This displays the Virtual Media Manager, described in. Once Windows is installed, the Windows desktop will be displayed. This can be useful to temporarily start another machine, or in more complicated environments, for sophisticated memory management of many virtual machines that may be running in parallel depending on how memory is used by the guests.

These include automatic resizing, seamless mode, the bidirectional clipboard, drag and drop, and generally better performance. This procedure gets down to the basics.
One of such containable parts is Guest Additions package. Thanks for contributing an answer to Ask Different! This procedure gets down to the basics. You can copy and move files from a guest to the host system or from the host system to the guest. Search for a free drive letter, starting at Z:. Drivers for 3D hardware are generally too complex to be made properly secure and any software which is allowed to access them may be able to compromise the operating system running them. The Guest Additions enable you to control and monitor guest execution.
macosx - Petr Dvorak, thank you very much for your help and for posting this blog. Click Close to end the guest session.
This chapter describes the Guest Additions in detail. Introduction to Guest Additions As mentioned inthe Guest Additions are designed to be installed inside guest additions virtualbox mac virtual machine after the guest operating system has been installed. They consist of device drivers and system applications that optimize the guest operating system for better performance and usability. To overcome the limitations for mouse support described inthis feature provides you with seamless mouse support. These provide an easy way to exchange files between the host and the guest. In addition, with Windows, Linux, and Oracle Solaris guests, you can resize the virtual machine's window if the Guest Additions are installed. The video resolution in the guest will be automatically adjusted, as if you had manually entered an arbitrary resolution in the guest's Display settings. If the Guest Additions are installed, 3D graphics and 2D video for guest applications can be accelerated. With this feature, the individual windows that are displayed on the desktop of the virtual machine can be mapped on the host's desktop, as if the underlying application was actually running on the host. The Guest Additions enable you to control and monitor guest execution. Additionally, applications can be started in a guest from the host. For various reasons, the time in the guest might run at a slightly different rate than the time on the host. The Guest Additions will resynchronize the time regularly. See for how to configure the parameters of the time synchronization mechanism. With the Guest Additions installed, the clipboard of the guest operating system can optionally be shared with your host operating system. The Windows and Linux Guest Additions therefore check automatically whether they have to be updated. A Windows guest should then automatically start the Guest Additions installer, which installs the Guest Additions on your Windows guest. This displays the Virtual Media Manager, guest additions virtualbox mac in. The installer will add several device drivers to the Windows driver database and then invoke the hardware detection wizard. Depending on your configuration, it might display warnings that the drivers are not digitally signed. You must confirm these in order to continue the installation and properly install the Additions. After installation, reboot your guest operating system to activate the Additions. Updating the Windows Guest Additions Windows Guest Additions can be updated by running the installation program again. This replaces the previous Additions drivers with updated versions. Alternatively, you can also open the Windows Device Manager and select Update Driver. Failure to do this will cause a typical Windows installation to display multiple dialogs asking guest additions virtualbox mac you want to install a particular driver. Installing the code signing certificates on a Windows guest can be done automatically. When installing the same certificate more than once, an appropriate error will be displayed. This is only required for Vista and Windows 7. The Guest Additions work in those distributions. It is highly recommended to take a snapshot of the virtual machine before replacing preinstalled Guest Additions. They also come with an installation program that guides you through the setup process. However, due to the significant differences between Linux distributions, installation may be slightly more complex when compared to Windows. This works as described inexcept that this step must be performed in your Linux guest instead of on a Linux host system. During the installation process, the X. Org display server will be set up to use the graphics and mouse drivers which come with the Guest Additions. Multiple guest monitors are supported in guests using the X. The layout of the guest screens can be adjusted as needed using the tools which come with the guest operating system. If you want to understand more about the details of how the X. Org drivers are set up, in particular if you wish to use them in a setting which guest additions virtualbox mac installer does not handle correctly, see. In particular, if the Additions version installed or the guest operating system were very old, or if you made your own changes to the Guest Additions setup after you installed them. The following Oracle Solaris distributions are officially supported: 4. They come with an installation program that guides you through the setup process. After the installation is complete, log out and log in to X server on your guest, to guest additions virtualbox mac the X11 Guest Additions. We do not provide an automatic installer at this time. This is similar to how you would use network shares in Windows networks, except that shared folders do not require networking, only the Guest Additions. Shared folders are supported with Windows 2000 or later, Linux, and Oracle Solaris guests. Shared folders physically reside on the host and are then shared with the guest, which uses a special file system driver in the Guest Additions to talk to the host. For Windows guests, shared folders are implemented as a pseudo-network redirector. For Linux and Oracle Solaris guests, the Guest Additions provide a virtual file system. This happens on the host. In the guest you can then use the share name