Finally a clear explanation. I am a "not an IT guy" who wants to learn more about IT and security. Creating analogies and presenting it interactively was very, very helpful. Look forward to more of your videos!
I am happy that you found the video informative. Next year I will produce a lot more video on virtualization, since now I have a new Intel Xeon machine built for running a lot of VMs.
Excellent visual explanation. I use virtualization such as Proxmox, Server2012 HyperV, and Virtualbox but never understood type 1 or type 2. Now I am more informed. Thank you.
I am glad that you found the video useful. In the following episodes I intend to go over the virtual switch, and the new VMD-q, VT-d and SR-IOV hardware extensions as well.
I am glad that it helped. Though, in order to be more informative I have made very rough simplifications, and not mentioned the protection rings where different code runs and how VT-x is exposing Ring 0 of a CPU to the VM by running the hypervisor in Ring -1. When I will have time, I will make some follow-ups on this content.
Thanks for the comment! As you see, not many people were interested in the basics of virtualization, this is why I was not making new videos in this series. Still, if there is interest, I will continue with the other topics as well.
Great , Great Explanation for Types of Hypervisopers. One of the best explenation i have watched on RUclips. Please keep going on and explain the : Assisted virtualization and the Paravirtualization. What about Vt-d and AMD MMU ? and a comparison between Hypervisor KVM , ESXI , XEN and Hyper-V
Thanks for giving your opinion on the video! This is part of a video series, where I will step-by-step go over VT-x, Virtual Switch, VMD-q, VT-q, VT-d and finally SR-IOV using the same type of presentation with hardware and cardboxes. Stay tuned for those ;)
For some reason a few comments from people do not appear on this video, and I cannot respond either. Sorry, it is not my fault! YT is broken as usual...
Wonderful!!! i just have one query to be clarified, in type 1 hypervisor though the hypervisor has direct contol over the memory management unit(MMU), does the OS's (installed above the hypervisor) also have direct control over the MMU? or it has to communicate regarding the allocation of memory through the hypervisor? pls answer the query!!!
I am glad you liked it! Hopefully in the future I will have more time to produce videos on how hypervisors run in the -1 protection ring using VT-x and AMD-V extensions.
@@DonkeyLearningIT I memorised this whole explanation. Actually it was not even memorisation, it was more indepth understanding. Hoooooowever, in my final exam they removed the questions. I was super prepared to give his explanation.
How do you feel after AMD released the Ryzen CPU ^_^ . They are simply amazing. However many people told me that intel CPUs are much better for Virtualization. Currently i have 2600k and i am planing to upgrade to AMD Ryzen7 1700X and i want to make sure that it's fully compatibe with KVM and Qemu and provide same level of performance like Intel provide.
To me it seems that the community have expected a LOT more from AMD Ryzen, and my personal opinion is the same. Namely, these CPUs are too expensive for what they deliver. As they say in English: too little, too late, too pricey. If AMD wants to get back into the race (it would be good for all of us buyers/companies/costumers) they would need to reduce (70-100Euros cheaper) the prices on their Ryzen and work on the server CPUs. Sadly for virtualization Intel almost have become a monopoly, since the AMD virtualization features are often purely supported by the hypervisors. Since now Intel also have developed omni-path, it will totally DOMINATE also the HPC market as well...
I rate this video: The Best Explanation for Hypervisors & virtualisation stuff ever! ! You have +1 subscriber. ✓

Yevalo periya concept 😃 rendu Box Ah vachu explain panitaya vera level.. God Level Teaching Sir☺.

Thank you very much!!! You have a talent to convert complex matters into very simple segments - So please continue to develop it.
Very good presentation and very good analogy used to explain hypervisors.
What a clear demo and explanation... Excellent explanation... ☑️☑️☑️☑️☑️👍👍👍
Seriously! haven't found any other content on net so sought out for such a complex topic
Thank you
Excellent Video.. I learnt a big concept with your simple demonstration. Really thank you for your time, effort, explanation and the video...
You done really awesome work for this video.. simply saying thanks is not enough for you, it's beyond
Excellent, this is the simplest way to understand all this...woow!!

Cheers for the great video mate. Really cleared up this concept for me :)
incredible , very good explanation , usually i don't subscribe , but this time i'll, keep going.
Great vid! A very clear and understandable analogy.
Great explanation!!!
Thanks for this video.
superbly explained. thanks a lot.
Beautifully explained!!!
Thanks for the comment!

I'm interested in you continuing with other topics as well, since you explain complex concepts quite well.
Thanks for easy explain
Awesome Video! Very simple explanation of type 1 and type 2 Hypervisor:>)
Great , Great Explanation for Types of Hypervisopers.
One of the best explenation i have watched on RUclips.
Please keep going on and explain the : Assisted virtualization and the Paravirtualization.
What about Vt-d and AMD MMU ?
and a comparison between Hypervisor KVM , ESXI , XEN and Hyper-V
Thanks for giving your opinion on the video!

Super Explanation Sir
this is just amazing! thanks for the video.
Thanks for the comment. When I will have time, I will probably make the continuation on this series regarding VMD-q, VT-d, SR-IOv as well.
Thank you very much. Well done,
Amazing Explanation!
Thanks for the comment. I hope that the video was informative.

Sorry, it is not my fault! YT is broken as usual...
Excellent explanation!!! Can you please make a video on para, full, hardware-assisted virtualization and their functions?
did you get the videos you requested
you are the pro!
excellent

@@natbett206Good on you if you have passed the exam!
What kind of exam was it btw? Some certification or related to technical school?

I think they provide very respectable performance comparing to their price.
But for Virtualization part i agree with you.
hai sir
Hi to you too!
