Oracle has released a corrective update for its virtualization system, Virtualbox 7.0.8, which includes 21 bug fixes. In addition, an update has been made available for the last version of Virtualbox 6.1.44 C, which includes four changes such as improving the determination of the use of Systemd and offering support for Linux 6.3 nucleus. It also includes solutions to the assembly of vboxvide with nuclei from Rhel 8.7, 9.1 and 9.2.
Virtualbox 7.0.8 offers several changes, including the ability to turn off the verification of Linux nucleus modules by indicating the vbox_bypass_mudeles_signature_check = “1” parameter in the /etc/vbox/vbox.cfg file and in the /etc/virtoalbox-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-guest-gum systems. The update also includes initial support for the Linux 6.3 nucleus, and experimental support for rebooting the nucleus and user services modules and user services for guest systems based on Linux after updating the Guest Additions.
Other significant updates include the ability to add MOK (Machine Owner Key) to NVRAM using the Vboxmanage Modifynvram Enrolmok command and supporting digital signatures to the MOK list through API. Improvements have also been made to the use of SystemD to initialize the system for guest systems based on Linux.
Additionally, the update solves problems with the assembly of the Vboxvideo module when using nuclei from the composition RHEL 8.7, 9.1, and 9.2. It also improves the support for invested launch of virtual machines in the manager of virtual machines.
The update has also resolved issues related to the use of the Hyper-V hypervisor, problems with graphics manifested when using guest systems with Windows 7, problems with the recording of the port values in the USB-filters editor and VM name and OS type editing. Furthermore, it has refined the launch of guest systems with UEFI using MacOS 13.3+ and issues with the Oracle VM Virtualbox Extension Pack providing a cryptographic module for encryption of virtual machines.
Overall, the update aims to increase the flexibility, security and overall effectiveness of Virtualbox.
