Openstack is cool... I may get to it at some point... The main idea with Openstack is that you can spin up and manage servers programically vs. manually.
Hey Eli, your video's are great thanks so much for placing this stuff on youtube. It is a great teaching tool also. So many times people go into details without explaining the point. Even your intro on Linux, you don't sugar coat things great job.
One serious disadvantage I've seen to virtualizing servers is that applications with very sensitive timing requirements can fail. I was responsible for RADIUS servers which incorporated a watchdog thread that alerts you if it fails to run after more than a second. Clients typically time out if the server does not respond within 5-10 seconds. Since the system adminstrators moved these servers from physical hardware to virtual ESXi instances, I saw these "system lag detected" warnings frequently, usually between 2-8 seconds but sometimes going higher than 80 seconds.
Eli thanks man :) Gonna convert my i7 laptop to a bare metal ESXi hypervisor. got a 500gb SSD with 1tb storage. no more DigitalOcean or other services. Paying enough for my 300mbit connection already, gonna use that to host my websites and hobby projects. Your a cool man guy man :) love your setup, style. Keep it up. Peace!
this is the only kind of training that works for me. You really beat it into my dead brain. I appreciate your technique. Now I need to learn VDI in a box. I was hoping you would demonstrate citrix.
depends on what you're trying to do... Linux can't run an Exchange Server, or a Share Point Server or Active Directory... Linux is a great OS and I use it for a lot of things, but it's much less important in production environments then many people think.
You've long since moved past this video, but I wanted you to know that I'm just getting into IT and I really appreciate this video. I've been looking into putting a bare metal hypervisor on an old laptop I have sitting around for lab purposes and was wondering if VMWare is still the way to go for free options.
Further middleware like ERP, CRM, BI, BPM (OpenERP/Bravo, SugarCRM, Pentaho, ProcessMaker) are also available under both FLOSS and other parties services.
ELI am a big fan. now that said, I love how many ignorant people write comments here. right... Linux dominates the real world in server". I would like to see yet any company, other than in a datacenter or some other exception, where its user log into Linux instead of windows. Can you imagine the average employee learning Linux to be able to work LOL. P.S. I'm a Electrical-Computer Engineer and IT aficionado, I've learned a lot with your videos, surely the best in YT Keep it up :P
Good piece of info delivered within a very short instant of time ..... really appreciable , few things if included could make this more shinning(details about hardware allocation/resources utilization, )....:) better than reading the theories i always love to learn in a practical manner, thanks mate you are my teacher
Minimum requirements would be essential when thinking using type 1. Like for instance minimum ram (or better ram+ram speed), Minimum CPU/cores and bits (like if the hardware does not support 64bit, just forget it! or ... bla bla you can use in case of an non 64bit computer bla bla V. software). And all that of course dependent on the OSs you want to host e.g. if you want to host only Ubuntu (fe website hosting) you need bla bla GHz/Ram per host or if you want to host windows bla bla server you would need a minimum of that amount of computing power and memory. I think that would be helpful as a kick start for whether it is worth using V software based on current hardware owned or when considering buying new hardware to meet the minimum standard based on these indicators! However great job, I enjoyed very much watching this introduction to type 1 (btw I was wondering if the 348 number on the ceiling (@9:30) had anything to do with the Episode number 328?! hehehe ...)
Hello Eli, Its a nice video.thanks for sharing.How will I install OS to the hyperviser. Is that after installing the hyperviser to the main server and then install the OS by inserting CD to the server like what we do in our pcs ?
very nice and detailed video. I had a question. Can the hw resources be divided amongst different guest oses... ? For ex:) if my system has 4gb ram and i m going with 3 guest oses, can i allocate 2gb for a guest and 1 each for 2 other guest oses.. similary, allocate n number of nics per guest os, % cpu bandwidth... etc....
Assuming the Type1 server has the proper hardware, is it possible to set up a gaming VM that has decent performance over a high-speed local network? Example setup up a gaming VM for kids to use in their room on their laptops?
Great video! I am thinking of starting a pet project regarding the information you provided here about virtualization. I am particularly interested with a type-1 hypervisor. I have an Intel DQ45CB board with 4GB of DRAM (upgradable to 16GB), Intel Core 2 Quad Q9300 processor with 6M cache, 2.5GHz, 1333 FSB and an NVidia Quadro 400 video card with 512MB DDR3. Could you point out good references to help me get started? Thanks.
Eli the Computer Guy So this was the ESXi version which is not completely free What are the other free versions of Xen and does the original open source Xen have those nice options?
Linux can run an email server, a groupware server and a directory server. Yes it cant run microsoft software, but the actual functionality can be run. Every open or closed big company has this stack. Sun (now oracle) used to have: - Directory servers: Oracle Directory Server Enterprise Edition, Novel eDirectory or IBM Tivoli - Groupware: Oracle Weblogic, Novel Groupwise, IBM Notes - Email: Oracle communication messaging server, IBM CommServ and OSS: sendmail, zimbra, exim, kolab, LDAP
You can run esxi on the physical servers hdd's for enterprise use you just need a backup server you then install a free copy of the mangement software on there and you can backup the vms backbone files and then in a hardware fail you can reupload them and then reimport them as vms in esxi :)
I have a question if anyone is answering. When you set up the server instances on the hypervisor using the vsphere client, you want regular clients to connect to them. How does that work? Do they type in the IP address of the server instance (like Ubuntu or Win7) and connect to that directly or do they use remote connect? What I mean is that I don't think clients (other than the administrator using the management PC) should be able to create or delete virtual machines but rather just connect and use it. I might have missed this part and would appreciate if someone answered. Thanks for the videos.
They can Remote Desktop into a virtual OS that is installed onto a bare metal hypervisor if you would like the user to use the Virtual OS like any other OS. in this video he was describing multiple Server OS (not desktop OS) installed onto a hypervisor.

