VirtualBox is a software which allows the user to run variety of operating systems be it Windows, Mac or BSD or any other OS. Fortunately, VirtualBox is available for Ubuntu 16.04 and the installation is a fairly easy process. After you’ve installed the VirtualBox you will need the bootable ISO to configure the Virtual OS to run through Virtual Box.

In order to install VirtualBox follow the steps below.

Installing VirtualBox on Ubuntu 16.o4

Click the search your computer icon from the top left and type Terminal. Click Terminal to open it.

Download the deb file using the wget command from here. I recommend using the AMD64 bit version regardless of the CPU type you have because it contains the same set of instructions.

In terminal, type or copy/paste the following command

wget http://download.virtualbox.org/virtualbox/5.1.10/virtualbox-5.1_5.1.10-112026~Ubuntu~xenial_amd64.deb

PRO TIP: If the issue is with your computer or a laptop/notebook...

If you’re getting an error that “Windows failed to start” while trying to install 64bit Windows 7 on a Virtualbox machine with an Ubuntu host, then you’ll appreciate the following fix.

Go ahead and open Virtualbox. Right-click the virtual machine that you intend use for the Windows 7 installation. Then click “settings”.

In the settings box that appears, click “System”.

Now, check the box that reads “Enable IO APIC” and then click “OK”. At this point, you should be able to boot up the virtual machine without seeing the error message.

However, you may get a new error… that windows cannot install to your disk. In that case, you’ll need to change the type of controller your virtual machine uses for the virtual disk.

So, select “Storage” from the options on the left and, if you see that your virtual disk is attached to an SATA controller, remove it.

Now select the IDE controller and attach the...

Yesterday, after trying out

TestDrive

in Ubuntu, which installs QEMU, I got this error when trying to open a virtual machine in VirtualBox:

VirtualBox can't operate in VMX root mode

Luckily, there is an easy fix for Linux users. All you have to do is run the following command with root privileges (the command has also been added to the Ubuntu TestDrive post, of course):

For Ubuntu, just use "sudo" in front of the command. Unfortunately I don't know a fix for Windows users other than just using a single virtualization application (so no more than one!).

Hopefully this will help some people. Using it, you can run both Ubuntu TestDrive (which uses QEMU) and VirtualBox without any...

I'm doing a tutorial through lydna.com on setting up linux using virtualbox.

It was going fine until I had to create a file in my development folder. It's been set up as a shared folder so I can write html files straight on to the virtual server (I think).

I'm writing small scripts in to the shared folder and I'm getting a 404 error for each. For something like http://sandbox.dev:8080/errors.php or http://sandbox.dev:8080/hello.html (with just a 'hello world' in there).

Additional Info;

In VirtualBox if I go settings->shared folders->machine folders, my 'sandbox' folder is definitely the one being used.

When I go to http://sandbox.dev:8080/server-status - it works as expected. Information about the server.

I have installed Ubuntu 14.04 LTS. I've installed a lot of packages. Things started going wrong on the 'Configuring the Apache web server' section so maybe it's an apache problem.

I have looked on the server through the command...
