Oracle recently fixed several problems in its (open-source) virtualization tool VirtualBox. Version 7.0.20 includes bug fixes for Windows, MacOS, and Linux.
VirtualBox is an open-source virtualization tool from Oracle that allows end users, both (large) companies and technically proficient home users, to run one or more operating systems within another operating system. In doing so, the ‘guest operating systems’ each run in their own virtual environment.
The tool can be used for desktops, servers and embedded applications.
Changes in version 7.0.20
The now-released version 7.0.20 is a maintenance version that has fixed some bugs and other problems. For example, for Windows-based (virtual) ‘guest PCs,’ a bug that shows Trusted Platform Module (TPM)-related errors has been addressed.
Another issue fixed for Windows involves a High-Definition Audio Recording emulation bug for Windows 10 and 11 ‘guests’.
In addition, new UEFT Secure Boot certificates have been added for Windows within VirtualBox 7.0.20. Microsoft has been advising on updates to Secure Boot keys since February this year, and recently, the tech giant released a series of patches for the BlackLotus UEFI Secure Boot security issue.
Other operating systems
Of course, improvements have also been made to the latest edition for other supported operating systems. For example, for macOS guest PCs, a number of USB issues have been fixed, including a USB passing bug for macOS hosts and a USB-related issue generating issues for the Open Host Controller Interface (OHCI).
On the Linux front, the latest version now supports kernels from OpenSuse 15.6 and RHEL 9.5 from Red Hat.
