Hello everyone, I installed for the first time Ubuntu 13.04 (64X UNITY) on my computer, and deleted my old windows. I Was sure I was going to improve my computer performance, but I found that Ubuntu is running very slow. Every simple task takes a lot of time and the loading time takes forever. It's funny because my system now have a slower response time comperes to the response time of my old windows. the hardware is old, but relatively fine: Processor: Intel ® Core ™ 2 Duo CPU...

Using VirtualBox you can create and run guest operating systems (“virtual machines”) such as Linux and Windows under a host operating system. There are two ways of installing VirtualBox: from pre-compiled binaries and from the sources code. This tutorial shows you how to set up VirtualBox 4.3 from the pre-compiled binaries.

From the version 2.0 VirtualBox supports 32 and 64bit host and guest operating systems (if you want to install 64bit guests your processor must support hardware virtualization and, of course, the host operating system must be 64bit as well).

Step 1: Open up the Terminal (Dash Home > Search > Terminal).

Step 2: Open /etc/apt/sources.list file.

sudo gedit /etc/apt/sources.list

Step 4: Add the following line in to that file.

deb http://download.virtualbox.org/virtualbox/debian trusty contrib

Step 3: Import the Public key of the Oracle VirtualBox repository to your system.

wget -q...

Oracle VirtualBox is a cross-platform virtualization application. It installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. VirtualBox can create and run a "guest" operating system (virtual machine) in a window of the host operating system. The virtual machine provides a self-contained environment in which to experiment with new software without risking damaging changes to the host operating system.

We will give an instruction with step-by-step screenshots to show how to install VirtualBox with an example of installing Ubuntu OS as a guest machine. We also explain how to share files between the host and guest operating systems.


Note the instruction here is based on the latest version of the VirtualBox. If you have already installed an earlier version of VirtualBox, your experience may be different. It...

mpack wrote:Allocating 75% of the hosts available RAM to a guest may result in host thrashing.

I allocated 2048 out of 3717 which is 55%. Moreover the host is doing no swapping, without virtualbox running (500MB used), or with virtualbox running (2700MB used).

mpack wrote:While you do have a GAs ISO mounted in the VM, I'm not at all convinced that you've actually installed them. There is no autorun in Win7, so you need to navigate to the guest CD and manually run the VBoxWindowsAdditions.exe installer.

According to Windows' Control Panel it is installed. Also, since I have a decent window resolution I am quite sure GAs are installed and working.

Ubuntu or other Linux distributions may be slow when you run it within VirtualBox. Often, the cause is that not enough RAM is assigned to the virtual machine, which makes it run slow and makes it unresponsive. However, if your VM already has plenty of RAM and you also already tried assigning an extra virtual CPU core to the machine, this guide might help you make Ubuntu faster in Oracle VM VirtualBox.

Execute the following command to see if 3D acceleration is being used or not:

/usr/lib/nux/unity_support_test -p

It will probably say:

Unity 3D supported: no

Now that’s bad news, because the graphical interface of Ubuntu makes your whole system slow and laggy. So first of all, make sure you have the VirtualBox Guest additions installed.
Once this is installed, we now install the vboxvideo driver:

sudo bash -c 'echo vboxvideo >> /etc/modules'

Now, shutdown Ubuntu. Then, you open the settings of your virtual Ubuntu and you go to ‘Display‘. Now tick...

Here is a guide to install VirtualBox and the VirtualBox extension pack. I will also show you how to add your username to the vboxusers group to enable the USB support.

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2. See “About VirtualBox” for an introduction.

I downloaded and installed VirtualBox 4.3.26 for Windows hosts and Ubuntu 14.04.1 64-bit, and my host operating system is Windows 8.1 Pro 64-bit. When I try to create a new virtual machine, I only have the option of installation-> Ubuntu (32bit) system.

I found a lot of similar articles with my problem and people say that I must go to bios and change Virtualization option to enabled. The thing is that I don't have such an option in my bios.

I found on this page, the following information: "our PC processor and motherboard should support this feature, if they don’t, you can’t do anything to get this feature because it’s a built-in hardware feature. "

My processor is Pentium(R) Dual-Core CPU T4500. Is there any option to install Ubuntu 14.04.1 64-bit on my Oracle VBM?

When I installed Ubuntu 14.04.1 32-bit on VBM it worked veeeerrrrryyyyy slowly (I gave 1GB RAM for Ubuntu). I thought that if I find an answer how to install Ubuntu 14.04.1 64-bit, it would...

My Linux VirtualBox guest OS often runs out of space – I never learn that to build anything in Linux, you need about 10 times the amount of space that you think you need. Also, VirtualBox recommends very small default values, so it is easy to be caught out.

Anyway, here are the current steps to re-size a VirtualBox disk, where Linux is the guest OS and Windows is the host OS.

In this example I am using VirtualBox 4.2.6 (The approach is valid with more recent versions also). The host OS (the one that is running VirtualBox) is Windows 7 and the guest OS that I wish to re-size is Ubuntu. Please backup everything before continuing as something could always go wrong.

Step 1. (Optional) Move the VDI file in Windows

If you need to move the VDI file to another location/physical drive with more space, you can do the following.

With VirtualBox shut down, using Windows Explorer move your vdi file (e.g., “c:\MyLinux.vdi“) to its new location (e.g.,...
