Recently I was about to change my Home lab. I wasn’t changed since 2013. I works stable, everything what were able to virtualize were virtualized. Things like my CCTV, webmail, NAS are running on dedicated separate server. Another dedicated server is my firewall, sorry, but security is vital priority. But my third server is virtualization station for tasks like web servers, remote sandboxes, development environments and various sets of VPN channels. Everything run quite smoothly on Windows Server 2012 R2 under Hyper-V. The 16 GB ram with 8 cores and several SSD and HDD drive are enough to separate all the tasks.
So why I decided to make some changes if everything is up and running ?
- Windows Server 2019 here. Means EOL of Server 2012 R2 is the matter of time.
- Too many adired screaming around KVM, ESXi and XEN
- I had huge experience with ESXi versions 3.3 till 5
- I wish to make hardware upgrade for this virtualization system and this is perfect opportunity to try something new
- KVM, ESXi and XEN are free (the Windows Server 2012 R2 was obtained almost for free £400 with outdated dell server on Ebay). Means after EOL Windows Server 2012 R2 I’ll have to pay to Microsoft crazy price.
Early Saturday in the morning I found that my total night backup was completed and I’ve started my efforts to test and implement following solutions: Continue reading

Here is the story about Black Arrow fraud company where I’m unfortunately the main participant.
As an ordinary IT guy I decided to try myself in the world of cryptocurency minining. In August 2013 I’ve bought a huge ATX motherboard with 4 PCI-e slots and expensive AMD video cards. The choice of concurrency for mining was BitCoin. I’ve registered with 50BTC pool and mined something about 1.2 coins until the 50BTC pool was hacked. Later on I’ve dropped all the video cards (somebody received a perfect present) and decided to buy a specific mining equipment for BTC.
During October 2013 I was browsing around the mining forums, trying to understand what is scam and what is real in the concurrency world. Majority suggestions on the market were absolute fraud websites which suggested various ideas to bump your pocket and to fool you in polite manner. So I’ve made up my mind and in December 2013 I’ve ordered Bitcoin miner from Black Arrow fraud company, a model Prospero X-3 for $6000 USD.
While you are reading this, I hope you are not one of these customers like me, who did the same order from Black Arrow fraud company, so I will not ruine your mood for the rest of the day.
The world is changing rapidly. I’m glad to announce that more and more alternative CPU appeared today. Since the leadership now belong to US companies like Intel and AMD, and British ARM, there is another release of newest Russian CPU – “Elbrus-4C”. It’s predecessor “Elbrus 2C+” was good enough for almost any real world needs, but this new “Elbrus-4C” is almost equal to modern desktop and server CPU the market leaders.
Everyone who ever used MySQL under heavy load faced the performance problem. There numerous manuals and advises, tricks and “how to ?” examples. But you will definitely not find the solution which suits 100% for your project and will fix all your issues. You have to learn it. You have to spend your time.
