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.

Install Win11 as Virtualbox 7 Guest on Ubuntu 22.04 and SparkyLinux 7
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 .
Install Win11 KVM Guest on SrarkyLinux 7 via conversion virtio-win-0.1.229.noarch.rpm to format *.deb
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 .
Install Windows 11 as KVM Guest in SparkyLinux 7 using virt-manager
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 . . . . . .
Set up KVM && Cockpit WEB Console on Debian BookWarm (12)
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.
Install Windows 11 as KVM Guest in Fedora 38 WKS using virt-manager
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.
Install Virtual Box 7 on Fedora 37 Server via rpmfusion repository
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.
Verification CLT via flask && matplotlib
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.
Uploading dictionaries into SQLite tables via Pandas DataFrames on Python
The following below is a not entirely trivial algorithm for students that creates a Python dictionary after scanning text according to the conditions of the problem, which gets converted into Pandas Dataframe and uploaded to SQLite database table to be analyzed via nested SQL Query.
Exersing Python 3.10 on Fedora 25 via sorting Pandas DataFrame
The following below is a not entirely trivial algorithm for students that creates a Python dictionary when scanning text according to the conditions of the problem, which is then processed as Pandas Dataframe to provide the output required
Python Wrapper to find all primes from a given interval via sieve of Eratosthenes released in C++
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
Python Wrapper for sieve of eratosthenes released as C++ procedure (YandexQ question)
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.
Solution another YandexQ question via sieve of eratosthenes in Python
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
Attempt to test Web Cockpit Console on Fedora 35 Beta Server (VENV)
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/
111+ Linux Statistics and Facts – Linux Rocks!
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!
Set up Virtual Box on top of Server F35 (pre release) via rpmfusion (VENV)
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
Python (numpy && matplotlib) solving one relatively difficult math problem
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.
Deployment KVM Guests via Cockpit Console on Manjaro KDE 21.1.2
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
Set up KVM && Cockpit WEB Console on Debian Bullseye (11)
The presence of Web Cockpit Console is a nice way to manage KVM guest's deployment via clicking the button "Remote Virt-viewer" built into Cockpit Web Console. Bridge attached to external network interface was also created pretty smoothly utilizing network management section inside Web Console. However, it doesn't look to me as a reason to deprecate virt-manager .
Set up KVM && Cockpit WEB Console on Ubuntu DDE 21.04
First notice that we intend set up Ubuntu DDE on Ryzen 7 3700 box with board MSI X570 A-PRO in UEFI mode with "kvm" enabled. Enable SVM in the BIOS Setup due to it is disabled by default. This step might be the hardest to complete in the whole installation procedure.
