Class Notes
Introduction
Virtualization allows you to separate the Operating System from the underlying hardware
Virtualization is NOT the same as Cloud Computing. Virtualization is a Type of Cloud Computing.
Hypervisors are the software that Operating System "Instances" run on.
Overview
Virtualization allows you to easily migrate servers between pieces of physical hardware
Virtualization allows you to consolidate multiple cheap physical servers into one server
An "Instance" is a "Virtual Computer" installed on a Hypervisor.
Type 1 Hypervisors
Called Bare Metal Hypervisor
Installs directly on to hardware
You use Management Software installed on a different computer to manage a Type 1 Hypervisor box.
Based on XEN.
Generally the Hypervisor is free, but you pay for the Management software
Over Allocation allows you to allocate more total resources to the Instances of the operating systems then the physical server has. At any one time all Instances CANNOT use more resources then the total amout that the server has.
Type 2 Hypervisors
Called Hosted Hypervisor
Type 2 Hypervisors are installed onto an Operating System such as Windows 7, OSX or Linux. (VirtualBox, Virtual PC)
Be careful allocating resources to virtual machines. You have the ability to allocate so many resources to the virtual machines that you crash the host machine.
Networking can start acting "weird" on the host machine when Virtual Machines are running
Converting to Virtualization
Vendors of Virtualization software have "conversion" software that will convert an Operating System that installed on a Physical Computer into a Virtual Machine
Many pieces of Backup Software no backup servers directly into a Virtual Machine.
Final Thoughts...
Be careful of licensing!!! Per Server/ Per Socket/ Per Core
Virtualization software is stable, and not "cutting" or "bleeding" edge technology.
Resources
Xen
Citrix
VMWare
VirtualBox
Virtual PC

Best teacher on youtube! Not like these other guys that try to sound smart just to confuse people. Eli does it so we can truly understand thanks Eli

[@osasogieosazuwa6448]

Eli is just simply a great Guy. Such people make the world a better place!

[@zcarenow]

JayThrilla 200% I agree.. he is the best

[@juanchicchon5017]

Thank YOU! ELI!, regards from Lima, PERU.

[@ZFlyingVLover]

I don't understand how ANYONE can give this guy a thumbs down. He's the Khan academy of hardware and networking. Cheers

[@romchompa6858]

he spends a lot of time repeating himself, but i wouldnt say enough to downvote

[@khalidalkhuraiji1373]

The beauty of Eli is that his "ability to explain the technology and pass it to others in a very easy and understandable way" .

[@MrPaintmeblue]

You are, by far the best teacher I have ever come across anywhere, online or in person of any IT topic. Man you probably don't even realize how big a service you are doing to folks like us who scour through reams of documents and large contents on the internet just to get a grasp of these topics. THANK YOU!!!

[@karimkrimou2568]

Almost 10 years and this course still one of the best courses out there on virtualisation. You give me the will to switch to IT everytime I watch your videos. Your way to teach things is amazing. You seek like a very nice guy

[@TheRangeControl]

Eli, I will always be indebted to you. Almost anytime that I have a system question, there you are with an Army styled point by point block of instruction on the subject. Thank you for all of the digestible, yet comprehensive content.

[@anilyakthumba1606]

This is a only classroom, where I never fall asleep.....

[@chetanpawar0989]

Same here man.

[@itpugil]

+Anil Yakthumba same! :)

[@sathiarajsugunakumar]

200% agree...Eli is the best teacher

[@tomartygirl]

haha yesss I completely agree!

[@aalihte3378]

i watch other "guides" on KZbin and they are sooo monotonous. .i always come back to yours. thanks for all the googobs of useful info :)

[@helcioandrade]

He goes directly to the point. That´s why I watch his tutorials videos. And his English is easily understandable. Thanks for helping us all.

[@benjpress]

This is why i love youtube. Who said education can't be free. Thank you for the Tutorial! Subbed, Fav'ed and Liked.

[@rogerjonathantene8053]

Is your TV channel free, if you can reply you can understand that it is not really free man.

[@pagola]

watching a youtube video is not real education

[@sureshkhanal2473]

Eli, I have watched a few of your video classes. They are simply great and great and you really have done a superb job, man! I have benefited tremendously from each of your video. Please do keep posting more of those videos. Thank you so much for putting out a genuine work on KZbin. Suresh, Ontario, Canada.

[@aamirehsan2545]

the beautiful thing about eli is ---- bloody hell seems like he is reading my sleepy mind and he repeats and recap everything, which I pick up even if I have missed anything during his first intro ---- one of the best teacher I came across in my whole life

[@njw6146]

Huge Fan man,i remember having your "Introduction to networking video" that really got me more into starting my IT career! now I'm head of IT with knowledge in networking, Windows suit, Firewalls and getting into the cloud game and deploying OpenStack this month. Thanks a lot!

[@nekkowe]

Wonderful, thank you so much :0 Most presentations, even lectures in real life, have zero redundancy and just blast through the material at incomprehensible pace. With yours, it's like... listen to it, okay, got it in one, woah. I actually understand the concept instead of just learning to parrot the words to describe it.

[@dadgadfolkmusic200]

I truly enjoy Eli's lessons. He is great at explaining things in a simple way and he ties up information together beautifully, not to mention his indispensable repeat of vital information for the viewer to easily and quickly retain. His delivery is smooth and his manners are charming. Many thanks Eli!

[@prashantkumar2705]

[@AnthonyP2A]

Eli, I've been working in the IT/communications field for over 20 years and I have to give you a really big "thumbs-up" on this video. I've learned all about VM's and all the animals it contains. You explain things very clearly, and in a very good pace. Kudos to you, keep up the great work!!

[@SiddharthSinghFiery69]

Thank You so much Eli Sir. I am a fresher undergoing training in Cloud Computing in Capgemini. I always watch your videos before my assessments because you explain every topic crystal clear.

GREAT JOB bro!!!

This was an awesome video! I now feel like I have a mental framework to better learn the specifics of the many virtualization tools. Also, you are a natural teacher, and I really appreciate your starting with the big picture-- IMO this is critical, but often overlooked in tech training. Thanks so much for posting this!

[@diedforurwins]

Dude I have tried so many courses you are straight up the best teacher I’ve encountered

[@ravikumarck10]

Great Eli. U r one of the very few who has technical know-how, and the ability to articulate in simple words.

[@lIstRduN]

This is a great video to learn the very basics of virtualization. I've been looking for something like this for weeks, everything seems to skip over the basics. I can now say I actually understand what a hypervisor is, before it was just a word I've heard many many times. It's a shame you're not the VMware CBTnuggets guy, you would rock!

[@bryanarmstrong5747]

Very well explained! Even though I knew some of the things that Eli covered about virtualization from reading VMware white papers, Eli helped me fully understand what I read in a very understandable and relatable way! Thanks!!!

[@Abianco73]

This was a great video! I've been trying to use wikipedia to figure out this concept. Your explanation was much clearer to understand. Thanks

[@DareBear2099]

Best presentation on visualization that I have found on KZbin.
