On one of my development machines I triple-boot so that I can test in a variety of operating environments. I knew that my Linux installation already had publican installed and ready to go publican is a wonderful documentation tool written by Red Hat to facilitate the publishing of DocBook-based documentation and I really did not want to setup a new Fedora VM that duplicated a setup I already had.
To access Apache server on a Virtual Machine from the host machine only , simply execute the following lines on the host:. To use a port lower than on the host machine, changes need to be made to the firewall on that host machine. This can also be set up to work with SSH or any other services by changing "Apache" to the corresponding service and ports.
This is because the connection will be made over a virtual adapter. Recent versions of Virtualbox have support for accelerating OpenGL inside guests. This can be enabled with a simple checkbox in the machine's settings, right below where video ram is set, and installing the Virtualbox guest additions.
However, it is possible to gain accelerated Direct3D in your Windows guests by borrowing the d3d libraries from Wine, which translate d3d calls into OpenGL, which is then accelerated. These libraries are now part of Virtualbox guest additions software. After enabling OpenGL acceleration as described above, reboot the guest into safe mode press F8 before the Windows screen appears but after the Virtualbox screen disappears , and install Virtualbox guest additions, during install enable checkbox "Direct3D support".
Reboot back to normal mode and you should have accelerated Direct3D. However, once the new VMDKs are saved and you move on to another machine, you may experience problems launching an appropriate machine again. To get rid of this issue, you can use the following script to launch VirtualBox.
If you have a dual boot system between Arch Linux and another operating system, it can become tedious to switch back and forth if you need to work in both. You may also experience performance or compatibility issues when using a virtual machine, which can impact your ability to do certain tasks.
This guide will let you reuse, in a virtual machine, your native Arch Linux installation when you are running your second operating system. This way, you keep the ability to run each operating system natively, but have the option to run your Arch Linux installation inside a virtual machine.
Depending on your hard drive setup, device files representing your hard drives may appear differently when you will run your Arch Linux installation natively or in virtual machine. Windows are abstracting the fake RAID device. To circumvent this problem, we will need to use an addressing scheme that is persistent to both systems. This can be achieved using UUIDs. Make sure your boot loader and fstab file is using UUIDs, otherwise fix this issue. Read fstab and Persistent block device naming.
Make sure your mkinitcpio configuration uses the HOOK block :. If it is not present, add it and regenerate the initramfs. Boot the host which will use the Arch Linux virtual machine. The command will need to be adapted according to the host you have.
There are 3 ways to achieve this: login as root, changing the access right of the device with chmod , adding your user to the disk group. The latter way is the more elegant, let us proceed that way:. Adapt the above command to your need, especially the path and filename of the VMDK location and the raw disk location to map which contain your Arch Linux installation.
On Windows, as the disk filename convention is different from UNIX, use this command to determine what drives you have in your Windows system and their location:.
There are other limitations regarding the aforementioned command when used in other operating systems like OS X, please thus read carefully the manual page , if you are concerned.
Then, the newly raw disk needs to be attached to the machine. Indeed, you must specify its hardware configuration as close as possible as your native machine: turning on the 3D acceleration, increasing video memory, setting the network interface, etc. Finally, you may want to seamlessly integrate your Arch Linux with your host operating system and allow copy pasting between both OSes. In some cases it may be useful to install a native Arch Linux system while running another operating system: one way to accomplish this is to perform the installation through VirtualBox on a raw disk.
If the existing operating system is Linux based, you may want to consider following Install from existing Linux instead. This scenario is very similar to Run a native Arch Linux installation inside VirtualBox , but will follow those steps in a different order: start by Create a raw disk. Before starting the VM, run the following commands on the host machine [2] :.
If you are attempting to install Mojave, after doing the aforementioned steps, the installer will load up but you might not be able to send keyboard or mouse input. The reason seems to be that Mojave no longer supports the USB 1.
To do that first install the VirtualBox Extension pack. Input should work from this point onwards. If the installer is unable to properly format the bootable drive during installation and you end up in an UEFI shell, enter the following:.
You will now be brought to couple of obscure PCI paths. The first one is the one that you just attempted to boot from and it did not work. The second or third one should be the one with the MacOS recovery partition that you need to load to continue the installation. Click the second Entry.
If it is empty, press Esc to go back and select the third entry. Once you get one with folders click though the folders. Once you click enter on the boot. Note that some of the subdirectories might be missing. Remember that you need to get to a boot. Your Windows installation must reside on the first MBR partition for this operation to success. Operation for other partitions are available but have been untested see Known limitations for details. The first three following points comes from this outdated VirtualBox wiki page , but are updated here.
Include a reserved system partition if present and the actual Windows partition usually disk C:. The size of Disk2vhd-created image will be the sum of the actual files on the partition used space , not the size of a whole partition.
If all goes well, the image should just boot in a VM and you will not have to go through the hassle with MBR and Windows bootloader, as in the case of cloning an entire partition. If your Windows virtual machine refuses to boot, you may need to apply the following modifications to your virtual machine. When creating the vmdk container, the VirtualBox vboxmanage command supports an mbr option to point to an MBR file. This mechanism allows booting Windows as though booting from the hard drive.
If the VM will be run in full desktop mode, then after successfully booting into the VM, install the Guest Additions to provide better display resolution and to support shared folders.
A VirtualBox shared folder is great for shuffle files between the two operating systems. For systems that do not boot into desktop mode, the GA are not needed.

Introduction There are some caveats with using raw disk access rather than a virtual hard disk. The Windows design is myopic and well known for disrupting existing boot loader configurations. Other considerations: Typically Windows will be installed on at least two hard drive partitions.
The basic approach: Ensure both operating systems boot fine using the respective boot loaders. On the Linux side, create a VM for the Windows operating system. Do not create a virtual hard drive. If available, copy the hard disk MBR as a file. Manually configure the virtual machine to use raw disk access.
Presumptions Both operating systems are installed and dual booting works with no issues. Likewise with optical disk hardware changes. Change the default boot entry to 0 zero. Improve this question.

Thank you. Why can't virtualbox just run the Master boot sector on the selected partition?
This is also what I want to say. Great answer. I used the following in the EFI shell to boot windows: superuser. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name.
