The manual provides information on how to install Oracle VM VirtualBox and use it to create and configure virtual machines. It is assumed that readers are familiar with Web technologies and have a general understanding of Windows and UNIX platforms. Oracle customers that have purchased support have access to electronic support through My Oracle Support. Oracle is fully committed to diversity and inclusion. Oracle recognizes the influence of ethnic and cultural values and is working to remove language from our products and documentation that might be considered insensitive.
While doing so, we are also mindful of the necessity to maintain compatibility with our customers’ existing technologies and the need to ensure continuity of service as Oracle’s offerings and industry standards evolve. Because of these technical constraints, our effort to remove insensitive terms is an ongoing, long-term process.
Oracle VM VirtualBox is a cross-platform virtualization application. What does that mean? Secondly, it extends the capabilities of your existing computer so that it can run multiple OSes, inside multiple virtual machines, at the same time. As an example, you can run Windows and Linux on your Mac, run Windows Server on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications.
You can install and run as many virtual machines as you like. The only practical limits are disk space and memory. Oracle VM VirtualBox is deceptively simple yet also very powerful. It can run everywhere from small embedded systems or desktop class machines all the way up to datacenter deployments and even Cloud environments. Figure 1. In this User Manual, we will begin simply with a quick introduction to virtualization and how to get your first virtual machine running with the easy-to-use Oracle VM VirtualBox graphical user interface.
Subsequent chapters will go into much more detail covering more powerful tools and features, but fortunately, it is not necessary to read the entire User Manual before you can use Oracle VM VirtualBox. The techniques and features that Oracle VM VirtualBox provides are useful in the following scenarios:. Running multiple operating systems simultaneously. This way, you can run software written for one OS on another, such as Windows software on Linux or a Mac, without having to reboot to use it.
Easier software installations. Software vendors can use virtual machines to ship entire software configurations. For example, installing a complete mail server solution on a real machine can be a tedious task. With Oracle VM VirtualBox, such a complex setup, often called an appliance , can be packed into a virtual machine. Installing and running a mail server becomes as easy as importing such an appliance into Oracle VM VirtualBox.
Testing and disaster recovery. Once installed, a virtual machine and its virtual hard disks can be considered a container that can be arbitrarily frozen, woken up, copied, backed up, and transported between hosts. On top of that, with the use of another Oracle VM VirtualBox feature called snapshots , one can save a particular state of a virtual machine and revert back to that state, if necessary. This way, one can freely experiment with a computing environment.
If something goes wrong, such as problems after installing software or infecting the guest with a virus, you can easily switch back to a previous snapshot and avoid the need of frequent backups and restores. Any number of snapshots can be created, allowing you to travel back and forward in virtual machine time.
You can delete snapshots while a VM is running to reclaim disk space. Infrastructure consolidation. Virtualization can significantly reduce hardware and electricity costs.
Most of the time, computers today only use a fraction of their potential power and run with low average system loads. A lot of hardware resources as well as electricity is thereby wasted.
So, instead of running many such physical computers that are only partially used, one can pack many virtual machines onto a few powerful hosts and balance the loads between them. When dealing with virtualization, and also for understanding the following chapters of this documentation, it helps to acquaint oneself with a bit of crucial terminology, especially the following terms:.
Host operating system host OS. See Section 1. There may be platform-specific differences which we will point out where appropriate. Guest operating system guest OS.
This is the OS that is running inside the virtual machine. But to achieve near-native performance of the guest code on your machine, we had to go through a lot of optimizations that are specific to certain OSes. So while your favorite OS may run as a guest, we officially support and optimize for a select few, which include the most common OSes. See Section 3. Virtual machine VM. In other words, you run your guest OS in a VM.
Normally, a VM is shown as a window on your computer’s desktop. Depending on which of the various frontends of Oracle VM VirtualBox you use, the VM might be shown in full screen mode or remotely on another computer. Some parameters describe hardware settings, such as the amount of memory and number of CPUs assigned.
Other parameters describe the state information, such as whether the VM is running or saved. See Chapter 8, VBoxManage. Guest Additions. This refers to special software packages which are shipped with Oracle VM VirtualBox but designed to be installed inside a VM to improve performance of the guest OS and to add extra features. See Chapter 4, Guest Additions.
