not clone VM configuration XML file. 2 – is the disk file currently virtual machine is running.

File system can become inconsistent due to several reasons and the most common is abnormal shutdown due to hardware failure , power failure or switching off the system without proper shutdown. Due to these reasons the superblock in a file system is not updated and has mismatched information relating to system data blocks, free blocks and inodes . fsck – Modes of operation : fsck operates in two modes interactive and non interactive : Interactive – fsck examines the file system and stops at each error it finds in the file system and gives the problem description and ask for user response whether to correct the problem or continue without making any change to the file system.
If file system is found to have problem at the booting time non interactive fsck is run and all errors which are considered safe to correct are corrected.

Thanks for visiting! Sponsored Link We have already discussed how to install virtualbox and create virtual machines in ubuntu.This tutorial will explain How to set up host interface networking for VirtualBox on Ubuntu. To start, NAT is by far the easiest way to get your guests connected to the interweb, but you may want to use the guests as servers. To configure Host Networking you need to configure network bridging, you basically go through four steps on the host machine Install necessary packagesDeclare bridge and real network interface you add to itDeclare virtual interfacesSet permissions on /dev/net/tun Preparing Your system You need to install the following packages sudo apt-get install uml-utilities bridge-utils Now you need to take the backup of your networking file using the following command sudo gedit /etc/network/interfaces That's it!
