Why are many people talking about VM? Like I couldn't get if you're using it instead of dual booting or it's something else going on in the hind side.....

@iKameo but you don't have much control over hw isn't it?

@iKameo thanks .
Could you tell me a bit more pros of VMs?

@iKameo thanks

You can set up a complete virtual network with VMs if you have the RAM for it. The usecase is rather big for VMs actually. But more interesting for sysadmins then devs generally speaking.

@rootshell thanks

@VTCoder Well did you mean more VM or Virtualization in general?

vm:
1. sandbox for testing fishy software
2. running multiple OS at the same time
3. running a mouse macro in the background(yes I've done this 😂)
4. quicker then having to reboot for your dual/multi boot installs.
5. preconfiguring an install(granted works better with Linux)

Virtualization
1. sandbox for users
2. same environment for users
3. adding or removing functionality at a flick of a button
4. abstraction from hardware( there is now an concept of hardware made in software which is an interesting thing)
5. scale
6. speed
7. power consumption benefits

@rootshell thanks for telling me more and removing my confusion.... BTW could you explain more on sandbox for users part

@VTCoder Well the virtualization is basically used as an layer to abstract away the host OS and hardware.

Say you have an company of 500 people.
They all log in via citrix or xen or what have you and get the same VM exactly the same. They can't do anything to it other then what you want them to be able to do.
Physical hardware it's easier to circumvent.

What you'll see a lot is that people who have laptops from the company are often free to install what they want because they might not be at work.

If you use virtualization you can add that user to an specific group and it'll spin up a diffrent VM for him with his specific needs.

@rootshell wow. Thanks sir. BTW what do you do?

@VTCoder As in work?
I'm an sys admin student who likes to code in his spare time. I am technically first years but already did a similair but lower degree already.
Currently doing an (required) internship. Doing it internationally because looks better on CV.
Had to quit my kick ass job of being a pool guard though. 😥
Also if you hadn't noticed by my username I like Linux.

That should suffice as answer I believe. 🤐

@VTCoder also please don't call me sir. I just turned 23. You make me sound so old. I do respect that you talk to strangers with respect but nobody has to call me sir. 😁
