You actually got it to install on VirtualBox? Just pick windows 8 NOT OTHERS as the vm type on a suitable host. Also runs fine on KVM, and vmware. Journeyman Geek: For me, it installed using Other Windows as the VM type i. Maybe the host OS matters? I use Kbuntu Maybe cause I'm running a 64 bit guest on a 64 bit system on mine. JourneymanGeek He's specifically asking about the installing the VirtualBox Guest Additions in the guest, not installing the OS in a VM.

Thank you. VitualBox 4. Do you know, why checking for a new version from VirtualBox menu shows me that latest version is already installed, but it is not? For Macbook Pro running OSX exe in the Windows 10 VM, choose properties and set the compatibility to Windows 7. Then "Direct 3D Support Experimental " won't be checked and you can proceed without install error.

This feature can be used to automate deployment of software within the guest. For this to work, the application needs to be installed on 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. The Guest Additions for Windows allow for automatic updating.

This applies for already installed Guest Additions versions. Also, copying files from host to the guest as well as remotely creating guest directories is available. To use these features, use the Oracle VM VirtualBox command line. In server environments with many VMs, the Guest Additions can be used to share physical host memory between several VMs. This reduces the total amount of memory in use by the VMs. If memory usage is the limiting factor and CPU resources are still available, this can help with running more VMs on each host. The Guest Additions can change the amount of host memory that a VM uses, while the machine is running. Because of how this is implemented, this feature is called memory ballooning. Oracle VM VirtualBox supports memory ballooning only on bit hosts. It is not supported on macOS hosts. Memory ballooning does not work well with large pages enabled.

To turn off large pages support for a VM, run VBoxManage modifyvm vmname --large-pages off. Normally, to change the amount of memory allocated to a virtual machine, you have to shut down the virtual machine entirely and modify its settings. 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. When memory ballooning is requested, the Oracle VM VirtualBox Guest Additions, which run inside the guest, allocate physical memory from the guest operating system on the kernel level and lock this memory down in the guest. 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.

Oracle VM VirtualBox can then reuse this memory and give it to another virtual machine. The memory made available through the ballooning mechanism is only available for reuse by Oracle VM VirtualBox. It is not 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. At this time, memory ballooning is only supported through VBoxManage.

Use the following command to increase or decrease the size of the memory balloon within a running virtual machine that has Guest Additions installed:. where VM name is the name or UUID of the virtual machine in question and n is the amount of memory to allocate from the guest in megabytes. You can also set a default balloon that will automatically be requested from the VM every time after it has started up with the following command:. By default, no balloon memory is allocated. This is a VM setting, like other modifyvm settings, and therefore can only be set while the machine is shut down. Whereas memory ballooning simply reduces the amount of RAM that is available to a VM, Page Fusion works differently. It avoids memory duplication between several similar running VMs. In a server environment running several similar VMs on the same host, lots of memory pages are identical.

For example, if the VMs are using identical operating systems. Oracle VM VirtualBox's Page Fusion technology can efficiently identify these identical memory pages and share them between multiple VMs. Oracle VM VirtualBox supports Page Fusion only on bit hosts, and it is not supported on macOS hosts. Page Fusion currently works only with Windows and later guests. The more similar the VMs on a given host are, the more efficiently Page Fusion can reduce the amount of host memory that is in use. It therefore works best if all VMs on a host run identical operating systems. Instead of having a complete copy of each operating system in each VM, Page Fusion identifies the identical memory pages in use by these operating systems and eliminates the duplicates, sharing host memory between several machines. This is called deduplication.

If a VM tries to modify a page that has been shared with other VMs, a new page is allocated again for that VM with a copy of the shared page. This is 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. However, Page Fusion differs significantly from those other solutions, whose approaches have several drawbacks:. Traditional hypervisors scan all guest memory and compute checksums, also called hashes, for every single memory page. 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.

Page Fusion in Oracle VM VirtualBox uses logic in the Oracle VM VirtualBox Guest Additions to quickly identify memory cells that are most likely identical across VMs. It can therefore achieve most of the possible savings of page sharing almost immediately and with almost no overhead. Page Fusion is also much less likely to be confused by identical memory that it will eliminate, just to learn seconds later that the memory will now change and having to perform a highly expensive and often service-disrupting reallocation. At this time, Page Fusion can only be controlled with VBoxManage , and only while a VM is shut down.

To enable Page Fusion for a VM, use the following command:. You can observe Page Fusion operation using some metrics. Enabling Page Fusion might indirectly increase the chances for malicious guests to successfully attack other VMs running on the same host. See Section The Guest Additions provide services for controlling the guest system's monitor topology. The resolution of a virtual monitor can be modified from the host side either by resizing the window that hosts the virtual monitor, by using the View menu or the VBoxManage controlvm vmname setscreenlayout command. The following are some details about guest screen resolution control functionality:. On X11 desktops VBoxClient --vmsvga handles screen topology through the RandR extension. On Wayland clients VBoxDRMClient is used. The decision is made automatically at each desktop session start. On bit guest operating systems VBoxDRMClient is always used, in order to work around bugs.

Since the monitor topology control services are initialized during the desktop session start, it is impossible to control the monitor resolution of display managers such as GDM or LightDM. When this guest property is set then VBoxDRMClient is started during the guest OS boot and stays active all the time, for both the display manager login screen and the desktop session. VBoxDRMClient is not able to handle arbitrary guest monitor topologies. Specifically, disabling a guest monitor that is not the last one invalidates the monitor topology due to limitations in the vmwgfx. ko Linux kernel module. For example, when the guest is configured to have four monitors it is not recommended to disable the second or third monitor. Chapter 4. Guest Additions. Table of Contents 4.

Re: Where to download Guest Additions ISO by multiOS » Wed Sep 18, am You don't download it separately. It's included in the VirtualBox installation download. I suggest you try reading the User Guide which is also in the download and available through the Help Menu as well as online. It's explained very clearly. This is a User Forum and I would suggest you lose the attitude very quickly if you expect help from other users. Re: Where to download Guest Additions ISO by BillG » Wed Sep 18, am When you click on Insert Guest Additions CD image the image is assigned to the optical drive of your vm.

What happens after that depends on how your guest OS is configured. What OS is running in the guest? Have you made any attempt to run the Guest Additions from within the guest after you attached the CD image?

Re: Where to download Guest Additions ISO by scottgus1 » Fri Oct 04, pm wfouche, it is not good to go downloading GAs besides the version that comes with the Virtualbox installer. Software that has to work with partner software has to know what the partner is doing. As the developers update capabilities they put these capabilities in both the main Virtualbox and the GAs ISO. If you change the GAs to a newer version with different capabilities, the host Virtualbox software won't know what the GAs are doing and problems will develop.

Allowing the GAs to fall behind the main VB version isn't bad for a while. But having the GAs be ahead of the main VB, that could go pear-shaped soon. As an example, when the GAs were causing shared folder issues recently, the devs didn't put out just new GAs, they put out a whole test-build of the entire Virtualbox program, GAs included. Don't allow installing of new GAs without installing the matching version of Virtualbox. And use the ISO that came with Virtualbox t o install the GAs. Board index All times are UTC.

Controlling Virtual Monitor Topology. 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. But having the GAs be ahead of the main VB, that could go pear-shaped soon. This tool is included in the Guest Additions.
