Virtualization Explained | Docker | VMware | QEMU | Virtualbox

In this video, I am going over everything about Virtualization. I'm going over Docker, Open Shift, VMWare, HyperV, QEMU, Virtualbox, virt-manager with all of them Explained. You will have a good concept of how they all fit into the world of technology.

Hypervisors

Type 1
Bare Metal - ESXi, XenServer, and HyperV
Check old video

Type 2
Runs on top of Host OS - VMWare Workstation, VirtualBox, Boxes, QEMU/virt-manager, and unRaid

VMWare Workstation - Best out of the box and just works - limited functionality in free version

Virtualbox - Great out of the box settings and easy setup.

Boxes - Exclusive to the GNOME Desktop Environment - Clean setup - Limited Functionality on front end. Based on QEMU

Virt-manager - The defacto standard for QEMU frontends. Has a bit of everything and my go to frontend for QEMU.

The Rest
unRAID - This is like a weird hybrid that is like a mix of Type 1 and Type 2. You are able to make a single box, create two workstations. Its just odd, but awesome at the same time.

Containers
Docker and OpenShift/Kubernetes

Others exist but these two are really what everyone uses. .

Note: about 700 physical servers were required in London Olimpic Games 2012. After servers virtualization, technology, just about 250 servers were required in Rio 2016, Brazil!

This is a great video! I use virtual machines all the time, but did know only a little what is all behind it.

Great video, mate. Extremely informative

One relevant point: with SR-IOV you could use the same graphics card for both the host system and the virtualized system. Unfortunately so far both Nvidia and AMD don't support it on their gaming cards. AMD does support it for their more expensive cards. SR-IOV is the ideal solution if you want to run Windows-sooftware which needs graphics without leaving Linux so let's ask AMD and Nvidia to support it.

One easy way to differentiate between containers and VMS is:
VMs are hardware virtualization.
Containers are software virtualization.

really good introduction and clarification of virtualization, levels, types, differences, and uses of this software.
I commend you on the organization streamlining of this subject, too!

Hey. Seriously. Thank you. I just downloaded soft and I can CLEARLY see why your vid was recomnded. You're an aweso intro into

[linux_japan-infoby]

Very helpful! Thanks. I am currently learning about virtual environments.

[Dayta]

never mind my question on your other video about virtual machines :D gonna check this one .. looks like i have some catching up to do when it comes to your channel

[gaston-alegre-stotzer]

Good video, well done! Next up... VDI! I'm gonna try oVirt or XCP-ng + UDS this weekend... fun times... fuuuun times.

Great video! I would like to see more Docker video/tutorials in linux from you Chris. You just explain things so nicely.

[mitchelvalentino]

This topic has been covered by numerous YouTubers. But they all suck compared to this video. Awesome, useful content, Chris! Thank you!

Docker and Snap is like a better more advance version of Microsoft's Universal App Platform but for Linux. Its definitely the future. I use docker to run many LAMP containers for web app development, testing, and hosting.

[GiancarloCarccamo]

great video, you are a great person, thanks for all

[davidvantongerloo]

Hay, Chris, have a nice weekend Sir... nice video, many thing's i did't know thanks for the explaining this....

Unraid is incredibly useful for home NAS server purposes. Has Docker built into it. Not a replacement for another VM server... but it has it's uses.

[yruqqey]

I use a home setup with UnRaid for docker, Linux, and Windows VMs. It may not be as bare metal for gaming (though 3D is decent), but it's my main development host and NAS.

What about the Thin Client (popular ~ 1999-2005) or remote desktops (like linux X server running multiple sessions),
where do they fit in, for the current discussion?

[naveenbattula]

I used to use virtual box for everything but then docker happened. And the rest is history

[djohanson]

thanks for the pointers. trying to learn virtualbox but need to setup a machine first. I want Linux to host and windows guest. But idk, but this video helps with the terminology and what virtualization is .
