After a year of development, Oracle virtualization system release . Ready installation packages for Linux (Ubuntu, Fedora, openSUSE, Debian, SLES, RHEL in builds for the AMD64 architecture), Solaris, macOS and Windows.
All :
- Added support for hardware mechanisms proposed in the fifth generation of Intel Core i (Broadwell) processors for organizing nested launch of virtual machines;
- The old method of supporting 3D graphics, based on the VBoxVGA driver, has been removed. For 3D it is recommended to use the new VBoxSVGA and VMSVGA drivers;
- The VBoxSVGA and VMSVGA drivers have added support for YUV2 and texture formats using this color model when using OpenGL on the host side (in macOS and Linux), which allows, when 3D is enabled, to provide faster video display by moving color space conversion operations to the GPU side. Problems with compressed textures in OpenGL when using 3D mode in the VMSVGA driver have been resolved;
- Added a software on-screen keyboard with support for multimedia keys, which can be used as a keyboard in guest OSes;
- Added the vboximg-mount module with experimental support for direct access to NTFS, FAT and ext2/3/4 file systems inside a disk image, implemented on the guest system side and not requiring support for this file system on the host side. Work is still possible in read-only mode;
- Added experimental support for virtio-scsi, both for hard drives and optical drives, including the ability to boot from a virtio-scsi-based device;
- Added an option to export virtual machines to cloud environments that use the paravirtualization mechanism;
- Support for the recompiler has been discontinued; running virtual machines now requires support for hardware virtualization in the CPU;
- The graphical interface has improved the creation of virtual machine images (VISO) and expanded the capabilities of the built-in file manager;
- A built-in VM attribute editor has been added to the panel with information about the virtual machine, allowing you to change some settings without opening the configurator;
- The convenience of configuring storage parameters for a VM has been improved, support for changing the controller bus type has been provided, and the ability to move attached elements between controllers using the drag&drop interface has been provided.
- The dialog with session information has been expanded and improved;
- The media selection dialog has been optimized, showing both a list of known images and allowing you to select an arbitrary file;
- The interface for setting up storages and the network subsystem has been optimized;
- Added CPU load indicator to the status bar in the virtual machine;
- The media enumeration code has been optimized to work faster and load less on the CPU in situations where there are a large number of registered media. The ability to add existing or new media has returned to Virtual Media Manager;
- VirtualBox Manager has improved the display of the list of virtual machines, groups of virtual machines are more prominently highlighted, the search for VMs has been improved, and the tool area has been pinned to fix the position when scrolling the list of VMs;
- There is now support for importing virtual machines from Oracle Cloud Infrastructure. The functionality for exporting virtual machines to Oracle Cloud Infrastructure has been expanded, including the ability to create multiple virtual machines without downloading them again. Added the ability to link arbitrary tags to cloud images;
- In the input system, support for horizontal mouse scrolling has been added using the IntelliMouse Explorer protocol;
- Runtime is adapted to work on hosts with a large number of CPUs (no more than 1024);
- Added the ability to change the sound backend running on the host side when the VM is in a saved state;
- Added support to VBoxManager for moving multiple guest source files/directories to a target directory;
- Added support for Linux kernel 5.4. When building the kernel, the generation of digital signatures for modules is disabled (signatures can be added by the user after the build is completed). The function of forwarding PCI devices in Linux has been removed, since the current code is not completed and is not suitable for use;
- The EFI implementation has been moved to newer firmware code, and NVRAM support has been added. Added support for loading from
APFS and the ability to use non-standard paths to boot devices with SATA and NVMe interfaces created in macOS; - Added a new type of network adapter PCnet-ISA (currently only available from the CLI);
- Improved implementation of the USB EHCI controller. Added the ability to filter USB devices by connection port.
