Running Linux in a VM
Hardware Requirements
You need a system with virtualization (VT-d), at least 4GB of RAM, and 40GB of free hard drive space in order to run Linux in a VM.
Alternatives
If your system doesn't meet those requirements, you will need to be running Linux, or dual boot your machine so you can run both Linux and Windows. We strongly suggest you use the [http://www.ubuntu.com/download/desktop/thank-you?distro=desktop&bits=64&release=lts Ubuntu 12.04 64-bit version]. If your machine doesn't have 64-bit support, you can use the [http://www.ubuntu.com/download/desktop/thank-you?release=lts&bits=32&distro=desktop&status=zeroc 32-bit version]. Once you have Ubuntu installed, please follow the directions [:OPWfirstpatch:here].
Download Ubuntu 12.04
[http://www.ubuntu.com/download/desktop/thank-you?distro=desktop&bits=64&release=lts Download link to] Ubuntu 12.04 64-bit version.
Install VMPlayer
Go to the [http://www.vmware.com/products/player/ VMPlayer website] and click the 'download' link. Download the VMPlayer that's appropriate for your operating system (e.g. Windows or Linux 64-bit), and install it.
Linux VMPlayer installation instructions
The [http://www.vmware.com/products/player/ VMPlayer download] comes as a .bundle file. That's a binary executable, that will launch a setup wizard.
First, change to the directory where you downloaded the VMPlayer binary by using the command cd.
Tip: cd changes the current working directory to a different directory. You can learn more about any command by reading the manual pages. Simply prefix the command with the word "man", e.g. man cd.
Next, check to see if the file is executable. Run this command:
ls -l
Then look at at the file's listing, and see if it has the executable ("x") bit set:
$ ls -l total 181056 -rw-rw-r-- 1 sarah sarah 185386101 Apr 26 22:19 VMware-Player-5.0.2-1031769.x86_64.bundle
If it doesn't show the executable bit, make the file executable by running:
chmod a+x VMware-Player-5.0.2-1031769.x86_64.bundle
Then execute the binary by prefixing it with a ./ and running it as the root user with sudo:
sudo ./VMware-Player-5.0.2-1031769.x86_64.bundle
- Tip: Be careful about what you run as root! The root user has access to all the files on your system, so you usually don't want to run arbitrary commands as root. Always run commands without sudo, and without changing to a root terminal, where ever possible.