can u tell me how to connect the typ1hypsr server to citrix server ,can i connect it with lan ? and plz help me in understanding this u r installing ubuntu on hyperserver where do u insert ur cd(linux) wheather in citrix machine(mac destop) or in hyperserver (laptop).
my biggest question is if an individual sets up each server with a certain amount of ram that will over populate the ram when all servers over running at max, what will happen? Will the hyper v system crash? Will the SAN crash? Same with over using storage?
In my experience, performance of the hosted virtual machines will suffer as the hypervisor has to swap them around, much like applications will swap in and out of memory when they allocate more virtual memory than you have physical memory available. Storage space is handled differently -- you can't allocate more space collectively to your virtual machines than you physically have. The usual strategy is to leave plenty of unallocated space so that you can grow your virtual machines' storage when needed.
so can you install esxi on any machine? I was just reading that processor needs to be capable of virtualization technology and apparently my processor is not. I got Intel Core 2 Quad Q8200
There are open-souce replacements for those expensive Microsoft products Like SAMBA4 is functional in Active directory, even as a DC. OpenChange, is a very promising drop in replacement for Exchange, even works with Outlook. There are several Sharepoint like Linux projects out there too. It all depends on the budget you have for IT. In my field, we use a lot of, Microsoft, simply because if something goes terribly wrong, we can sue them.
Great video, but I can't help mention that Xen is not the father of type 1 hypervisors. Xen was first introduced October 2, 2003 (see Wikipedia). ESXi grew out of ESX, which grew out of GSX, which was first introduced in 2001. VMWare Workstation's origins reach even futher back: 1999.
most people would look at this question as stupid but many Server boards including intel have Eusb SSD for that. because once booted Vmware ESXi runs in ram.
Paul09 Offered no proof well, i am currently going through Windows Server to Linux Conversion as linux uses less from a resource pool example Windows 2008 Server idle 230Mhz Mail Active Directory/ web server ect, Linux Server 10Mhz idle, The workstations that use this are WINDOWS 7...... So yes you can. Share point Never used it i dont see the need if you setup your network and vpn right.....also my server is Vmware esxi 5.0
Nope... In a real professional world everyone uses Windows. Linux is reserved for task specific production systems. Outside of Web servers and cloud systems Windows Servers dominate the Enterprise and business environment.
Windows may dominate the desktop (though Mac OS is a strong competitor in certain industries,) but I highly doubt that Windows dominates the server market. The figures depend on who you ask, but a survey conducted in 2014 reported that Linux' share of servers grew from 65% in 2011 to 79%. At my previous company, they only use Windows servers for internal business services while Linux is used for all of their engineering and external-facing servers.
well yeah if you're going to be doing some desktop application but linux dominates the server industry everything windows can do linux can do 20x better with the exclusion of desktop experience
Sincerely, This is the Best tutorial i have even watched on RUclips. Eli you are too good.I learnt quite a lot from you.
Clear and simple. This is my first introduction to Virtualization. Thank you so much for breaking it down!
Was looking for the concepts to be cleared..n got the right guy explaining each and everything .. Great Work Eli... and really Thanks a ton man !
Openstack is cool... I may get to it at some point... The main idea with Openstack is that you can spin up and manage servers programically vs. manually.
Very Comprehensive way of teaching, i have been looking out for this method since very long time and finally can say i am in safe hands now. !!!
Hey Eli, your video's are great thanks so much for placing this stuff on youtube. It is a great teaching tool also. So many times people go into details without explaining the point. Even your intro on Linux, you don't sugar coat things great job.
.... I'd like to see some numbers to back that up...
Wow..This is brilliantly explained..This is what I was looking for...Thank you bro.