to connect to it and access files. Shared folders can either be read-write or read-only. This means that the guest is either allowed to both read and write, or just read files on the host. By default, shared folders are read-write. By right-clicking on a shared folder and selecting Map Network Drive from the menu that pops up, you can assign a drive letter to that shared folder. The usual mount rules apply. For example, create this directory first if it does not exist yet. The generic mount options, documented in the mount manual page, apply also. When automatic mounting is enabled for a shared folder, the Guest Additions service will mount it for you automatically. For Linux or Oracle Solaris, a mount point directory can also be specified. If a drive letter or mount point is not specified, or is in use already, an alternative location is found by the Guest Additions service. Search for a free drive letter, starting at Z:. If all drive letters are assigned, the folder is not mounted. Access to an automatically mounted shared folder is granted to everyone in a Windows guest, including the guest user. For Linux and Oracle Solaris guests, access is restricted to members of the group vboxsf and the root user. For this to work the latest Guest Additions must be installed on the guest. Drag and drop transparently allows copying or opening files, directories, and even certain clipboard formats from one end to the other. For example, from the host to the guest or from the guest to the host. At the moment drag and drop is implemented for Windows-based and X-Windows-based systems, both on the host and guest side. In the context of using drag and drop, the origin of the data is called the source. That is, where the actual data comes from and is specified. The target specifies where the data from the source should go to. Transferring data from the source to the target can be done in various ways, such as copying, moving, or linking. Note At the moment only copying of data is supported. Moving or linking is not yet implemented. Disables the drag and drop feature entirely. Enables drag and drop operations from the host to the guest only. Enables drag and drop operations from the guest to the host only. Enables drag and drop operations in both directions: from the host to the guest, and from the guest to the host. Note Drag and drop support depends on the frontend being used. At the moment, only the VirtualBox Manager frontend provides this functionality. This guest additions virtualbox mac so that the target operating system, which receiving the data, is able to handle them in an appropriate manner. This works for all supported host platforms, provided that your host operating system can make use of your accelerated 3D hardware in the first place. As a result, the Guest Additions installation program offers Direct3D acceleration as an option that must be explicitly enabled. Also, you must install the Guest Additions in Safe Mode. Drivers for 3D hardware are generally too complex to be made properly secure and any software which is allowed to access them may be able to compromise the operating system running them. The Aero theme is not enabled by default. Select any Aero theme in the Personalization window. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is capable of 3D hardware acceleration. To enable seamless mode, after starting the virtual machine, press the Host key + L. The Host key is normally the right control key. This works in both directions. Guest properties are simply string keys to which a value is attached. They can be set, or written to, by either the host and the guest. They can also be read from both sides. Some of this runtime information is shown when you select Session Information Dialog from a virtual machine's Machine menu. The left pane shows the files on the host system. At the bottom of the Guest Control File Manager, enter authentication credentials for a user on the guest system. You can copy and move files from a guest to the host system or from the host system to the guest. Click Close to end the guest session. For this to work, the application needs to be installed inside the guest. No additional software needs to be installed on the host. Additionally, text mode output to stdout and stderr can be shown on the host for further processing. There are options to specify user credentials and a timeout value, in milliseconds, to limit the time the application is able to run. This feature can be used to automate deployment of software within the guest. The Guest Additions for Windows allow for automatic updating. This applies for already installed Guest Additions version 4. Also, copying files from host to the guest as well as remotely creating guest directories is available. With memory ballooning, memory that was allocated for a virtual machine can be given to another virtual machine without having to shut the machine down. This ensures that the guest will not use that memory any longer. No guest applications can allocate it, and the guest kernel will not use it either. It is guest additions virtualbox mac returned as free memory to the host. Requesting balloon memory from a running guest will therefore not increase the amount of free, unallocated memory on the host. Effectively, memory ballooning is therefore a memory overcommitment mechanism for multiple virtual machines while they are running. This can be useful to temporarily start another machine, or in more complicated environments, for sophisticated memory management of many virtual machines that may be running in parallel depending on how memory is used by the guests. Page Fusion currently works only with Windows 2000 and later guests. This guest additions virtualbox mac called copy on write. All this is fully transparent to the virtual machine. You may be familiar with this kind of memory overcommitment from other hypervisor products, which call this feature page sharing or same page merging. Then, they look for pages with identical hashes and compare the entire content of those pages. If two pages produce the same hash, it is very likely that the pages are identical in content. This process can take rather long, especially if the system is not idling. As a result, the additional memory only becomes available after a significant amount of time, such as hours or sometimes days. It can therefore achieve most of the possible savings of page sharing almost immediately and with almost no overhead. See for information on how to query metrics.