Oracle VM VirtualBox runs on a large number of bit host operating systems. Oracle VM VirtualBox is a so-called hosted hypervisor, sometimes referred to as a type 2 hypervisor. Whereas a bare-metal or type 1 hypervisor would run directly on the hardware, Oracle VM VirtualBox requires an existing OS to be installed.
It can thus run alongside existing applications on that host. To a very large degree, Oracle VM VirtualBox is functionally identical on all of the host platforms, and the same file and image formats are used. This enables you to run virtual machines created on one host on another host with a different host OS. For example, you can create a virtual machine on Windows and then run it under Linux. In addition, virtual machines can easily be imported and exported using the Open Virtualization Format OVF , an industry standard created for this purpose.
You can even import OVFs that were created with a different virtualization software. For users of Oracle Cloud Infrastructure the functionality extends to exporting and importing virtual machines to and from the cloud. This simplifies development of applications and deployment to the production environment. Guest Additions: shared folders, seamless windows, 3D virtualization. The Oracle VM VirtualBox Guest Additions are software packages which can be installed inside of supported guest systems to improve their performance and to provide additional integration and communication with the host system.
After installing the Guest Additions, a virtual machine will support automatic adjustment of video resolutions, seamless windows, accelerated 3D graphics and more. In particular, Guest Additions provide for shared folders , which let you access files on the host system from within a guest machine. See Section 4. Great hardware support. Guest multiprocessing SMP. USB device support. Oracle VM VirtualBox implements a virtual USB controller and enables you to connect arbitrary USB devices to your virtual machines without having to install device-specific drivers on the host.
USB support is not limited to certain device categories. Hardware compatibility. Oracle VM VirtualBox virtualizes a vast array of virtual devices, among them many devices that are typically provided by other virtualization platforms. This enables easy cloning of disk images from real machines and importing of third-party virtual machines into Oracle VM VirtualBox. Full ACPI support. This enables easy cloning of disk images from real machines or third-party virtual machines into Oracle VM VirtualBox.
For mobile systems running on battery, the guest can thus enable energy saving and notify the user of the remaining power, for example in full screen modes.
Multiscreen resolutions. Oracle VM VirtualBox virtual machines support screen resolutions many times that of a physical screen, allowing them to be spread over a large number of screens attached to the host system.
Built-in iSCSI support. This unique feature enables you to connect a virtual machine directly to an iSCSI storage server without going through the host system. The VM accesses the iSCSI target directly without the extra overhead that is required for virtualizing hard disks in container files.
See Section 5. PXE Network boot. Multigeneration branched snapshots. Oracle VM VirtualBox can save arbitrary snapshots of the state of the virtual machine. You can go back in time and revert the virtual machine to any such snapshot and start an alternative VM configuration from there, effectively creating a whole snapshot tree.
You can create and delete snapshots while the virtual machine is running. VM groups. Oracle VM VirtualBox provides a groups feature that enables the user to organize and control virtual machines collectively, as well as individually.
In addition to basic groups, it is also possible for any VM to be in more than one group, and for groups to be nested in a hierarchy.
This means you can have groups of groups.
Tech Tip: How to Use Boot Camp on an External Drive.VIP classifieds
Have a suggestion for the blog? Perhaps a topic you’d like us to write about? If so, we’d love to hear from you! Fancy yourself a writer and have a tech tip, handy computer trick, or “how to” to share? Let us know what you’d like to contribute! Installing Windows on an external drive would be a great solution to the problem of available space, but as we said, Boot Camp and Windows impose a restriction on installing to an external drive.
There are actually a few ways you can successfully install Windows on an external drive. It allows you to install Windows on an external drive without first having Windows installed on a PC or in a virtual environment. This is an advanced process with quite a few pitfalls that can trip you up. Be sure to read through the process before undertaking it. Also, make sure you have a current backup before beginning.
Warning : The erase, format, and partitioning process will delete all data currently contained on the external drive. Warning : The process of preparing the USB flash drive will delete any data contained on the flash drive. You can download the app from the VirtualBox website. We will use VirtualBox to install Windows 10 to our external drive.
We can do this because in the previous step, we mapped the external drive to a VirtualBox virtualized disk. In order for VirtualBox to be able to access the external drive, we need to launch VirtualBox with elevated permissions.