Big thanks and big ups to you Sir. Another fascinating addition to your repertoire.
Your videos are absolutely awesome, so helpful. As an IT guy, I can't thank you enough. Thank you, Eli! :-)
This subject is very interesting, I hope he continues with this type of videos.
Only one minute passed and dog already has my attention
Simple ans awesome way of teaching. Thank you and much appreciated.
depends on what you're trying to do... Linux can't run an Exchange Server, or a Share Point Server or Active Directory... Linux is a great OS and I use it for a lot of things, but it's much less important in production environments then many people think.
Learn how to install type 2 hypervisor (Virtualization) practically from the following link: ruclips.net/video/FCUf8yxHy9A/видео.html
You've long since moved past this video, but I wanted you to know that I'm just getting into IT and I really appreciate this video. I've been looking into putting a bare metal hypervisor on an old laptop I have sitting around for lab purposes and was wondering if VMWare is still the way to go for free options.
Virtualbox is definitely the way to go for free options.
Further middleware like ERP, CRM, BI, BPM (OpenERP/Bravo, SugarCRM, Pentaho, ProcessMaker) are also available under both FLOSS and other parties services.
Very easy to listen to. Thank you
Cool, 10 years old but still meaningful today as it was then. 👍
I was very comfused about what bare metal servers, thanks, really clear.
Hi Eli please explain still more on hyper and the set up of the OS instances
ELI am a big fan. now that said, I love how many ignorant people write comments here. right... Linux dominates the real world in server". I would like to see yet any company, other than in a datacenter or some other exception, where its user log into Linux instead of windows.

Clear illustration! Thank you!
Excellent video!
9:40 *This laptop is what houses my servers.*
Is it possible to manage the hypervisor from this same laptop? Or you must have another machine???

