Loved your lectures teacher Nana .Can you please make a tutorial of any Machine learning algorithm probably a neural network which loads data of any type and using reinforcement learning gives results using python py charm.IT WILL BE A GAME CHANGER.THANKS TO YOU I LEARNED PYTHON FROM YOU AND LOVED DOING PROGRAMMING.:))

[@frankynakamoto2308]

Why not just make an operating system with both OS in them, windows and Linux and Obuntu and also all Algebra equations and encyclopedia all together.

[@kesariprasad2975]

@Nana : starting this vid with explaining type2 first and then moving on to type1 sure was the best way of teaching it. Doing it the other way might have created confusions. You are certainly helping many to learn concepts easily. Thanks a lot. Am a fan. 👍

[@tomboytomgirl5356]

@Nana: you are an excellent teacher. You know the subject fluently and you explain it SO CLEARLY! You created NO confusion in understanding the material. You are very good, Nana. Thank you so much and please keep teaching us.

[@getinthecar3624]

For someone who doesn't know anything except get on the internet. I learned from a video about 8 months ago about virtual machines. I finally just got it installed. (Finally getting to the point) This is by far the best teacher that I can understand how you explain things. Looking forward to more of your videos. Thank you so much

[@clintonugogeorge3416]

What I couldn’t grasp in 48hrs, Nana made it more clear to me in 15mins. Thank You 🙏

[@jacquibruce-yokoyama2478]

I appreciate the clear and concise way you deliver the technology concepts. No holding back, you explain certain quirks that may be confusing, in just a matter-of-fact simple dialogue. Thank You for Sharing your Expertise!

[@kirstenward4925]

I'm in the healthcare field. Computer software, electronics, whatever you call it is SOOOO foreign to me. Nana, has the absolutely BEST way of explaining this stuff in a way that truly appreciated and easily understood.

[@vladislavkaras491]

Great explanation! Especially, when you explained the practical use.

[@cristianeste12]

[@walkerwhippet]

[@user-go1rh8bi3x]

I liked the video very much and in the end of it, got the feeling that it was very helpful in my understanding of the concepts of VM. Thanks! I subscribed to your channel :)

[@insoYT]

It should be also mentioned that why virtualization is so much more powerful than bare metal servers is because it allows over allocating resources for VMs running on the same hypervisor host. You could have 4-core CPU on the hypervisor and you would be able to allocate these 4 cores to 10 different VMs and all of those VMs would have 4 cores available. It's a whole different topic how you plan such systems, but definitely one of the main reasons for virtualization as well. Usually up to 5:1 over allocation performance difference is imperceptible and cheap hosting services will go crazy with over allocation ratios to keep hardware costs to bare minimum.

[@flexairz]

You apparently never heard that overcommitting CPU's kills performance really fast...

[@ajeetmishra816]

really good explanation of virtual machines and hypervisor ❤❤

[@palanisamy-dl9qe]

Hi Nana, Thanks for your effort. I have one question here, As you said when I'm running my Jenkins instance (in AWS cloud)with Virtualization, just Assume it today Jenkins is not running reason is I made some changes in Jenkins configuration files, now the question is if I need to take backup of VMI as a snapshot but while taking snapshot I have Jenkins data with old configuration state file, after taking backup if I'm creating another VM with an image of backup data then again my Jenkins won't run right, in a new machine?

[@mohanvoleti]

Awesome 👍

[@ABDULKARIMHOMAIDI]

THANK YOUUUU

[@technologisthandle]

Very interesting video

thanks

[@haitamsteankir9358]

thank u

[@manoharmeka999]

That boot camp on Mac...is it the Type-1 hyper visor? If not, how we can get an ARM machine to install type-1 hyper visor and install different OS as portable files? But, if a computer hardware, the network card, can support only upto 65,000 ports, how come getting it 256GB RAM machine with 30 virtual machines of 8 GB RAM each can share those ports?

[@elnaraalakbarova2715]

Great videos Nana. Thank you. Where can I get information about 6 month Devops bootcamp?

[@elnaraalakbarova2715]

Nevermind, found it :)

[@socomax223]

awesome vid! i have an interview soon ! hope this is enough!

[@socomax223]

Update: I got the job as an os MS level 2 support engineer for VMs 👀
