Cockpit-Machine is an open source virtualization add-on to Cockpit for Linux. RedHat deprecated virt-manager in RHEL 8, however the project is still alive and well according to many Linux sources, however it has not seen any activity since the 4.10 release over a year ago. I moved to virt-manager when I could not get enough performance out of Oracle's Virtualbox. The GUI to virt-manager is a bit dated, and is in sad need of an overall. I decided to check out what Cockpit-Machines had to offer and this video is my first experience playing around with it and using it.
The short answer to the question is, "I do not know" - I never do when first starting to use something, it takes time to get to know the ins and outs of the software, where its strengths are and where it falls down on the job. The lines have blurred between a typical Type 1 or Type 2 hypervisor today, but this one is clearly a type 2., just like virt-manager. Cockpit-Machines like its predecessor uses the same KVM/QEMU core that virt-manager used. Both are a step up from the complex configuration of KVM and QEMU.
One last thing /etc/libvirt/qemu.conf holds the configuration for both vnc and spice, you will see both default to localhost only, but you can change it here and it will allow your VMs to work over the network. One word of caution, if you are wanting to use vnc or spice over an open network (Internet), you will need to setup TLS and X.509 certificates to protect your session and your VMs while accessing them.
You can find out more about setting up TLS and X.509 certs here: https://cockpit-project.org/guide/latest/

This more than a sponsored video, I wanted to talk about the kind of projects you can make with this kit, how to get more information about using these computers, why it matters and where you can go to get additional help when you need it. There are local user groups in my area which meet weekly as well, check your local area for groups like these.

Storage Solutions Past, Present and Future. Unraveling the Alphabet Soup of Acronyms
In this video I look into how storage solutions have evolved from SLED to RAID and providing file sharing services using NFS and Samba (or SMB). The hardware I am using is an ARM based Odroid H2 and Odroid H1 running Ubuntu Server for ARM

In this episode of the CyberGizmo we explore SysCalls and how they work in Linux. I will also discuss the differences between monolithic, microkernels and nano kernels in this video.
The Linux Kernel Archives Documentation: https://www.kernel.org/doc/html/latest/
Oh and one more thing, each line in the strace is a linux command or call, you can use man pages to lookup what each of those do.

Buying a new CPU, Motherboard? I could just do a video on what is Amdahl's Law, but with all the new CPUs coming out with more cores, more threads and higher CPU Frequencies. It's time to take a page from Enterprise Computing, because "Toto, we aren't in Kansas anymore". The rules you learned back in the quad core days are out the window now. And you need to understand how to predict and measure performance to get the most out of these new CPUs. Sadly, I do not have a Windows machine to show you but you can run GeekBench on it to get the measurement you need
Serial processing means strictly sequential, without overlap of the successive processing times on objects or distinct subsystems. In a standard type of serial system, each object takes the same average amount of time to process and the next object begins processing only when the previous one is completed.
Parallel processing signifies simultaneous processing on several objects or subsystems at the same time, however processing may finish on different objects at different times.
BTW, Neural networks do not predict well using Amdahl's Law either, as cores are added to a neural net, the system will grab more data, similar to the HPC problem Gustafson points out.
