Some days ago Oracle announced the release of the corrective version of the virtualization system VirtualBox 6.1.36, in which it indicates that 27 corrections have been made.
For those who are unfamiliar with VirtualBox, I can tell you that this is a multiplatform virtualization tool, that gives us the possibility of creating virtual disk drives where we can install an operating system within the one we normally use.
Main new features of VirtualBox 6.1.36
In this new version it is highlighted that fixed possible linux guest kernel crash when enabling protection mode "Speculative storage bypass" for a single vCPU virtual machine.
It is also highlighted that in Linux and Solaris guest environments, issues with configuration handling have been resolved multi-monitor for controllers VBoxVGA and VBoxSVGA, plus the ability to configure the main screen via VBoxManage was provided.
Another change that stands out is that fixed X11 resource leaks during screen resizing and file descriptor changes when starting processes with guest control commands. Fixed issue with launching root processes using guestcontrol.
On the other hand, in Linux and Solaris host environments they allow the mounting of shared directories that are a symbolic link on the host side.
While Linux-based hosts and guests have initial support for Linux kernels 5.18 and 5.19, as well as the development branch of the RHEL 9.1 distribution.
Of the other changes that stand out in this new version:
- Improved support for Linux kernels built with Clang.
- Linux Guest Additions have reduced boot times by eliminating rebuilding of unused modules.
- Fixed a GUI issue when using the mouse in the VM settings dialog when using KDE.
- Improved display update performance when using VBE (VESA BIOS Extensions) mode.
- Fixed a crash that occurs when USB devices are unplugged.
vboximg-mount fixed write issues. - The API offers initial support for Python 3.10.
- Solaris Guest Additions improved the installer and fixed screen size issues in the VMSVGA configuration.
Finally if you are interested in knowing more about it About the release of this patch version of VirtualBox 6.1.36, you can check the details in the following link.
How to install the patch version of VirtualBox in Ubuntu and derivatives?
For those who are already VirtualBox users and they have not yet updated to the new version, they should know that they can only update by opening a terminal and typing the following command in it:
sudo apt update sudo apt upgrade
Now for those who are not yet users, you should know that before installing, they need to ensure that hardware virtualization is enabled. If they are using an Intel processor, they must enable VT-x or VT-d from their computer's BIOS.
In the case of Ubuntu and derivatives, we have two methods to install the application or, where appropriate, update to the new version.
The first method is by downloading the "deb" package offered from the official website of the application. The link is this.
The other method is adding the repository to the system. To add the official VirtualBox package repository, they should open a terminal with Ctrl + Alt + T and run the following command:
echo "deb https://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list
Done this now We must add the public PGP key from the official VirtualBox packages repository to the system.
Otherwise, we will not be able to use the official VirtualBox package repository. To add the public PGP key from the official VirtualBox package repository, run the following command:
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
We must update the APT package repository with the following command:
sudo apt-get update
Once this is done, now we are going to proceed to install VirtualBox to the system with:
sudo apt install virtualbox-6.1
And ready with it, we can use the new version of VirtualBox in our system.
