Coming three months after VirtualBox 7.0.8, the new release adds initial support for the Linux 6.4 kernel series for both guests and hosts, initial support for the upcoming Linux 6.5 kernel series only for hosts. Proceed as follows per official Oracle's instructions

Acivate on system following repo $ sudo dnf copr enable jforbes/kernel-stabilization and upgrade system via $ sudo dnf update -y . Make sure that kernel 6.4.2-201 has been installed:

[boris@ServerFedora38 ~]$ rpm -qa | grep kernel | grep "6.4.2" => kernel-devel-6.4.2-201.fc38.x86_64 kernel-devel-matched-6.4.2-201.fc38.x86_64 kernel-6.4.2-201.fc38.x86_64 . . . Now setup rpmfusion . . . .

Just one notice regarding current review. Quoting mentioned "Howto" : Officially, Windows 11 requires Secure Boot and TPM 2.0. These features are not (yet) available in VirtualBox. The result is that you will get the error as you can see on the right image. Important note for Windows 11:

To bypass these settings, click on the X icon at the right upper corner and quit the setup. Hold the SHIFT key and press F10. Then give the command ‘regedit’. Navigate to HKEY_LOCAL_MACHINESYSTEMSetup and create a new key (folder) here named ‘LabConfig’. Within this key, create a new DWORD (32 bits) value named ‘BypassSecureBootCheck’. Create another DWORD (32 bits) value named ‘BypassTPMCheck’. Don’t forget to set both values to 1.

Post below was inspired by article "How to install Windows 11 in a VirtualBox with Ubuntu Linux as host" . In particular, mentioned "Howto" suggests a known registry hack descscribed in section "Important note for Windows 11" . Down here follows another aproach, proposed in http://lxer.com/module/newswire/view/331458/index.html for KVM Hypervisor, it is supposed to be applied to Virtualbox 7.0. Once again we intend to work via "alien" conversion on Ubuntu 22.04 and SparkyLinux 7 .

Conversion via "alien" utility virtio-win-0.1.229-1.noarch.rpm to debian format (*.deb) and deploying virtio-win_0.1.229-1_all.deb on SparkyLinux 7 allows straightforward install Windows 11 KVM Guest in UEFI mode on SparkyLinux 7 and Debian BookWorm as well .

First of all make sure that packages : $ sudo apt install ovmf swtpm swtpm-tools are already installed on your system, then the configuration of TPM is no longer your concern. Howevere, original setup would still look like . . . . . .

Virt-manager still appears to be the most powerful tool in regards of deployment and managment of KVM guests. Also sometimes it seems to be more functional rather then Cockpit Web console, in my very personal opinion. In particular, it allows to configure some features required by Windows 11 KVM Guest in the most recent builds of Fedora Linux 38,37.

Brief instruction for setting up Virt-manager to perform straightforward installation of Windows 11 KVM Guest on Fedora 38 Workstation under 6.3.4 kernel.

To make system ready for VitualBox 7 setup via rpmfusion repos,install the Linux kernel "header" files matching the current kernel for adding new hardware support to the system. The distribution packages containing the headers is probably: kernel-devel-6.0.9-300.fc37. Kernel packages installation has been done as follows.

Central limit theorems (CLT) are a class of theorems in probability theory stating that the sum of a sufficiently large number of weakly dependent random variables that have approximately the same scale (none of the terms dominates, does not make a decisive contribution to the sum), has a distribution close to normal.

We intend to rely on https://github.com/mathbunnyru/python-cpp-extension . We also would convert lists to sets and vice-versa and utilize method set1.difference(set2) . Sometimes Python tricks make you really excited

This post is an immediate follow up for http://lxer.com/module/newswire/view/306255/index.html what will result significant performance boost vs python's version of the sieve of Eratosthenes procedure.

The major target of this approach is performance improvement when looking for the highest prime number less than 10.000.000 with a given sum of decimal digits. The problem requires implementation of sieve of Eratosthenes

First - Fedora 35 Beta Server deployed as L1 KVM Guest on F34 Bare metal Server . Nested virtualization enabled via virsh console on F34 Server. Complete KVM && Cockpit install performed on L1 F35 Server Guest per https://computingforgeeks.com/how-to-install-kvm-on-fedora/

Back in the year 1993, Linus Torvalds walked into a bar. He saw a lonesome cowboy about to mercilessly dig into a bowl of kernels. The cowboy said:Mmmmm, those kernels are the best… And that’s how a new operating system was born. Not with 10,239 lines of code, but with a kernel. True story!

First I've installed the most recent nightly build of Fedora 35 Server on Fedora 34 Bare metal KVM Virthost as Guest OS with "Fedora Workstation" desktop, like virtual machine seating on the Linux bridge been created via Web Cockpit Console. When done issued the following set of commands on F35 Guest

The problem itself is to find all solutions of the following equation on the real axis - cos (cos (cos (cos (x)))) - sin (sin (sin (sin (x)))) = 0. We intend to prove that equation above doesn't have any solution via creating a python script importing NumPy and Matplotlib.

I am posting this Howto due to currently available instructions on the Internet don't focus the user's attention on installation packages "ovmf" and "virt-viewer" on the most recent release Manjaro KDE. Skipping mentioned packages causes issues with Remote Viewer (Cockpit Console) and the ability to deploy KVM guests in UEFI mode
