Windows is particularly picky about its boot devices, and migrating VMs between hypervisors is very difficult or impossible if the storage controllers are different. Note that for Windows 7 guests, 3rd party drivers must be installed for xHCI support. In the Settings window, under General , you can configure the most fundamental aspects of the virtual machine such as memory and essential hardware.

The following tabs are available. In the Basic tab of the General settings category, you can find these settings:. As a result, you can only use characters which are allowed in your host OS's file names. You can display these with VBoxManage. This is the same setting that is specified in the New Virtual Machine wizard.

Whereas the default settings of a newly created VM depend on the selected OS type, changing the type later has no effect on VM settings. This value is purely informational and decorative. The following settings are available in the Advanced tab:. With this setting, you can specify any other folder for each VM. Shared Clipboard: You can select here whether the clipboard of the guest OS should be shared with that of your host. If you select Bidirectional , then Oracle VM VirtualBox will always make sure that both clipboards contain the same data. In such a case, this setting has no effect.

For security reasons, the shared clipboard is disabled by default. This setting can be changed at any time using the Shared Clipboard menu item in the Devices menu of the virtual machine. Drag and Drop: This setting enables support for drag and drop.

Select an object, such as a file, from the host or guest and directly copy or open it on the guest or host. Multiple per-VM drag and drop modes allow restricting access in either direction. For drag and drop to work the Guest Additions need to be installed on the guest. Drag and drop is disabled by default. This setting can be changed at any time using the Drag and Drop menu item in the Devices menu of the virtual machine.

On the Description tab you can enter a description for your virtual machine. This has no effect on the functionality of the machine, but you may find this space useful to note down things such as the configuration of a virtual machine and the software that has been installed into it.

The Disk Encryption tab enables you to encrypt disks that are attached to the virtual machine. To enable disk encryption, select the Enable Disk Encryption check box. Settings are available to configure the cipher used for encryption and the encryption password. The System category groups various settings that are related to the basic hardware that is presented to the virtual machine.

About virtual machines

As the activation mechanism of Microsoft Windows is sensitive to hardware changes, if you are changing hardware settings for a Windows guest, some of these changes may trigger a request for another activation with Microsoft. On the Motherboard tab, you can configure virtual hardware that would normally be on the motherboard of a real computer.

The specified amount of memory will be requested from the host OS, so it must be available or made available as free memory on the host when attempting to start the VM and will not be available to the host while the VM is running. Generally, it is possible to change the memory size after installing the guest OS. But you must not reduce the memory to an amount where the OS would no longer boot. Boot Order: Determines the order in which the guest OS will attempt to boot from the various virtual boot devices. This needs to be configured in detail on the command line.

Chipset: You can select which chipset will be presented to the virtual machine. Note that the ICH9 support is experimental and not recommended for guest OSes which do not require it. Using the virtual USB tablet has the advantage that movements are reported in absolute coordinates, instead of as relative position changes.

This makes using the VM less tedious even if Guest Additions are not installed. It is also required if you want to use more than one virtual CPU in a virtual machine. Turning it on after installation will have no effect however. ACPI is the current industry standard to allow OSes to recognize hardware, configure motherboards and other devices and manage power. ACPI can only be turned off using the command line. However, turning it on after installation will have no effect.

On the Processor tab, you can configure settings for the CPU used by the virtual machine. You should not configure virtual machines to use more CPU cores than are available physically. This includes real cores, with no hyperthreads. Note that limiting the execution time of the virtual CPUs may cause guest timing problems. A warning is displayed at the bottom of the Processor tab if an Execution Cap setting is made that may affect system performance. This is made possible by adding another 4 bits to memory addresses, so that with 36 bits, up to 64 GB can be addressed.

For Intel CPUs, the option is grayed out.

Paravirtualization Interface: Oracle VM VirtualBox provides paravirtualization interfaces to improve time-keeping accuracy and performance of guest OSes. Hardware Virtualization: You can select for each virtual machine individually whether Oracle VM VirtualBox should use software or hardware virtualization. Advanced users may be interested in technical details about software versus hardware virtualization. In most cases, the default settings on the Acceleration tab will work well.

How to Create an Ubuntu Virtual Machine With VirtualBox (Mac)

Oracle VM VirtualBox selects sensible defaults, depending on the OS that you selected when you created the virtual machine. In certain situations, however, you may want to change the preconfigured defaults. Video Memory: Sets the size of the memory provided by the virtual graphics card available to the guest, in MB. As with the main memory, the specified amount will be allocated from the host's resident memory.

Based on the amount of video memory, higher resolutions and color depths may be available. The GUI will show a warning if the amount of video memory is too small to be able to switch the VM into full screen mode. The minimum value depends on the number of virtual monitors, the screen resolution and the color depth of the host display as well as on the use of 3D acceleration and 2D video acceleration. Extra memory may be required if display acceleration is used. Up to eight such virtual monitors are supported. The output of the multiple monitors are displayed on the host in multiple VM windows which are running side by side.

However, in full screen and seamless mode, they use the available physical monitors attached to the host. As a result, for full screen and seamless modes to work with multiple monitors, you will need at least as many physical monitors as you have virtual monitors configured, or Oracle VM VirtualBox will report an error. • View topic - Extracting a .VDI on a mac.

Scale Factor: Enables scaling of the display size. For multiple monitor displays, you can set the scale factor for individual monitors, or globally for all of the monitors. You can set a default scale factor for all VMs. Use the Display tab in the Global Settings dialogs. Enable 3D Acceleration: If a virtual machine has Guest Additions installed, you can select here whether the guest should support accelerated 3D graphics.

Enable 2D Video Acceleration: If a virtual machine with Microsoft Windows has Guest Additions installed, you can select here whether the guest should support accelerated 2D video graphics. Graphics Controller: Specifies the graphics adapter type used by the guest VM.

The following options are available:. This is the default graphics controller for Windows versions before Windows 7 and for Oracle Solaris. This is the default graphics controller for Linux guests.

None: Does not emulate a graphics adapter type. This enables you to connect to the console of the virtual machine remotely with any standard RDP viewer, such as mstsc. On Linux and Oracle Solaris systems you can use the standard open source rdesktop program. Enable Server: Select this check box and configure settings for the remote display connection. On the Recording tab you can enable video and audio recording for a virtual machine and change related settings. Note that these features can be enabled and disabled while a VM is running. Enable Recording: Select this check box and select a Recording Mode option.

Recording Mode: You can choose to record video, audio, or both video and audio. Some settings on the Recording tab may be grayed out, depending on the Recording Mode setting. File Path: The file where the recording is saved. Frame Size: The video resolution of the recorded video, in pixels. The drop-down list enables you to select from common frame sizes.
