Operating system made for VM

[ahmedhara]

So, I've just reinstalled windows since the boot time had gone from 2min 15sec to 4min since it really annoyed me. Linus was talking about his mainframe-like modern pc home idea where you've got a pc in the closet that can, preferably dynamically give processing power (or graphics power) to any device in the house and every operating system would actually be a virtual machine. I live in an apartment so I really don't need anything like that but it would be cool to have a base OS that boots in, eg. 20s and I can choose between a windows VM or a linux VM. And the difference between that and dual booting is that I can have multiple windows VM like, one for gaming, one for productivity, one for app development. You get what I mean.

So my question is:

Does there exist an operating system made explicitly for Virtual Machines?

As far as im aware, no.

And if im bluntly honest, its a great idea, but it wont work.

it'll take you longer, i'd just use windows multiple desktops.
Try splitting the drive into three, putting the programs into the 3, specifically. The boot drive being the only one thats loaded at the start.

If you really want fast boot times, i suggest getting a 8 gig or 12 gig USB stick and ready-booting it.

It sped up my computer from 2 minutes to 20 seconds. (aslong as its fast and usb-3)

This should do aslong as you have atleast usb -2.

It sped me up, and my computer has alot of rubbish on it.

Yes. What you're looking for is usually called a "type 1 hypervisor" or "Bare-metal hypervisor", though they can't dynamically allocate graphics power on-demand, at least not to my knowledge. Though you could assign a dedicated graphics card only for one VM, as long as you have a different one for the host system.

windows powered can but you have to script it in yourself so not for majority to use

but if your up to it see directx full power capabilities

Wow, sorry, I wrote the question badly, what I meant was to ask if there was a bare-bones operating system that could just run a couple VMs

look into windows nano server OS

That's exactly what a type 1 hypervisor is.

 

Here's one: https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2016

I guess putting KVM on a Linux server box is pretty close, too. They typically don't have any nonsense running in the background and can concentrate on the VMs.

tiny and yet handy

KVM should do the job. Also maybe look at a nas or use your host as fileserver to make life easier when accessing files on your vm's.

Level1Tech has some video's on how to do gpu-passthrough in kvm iirc

Maybe you should look at XenServer. I think its able to share graphics cards, and is a type 1.

Its also free, unlike many others. https://support.citrix.com/article/CTX135811
