• VirtualBox 6.0 provides a new setting called Graphics Controller. There are four options to choose from: None; VBoxVGA; VMSVGA; VBoxSVGA; In the user manual I have found this information: Graphics Controller: Specifies the graphics adapter type used by the guest VM.
• Oracle VM VirtualBox also ships with a set of drivers that improve running OS/2 in a virtual machine. Due to restrictions of OS/2 itself, this variant of the Guest Additions has a limited feature set. See Known Limitations for details. The OS/2 Guest Additions are provided on.
• Mac OS X hosts. Functionality is limited when using AirPort, the Mac's wireless networking system, for bridged networking. Currently, Oracle VM VirtualBox supports only IPv4 and IPv6 over AirPort. For other protocols, such as IPX, you must choose a wired interface.
• Oracle VirtualBox has some limited options about the VM's graphics, and I can't choose which graphics card to emulate. When installing an OS on a VM, it's autodetected as Standard VGA. I can manually make the OS use the generic SVGA driver, which works, but still has rather limited modes: 1024x768 with up to 256 colours and 800x600 with up to.

Virtualbox Macos Graphics Driver

Jun 24, 2018  VMQemuVGA display adapter driver for OSx86 running as a VirtualBox guest. The binary should work on all OSs from Snow Leopard up to Yosemite 10.10. It allows to set different screen resolutions in VirtualBox from System Preferences. The changes I've made to.

Virtualbox Mac Os Video Driver

The following section describes known problems with this release of Oracle VM VirtualBox. Unless marked otherwise, these issues are planned to be fixed in later releases.

Install Mac Os On Virtualbox

• The following Guest SMP (multiprocessor) limitations exist:

  • Poor performance with 32-bit guests on AMD CPUs. This affects mainly Windows and Oracle Solaris guests, but possibly also some Linux kernel revisions. Partially solved for 32-bit Windows NT, 2000, XP, and 2003 guests. Requires the Guest Additions to be installed.

  • Poor performance with 32-bit guests on certain Intel CPU models that do not include virtual APIC hardware optimization support. This affects mainly Windows and Oracle Solaris guests, but possibly also some Linux kernel revisions. Partially solved for 32-bit Windows NT, 2000, XP, and 2003 guests. Requires the Guest Additions to be installed.

• NX (no execute, data execution prevention) only works for guests running on 64-bit hosts and requires that hardware virtualization be enabled.

• Guest control. On Windows guests, a process started using the guest control execute support will not be able to display a graphical user interface unless the user account under which it is running is currently logged in and has a desktop session.

  Also, to use accounts without or with an empty password, the guest's group policy must be changed. To do so, open the group policy editor on the command line by typing gpedit.msc, open the key Computer ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity Options and change the value of Accounts: Limit local account use of blank passwords to console logon only to Disabled.

• Compacting virtual disk images is limited to VDI files. The VBoxManage modifymedium --compact command is currently only implemented for VDI files. At the moment the only way to optimize the size of a virtual disk images in other formats, such as VMDK or VHD, is to clone the image and then use the cloned image in the VM configuration.

• OVF import/export:

  • OVF localization, with multiple languages in a single OVF file, is not yet supported.

  • Some OVF sections like StartupSection, DeploymentOptionSection, and InstallSection are ignored.

  • OVF environment documents, including their property sections and appliance configuration with ISO images, are not yet supported.

  • Remote files using HTTP or other mechanisms are not yet supported.

• Neither scale mode nor seamless mode work correctly with guests using OpenGL 3D features, such as with Compiz-enabled window managers.

• The RDP server in the Oracle VM VirtualBox extension pack supports only audio streams in format 22.05kHz stereo 16-bit. If the RDP client requests any other audio format there will be no audio.

• Preserving the aspect ratio in scale mode works only on Windows hosts and on Mac OS X hosts.

• On Mac OS X hosts, the following features are not yet implemented:

  • Numlock emulation

  • CPU frequency metric

  • Memory ballooning

• Mac OS X guests:

  • Mac OS X guests can only run on a certain host hardware. For details about license and host hardware limitations. See Section 3.1.1, “Mac OS X Guests” and check the Apple software license conditions.

  • Oracle VM VirtualBox does not provide Guest Additions for Mac OS X at this time.

  • The graphics resolution currently defaults to 1024x768 as Mac OS X falls back to the built-in EFI display support. See Section 3.14.1, “Video Modes in EFI” for more information on how to change EFI video modes.

  • Mac OS X guests only work with one CPU assigned to the VM. Support for SMP will be provided in a future release.

  • Depending on your system and version of Mac OS X, you might experience guest hangs after some time. This can be fixed by turning off energy saving. Set the timeout to 'Never' in the system preferences.

  • By default, the Oracle VM VirtualBox EFI enables debug output of the Mac OS X kernel to help you diagnose boot problems. Note that there is a lot of output and not all errors are fatal. They would also show when using a physical Apple Macintosh computer. You can turn off these messages by using the following command:

    To revert to the previous behavior, use the following command:

  • It is currently not possible to start a Mac OS X guest in safe mode by specifying the -x option in VBoxInternal2/EfiBootArgs extradata.

• Oracle Solaris hosts:

  • USB support on Oracle Solaris hosts requires Oracle Solaris 11 version snv_124 or later. Webcams and other isochronous devices are known to have poor performance.

  • Host Webcam passthrough is restricted to 640x480 frames at 20 frames per second due to limitations in the Oracle Solaris V4L2 API. This may be addressed in a future Oracle Solaris release.

  • No ACPI information, such as battery status or power source, is reported to the guest.

  • No support for using wireless adapters with bridged networking.

  • Crossbow-based bridged networking on Oracle Solaris 11 hosts does not work directly with aggregate links. However, you can use dladm to manually create a VNIC over the aggregate link and use that with a VM. This limitation does not exist in Oracle Solaris 11u1 build 17 and later.

• Neither virtio nor Intel PRO/1000 drivers for Windows XP guests support segmentation offloading. Therefore Windows XP guests have slower transmission rates comparing to other guest types. Refer to MS Knowledge base article 842264 for additional information.

• Guest Additions for OS/2. Seamless windows and automatic guest resizing will probably never be implemented due to inherent limitations of the OS/2 graphics system.

• Some guest operating systems predating ATAPI CD-ROMs may exhibit long delays or entirely fail to boot in certain configurations. This is most likely to happen when an IDE/ATAPI CD-ROM exists alone on a primary or secondary IDE channel.

  Affected operating systems are MS OS/2 1.21: fails to boot with an error message referencing COUNTRY.SYS and MS OS/2 1.3: long boot delays. To avoid such problems, disable the emulated IDE/ATAPI CD-ROM. The guest OS cannot use this device, anyway.