Once again, we turn to Terminal. At this point, the Windows installer has copied all the files to the external drive, and has set up a boot environment that you can start your Mac from.
Next time you boot from the external drive, Windows will complete the installation process. The USB flash drive you used earlier to make the Windows Support software contains all the drivers you need to install in Windows for the Apple hardware to work. Once the installation completes, all your Apple hardware, including wireless keyboards and mice, should be working.

Firstly it insists on there being no external storage connected at all not even the USB flash drive and secondly the default action the Assistant offers is to add a Windows partition to the boot drive. Thank you! For anyone having difficulties with these instructions, there are a few errors and necessary clarifications.
Substituting the appropriate disk number as needed. The error is the second set of quotes around bootcamp. If you enter the corrected command this resolves that issue.
You saved my sanity, thank you. May I ask for more tech knowledge? Do you have an idea why that might happen, and how to fix the issue? I have exactly the same issue.
When trying to boot the from the Windows SSD, the disk is not show. I have run into a snag, and am not sure how to resolve it. When I get to the step of selecting the bootcamp. Hello Dakota, I ran into this issue as well. I hope this solves your issue. I would like to partition a hard drive and install windows on one of the partitions. Hello Paulo, I posted a comment on another issue similar, here is what I said and I hope it solves your problem.
Hi, hope someone can help. I have finished all the step successfully in my external drive except installing the bootcamp in Windows. The rest of the process is the same. I need a super mobile and lightweight solution. So I am a little stuck.
When I rebooted my mac, holding option, the only boot option that appeared was my Mac HD. Is it my partition choice that is causing the issue? The EFI? How can I make sure that the computer recognizes the external drive on the option-boot?
Just tried this on Monterey. It does not work. Installation works fine until you need to boot from the USB Stick. I finished to setup on a Big Sur machine and then tried to boot this Windows on my Monterey laptop.
No chance to boot into Windows. Oh thats a shame, if you do ever succeed in finding a workaround, please let me know. Im having to run windows on another laptop, carrying them both around is a real pain. There is nowhere near enough space on my hard drive to partition it for a windows installation. I have just spent many days down a Bootcamp rabbit hole, until I found this post.
I followed the steps very well and even did them 3 times but still having same issue. I checked with disk utility and the partitions of the usb stick are not bootable when you look at info. Is that normal? Something going wrong? Something needs to be updated with MacOs Monterey? I am dying to be able to play AoE 4 but dont feel like installing windows on my internal ssd :- Thanks for the help! This tut has gotten me the furthest of them all. Hello, I am having the same issue. Is it afterwards possible to use the boot camp external drive on a different windows machine laptop from work and use it there with virtual box?
Even it has been long process and u have done it very well with proper guidance. Thank you bro. System halted. Install bootcamp on mac using bootcamp assistant. Run bootcamp Windows. Download a clone tool I used macrium free. The cloned external drive is now a windows boot drive. You can now remove bootcamp from the internal drive using the bootcamp assistant. Now boot from external drive and resize the bootcamp sector using Windows disk management tools to the full hard-drive size keeping efi sector.
Job done dual boot external Windows tb3 drive. Thanks for this. Do you know what I could be doing wrong here? Do you think deleting the internal bootcamp would resolve that?
Even though I selected EFI, it booted up the internal bootcamp Windows, and not the copy bootcamp Windows on my external drive. Does the step of removing the internal bootcamp Windows force the booting of the external version? When you hold the option key during boot, you should see all drives capable of booting. If you have both an internal bootcamp partition and an external bootcamp drive, you should see both as well as the Mac OS partition.
If you are not seeing the external EFI drive then it is not bootable and something is wrong with it. Thanks for your reply. I get three options: Mac; internal bootcamp; and EFI. When I select EFI, it actually loads up the internal bootcamp.
Are you sure? If you cloned the internal bootcamp partition to the external drive, it will look the same until you make some changes to it, like installing additional applications or UI personalizations. You can also easily tell by opening Windows Disk Manager. Yes, absolutely sure. I loaded up the external version, added something to the desktop.
When I loaded up the internal version, that thing was on the desktop. Appreciate your feedback, folks. There are several mistakes in the description. I have the same problem.