What are your thoughts on running ESXi on a thumb drive in production?
Hello Eli,
Its a nice video.thanks for sharing.How will I install OS to the hyperviser. Is that after installing the hyperviser to the main server and then install the OS by inserting CD to the server like what we do in our pcs ?
very informative , what about OpenStack , it would be appreciated if you make an episode about OpenStack
very nice and detailed video. I had a question. Can the hw resources be divided amongst different guest oses... ? For ex:) if my system has 4gb ram and i m going with 3 guest oses, can i allocate 2gb for a guest and 1 each for 2 other guest oses.. similary, allocate n number of nics per guest os, % cpu bandwidth... etc....
Just awesome! Thank you.
my right ear enjoyed this
YES i was just about to ask you to do such a tutorial!
Great video, very useful. Thanks Eli.
Assuming the Type1 server has the proper hardware, is it possible to set up a gaming VM that has decent performance over a high-speed local network? Example setup up a gaming VM for kids to use in their room on their laptops?
Very good tutorial. I want to know if there's something similar to this but including the administrator software in the same machine.
so let me get this straight.. a type 1 hypervisor is like installing VirtualBox directly on the physical computer without Windows?
Essentially yes.
Although that is not possible with VirtualBox in particular
Great video! I am thinking of starting a pet project regarding the information you provided here about virtualization. I am particularly interested with a type-1 hypervisor. I have an Intel DQ45CB board with 4GB of DRAM (upgradable to 16GB), Intel Core 2 Quad Q9300 processor with 6M cache, 2.5GHz, 1333 FSB and an NVidia Quadro 400 video card with 512MB DDR3. Could you point out good references to help me get started? Thanks.
So where a Type 2 hypervisor runs one OS inside another, a Type 1 hypervisor runs different OS's beside each other, independently?
Eli the Computer Guy So this was the ESXi version which is not completely free
What are the other free versions of Xen and does the original open source Xen have those nice options?
Is it possible to assign multiple server (multiple laptops/ towers) to one operating system so the one operating system uses the whole Ressources
Have enough monitors? Jk lol great video. Learned ALOT! Your one of the best !
Thank you, it is really useful
Great episode Eli!
Recommended hardware to get?
so is VMware's ESXi a bare metal hypervisor?
O KK yes
Whit can I get a normal os on a type 1 hypervisor? Or did you just say server because that is probably the most practical use for it?
This is great stuff. Thanks
thank eli.. this video cleared my doubts ,,
Is there an open source Management software?
How do you get one mouse and one keyboard connected to, two computer screen?. So, like the mouse can go from one screen to the other?
Eli, Please can you make a video explaining how to install Ctrix Hypervisor ? Thanks

how come I haven't heard of it till now?
Great Vid! Tnx!
can i cluster these servers together using psi to pci cables lol. or sata cables. thunderbolt is pretty fast too.
thanks Eli
Those monitors look loveeeeeeeeeeeeeeeeeeeeeeeeeely.

12:42 I DON'T WANT NORTON ON MY GOD DAMM SERVER, lol
it can run an active directory because i have done it before
does this work on a Mac? I really like messing with my school pc.
Epic man cave!

Tnks sir,Thank you for this video. how it's works with macOS.
no cd, but an image file unless you want to use the cd/dvd (optical disc)
I believe everything where I work is Windows, Office, Server and Equipment Computers. I don't know why but I have no say to change it.
Informative
Is VMware Certification worth it- do you get jobs if you have them ?
yes
Perfect
Thank you ..
ProxmoxVE - free open source hypervisor, with HA -web based management software - try it :D
good man
Thanks! I though this would be a lot more difficult to understand/implement.
most people would look at this question as stupid but many Server boards including intel have Eusb SSD for that. because once booted Vmware ESXi runs in ram.

Since it is 2012 here I'd like to warn you about an upcoming pandemic in 2020 onwards and how to avoid infection. P.S. It really SUX !!!
XCP is awesome and free.
Freenas and some other Nas Servers run off BSD and they are all over.
In the real world BSD is at least as, if not more widespread than Windows or Linux.
You mean "Please"
well yeah if you're going to be doing some desktop application but linux dominates the server industry everything windows can do linux can do 20x better with the exclusion of desktop experience
Of what? BSD? Are you baiting me?
Watching this video on a virtual machine....
