If you are unsure about the name of your virtual machine, the following command will list all your virtual machines by name: VBoxManage.exe list vms In the command prompt, go to your VirtualBox installation folder and type the following ( Figure H): VBoxManage.exe modifyvm -nested-hw-virt onįigure H Activate the Nested VT-x/AMD-V parameter in the command line. Quit VirtualBox, and launch a command line by hitting the Windows key of your keyboard and type cmd.exe, then hit the Return key. It is called Enable Nested VT-x/AMD-V in the system/processor tab of VirtualBox, but is grayed out and cannot be activated with the GUI. Select the ISO file, click Open, then click OK.Ĭonfiguration is now OK in VirtualBox, except for one parameter we need to activate via the command line of our Windows system. Choose Disk File ( Figure G).įigure G Choose the ISO file for installation. Go to the Storage tab, click the CD ROM image that says Empty in the middle pane, and click on the second CD ROM image on the right pane. In the System tab tick Enable EFI (special OSes only) ( Figure F). Right-click on the new virtual machine, and select Settings ( Figure E).įigure E Access the settings for the virtual machine.Ĭhange all the settings according to your needs and hardware. The virtual machine environment is now ready. The next step is setting the size of the virtual hard drive ( Figure D).įigure D Set the virtual hard drive size.Ĭlick Create, and wait for the VirtualBox to finish setting up. SEE: Linux turns 30: Celebrating the open source operating system (free PDF) (TechRepublic) Eighty gigabytes is generally a good size for this kind of virtual machine, but of course it all depends on your hardware and the space left on it. The dynamically allocated option will only consume disk storage as it fills up. The fixed size option allows you to set a maximum size that will never change on the physical hard drive. It’s now up to you to choose between a dynamically allocated virtual hard drive or a fixed-size one. Select VDI as the hard disk file type, then click Next. Change the folder according to your needs, and select Linux / Fedora (64-bit) ( Figure B).įigure B Creating the new virtual machine in VirtualBox.Ĭlick Next then select the size of the memory (RAM) you wish to be allocated to the virtual machine ( Figure C).įigure C Setting RAM capacity for the virtual machine.Ĭlick Next, select Create a Virtual Hard Disk Now, then click Create. For our installation, we will call it QubesOS-vm. Open VirtualBox and choose Machine/New then choose a name for the virtual machine. We also need to download the Qubes OS ISO file–stable release ( Figure A).įigure A The download options from the Qubes OS website.Ĭhoose your favorite way of downloading (direct download or via torrent), check the file hash when done, and you’re ready to install. Here is a guide to install Qubes OS in VirtualBox, the host being a Windows operating system. Users without experience with Qubes OS should first go for a virtual machine installation to get the feel and really test it before installing. It is recommended to have 16GB of RAM and 128GB of SSD free space. It also needs 64-bit Intel or AMD processor, 6GB of RAM and 32GB of hard disk free space. Qubes OS has very specific hardware requirements, in particular the need for IOMMU-based virtualization in the BIOS or UEFI. To get the best of Qubes OS, it is, of course, better to make a full installation of it on a computer. Qubes OS also allows the user to simultaneously run multiple operating systems: Windows, Debian and Fedora. This way, if the user visits fraudulent websites spreading malware, he or she is still safe.

To make it simple to understand, every qube is implemented as a virtual machine that is fully configurable by having specific purpose, nature and level of trust. It leverages Xen-based virtualization, which allows the user to create, use and delete easily isolated compartments called qubes. Qubes OS is a free open-source operating system that’s fully security-oriented.
