Last week, Oracle rolled out VirtualBox 6.1.36 along with several bug fixes and improvements. The newest version of the virtualization tool offers support for Linux Kernel 5.18 as well as for the forthcoming Linux Kernel 5.19.
Additionally, VirtualBox 6.1.36 brings Enterprise Linux 9.1 and offers support for Python 3.10. The update reduces the boot time of virtual guests by restricting the Kernel rebuild while it is unnecessary. Following the update, users can now mount the folders represented as a symlink. A few other changes included in the update are:
- VMM: Fixed possible Linux guest kernel crash when configuring Speculative Store Bypass for a single vCPU VM
- GUI: In the storage page of the virtual machine settings dialog, fixed a bug that disrupted mouse interaction with the native file selector on KDE
