@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. 👍

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

@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.

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

Why people can play the dislike button to Nana's videos? What is wrong with that people?

[kirstenward]

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.

[devorein]

Really great tutorial. Extremely well explained. Thank you.

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.

[prashantganji]

Crystal clear, now I know what is VMware ESXi, Hyper V, Snapshots and more, Thank you so much Nana!

[fahimmuhammadkhan]

It was really very informative.. U have created the internal confidence of us to debate on OS concepts. Thank You

[thomash.]

Another perfect explanation Nana, thanks!

[vladislavkaras]

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