I didnt know VB had a bare metal hypervisor... As for vmware, I heard the bare metal free license allows limited VM only...

I begin with xcp-ng from the beginning and have stuck with it since... works great depending whether you're using XOA or XCP-NG Centre as the hypervisor management tool

Oh yaya forgot hve only tried vb on vmware workstation

I tried esxi free version it seems enough for my use well i hope. But will give xcpng and proxmox a try later when i hve the chance

Seems like you had a great time with xcpng tho, kinda feel excited to try myself

Use free esxi and let the physical server running headless.

Run openmediavault 5 for NAS. You can expand its functionality by running docker container (transmission bt, plex, nms, web app whatever you want to try).

Run xpenology if you want to experience synology UI. Running xpenology in baremetal server require some degree of knowledge, run it from esxi is the easiest.

Anyone here familiar with Proxmox? I intend to use it as daily driver to load a Pop OS and a macOS concurrently. I'm trying to figure out what is the optimal storage setup needed for this to run, if I'm using a normal ATX motherboard.

Based on your requirement, better u run Unraid.
U can run jellyfin/plex for ur media streaming. torrent cliend also available.
search youtube for unraid. alot of example there.

u can ask me if u have question.

Now i'm running server with celeron j1800i, 8GB ram, 2TB parity disk and 1.5 TB data. Power usage about 15watt

Shit, this built is stealth as hell, is it holding up okay? I am planning something like that. As my old 4th gen i5 is drinking my tnb bill. haha. What have you hosted on your unraid?

I hosted mine with
Steam Library
Nextcloud
Bitwarden password manager
Steamcache 
Pihole Adblock
Reverse proxy
Dokuwiki
Duplicati
Jellyfin
Sonarr
Radarr

Do you do video steaming on them? if yes on what bitrate or res you playing? Transcode or without?

Because i saw new gen celeron can handle 4k pretty well but im still curious the ability of 15w TDP although with the help of Intel Quick Sync.

So basically here my case of use in general (as of now):
- for file sharing, media streaming etc.
- running and tinkering with different os

My plan is to run virtualbox with:
- freenas in VM (for storage management, media streaming)
- ubuntu (torrent, downloads, anonymity purposes n yadayada)
I dont quite get it with how to access the virtualbox actually. If i put the server in different room, am i able to remote access those VMs (freenas & ubuntu) with my pc or my laptop at living room? If yes, how the experience be like? I never try remote access before

I havent tried anything yet bcause i want to plan first how the server is going to be set up, and build it on 'solid' foundation.
Dont want to install much stuff if I happen to upgrade it in future.

Btw is virtualbox good for managing the VMs and having them remote access?
Not fond of windows or ubuntu server for the extra heavy resources and proprietary software.

So how's your journey of setting all those up? x)

But from your objective of being able to (storage management, media streams, torrent), you can basically done all these with any linux distro either in headless server or if you refer UI maybe just install ubuntu then add in other features like SMB + Nextcloud for storage management, Plex/Emby/Jellyfin For media streams and transmission-daemon for web torrenting.

Advantage of using VM is you can easily switch to use a different setup (OS, distro or application) if you're not satisfied with the previous setup. Moreover, there might be an existing OS image that can just reuse.

BTW, you don't use VirtualBox for remote access, for Linux you typically use ssh for command line. For GUI or other OSes, I don't know.

As of now, only running freenas as my file server cause it's what I feel I'd be using most of the time.

As for virtualisation, at first I thought of going with vmware but didn't feel like it. Doesn't feel like the way to go since esxi 7.x from what I read, is hardware compatibility nightmare. Plus docker is getting more mainstream. Still great for production though imo just not for hobbyists. Just for the compatibility issue that took it away for me.

Currently I'm learning kvm headless and oh boy, what a learning curve. Idk if able to go headless kvm. Gui centos might be the way to go if trying headless took too long for me.

i just trying to get into home server n see lots of tuto as much i can

but one part i dont get, what advantages of having multiple VMs on a server??

let say, i install virtualbox on my home server to run multiple OS's,

but how many ways i can access the installed OS's to make them usable? can i remote access and still have good exp? TQ

*I repost my thread here since /r/software seems no reply. I guess virtualbox or freenas being oss can be posted here hehe

1.) You use virtual machine as a sand box. With VM, you can easily reset your environment without formatting HDD.
2.) There are few ways to access the VMs remotely.
- Connect to the host machine remotely using remote access
- Use Virtual Machine client to open the virtual machine remotely
- If you are using Linux in your VM, just use SSH to connect to it.

Good exp is all depends on how much power you have, more RAM, more CPU, more bandwidth, better.

planning to migrate my setup on Mac mini to a more powerful Xeon server. Planning to use Proxmox to run macOS, windows, etc. like my current setup. Can share your experiences with setting up proxmox for your application?

Sorry my friend, but MCO ruined the chances of me getting the parts, will try again later this year (hopefully). But based on my research it is doable, the easiest path would be to find a compatible GPU for the macOS and also to have 2 GPUs, one each for the VMs that you intend to boot concurrently. Can have a look at nicksherlock.com for his Proxmox macOS Hackintosh.

no worries! I managed to get Big Sur 11.2 on my Proxmox 6.3-2. Hardware is a Supermicro mobo with a Xeon E5-2697v2. No external GPU/iGPU.
as long no crazy animation like launching Launchpad, it works just fine over NoMachine remote desktop biggrin.gif

This is really impressive, you only using it for work? I just can't seem to ditch Mac (cause the original is getting too expensive), so am aiming to get a Hackintosh and game on the side. The only drawback is this MCO and the lack of stock for the GPUs (their prices still too high for my liking). But no worries, slow and steady. More time to research. How would you rate the ease of using Proxmox on a scale of 10?

Ah, it’s actually to support all the network services (nginx proxy, web hosting, DNS sinkhole, caching, backup, thin-client environment, etc.) at home laugh.gif
I setup the macOS VM mainly for my home’s content cache server (for apple services, iOS updates, etc.), have around 13 apple devices at home laugh.gif

Yea, full spec ones are really exp where the same money can be used to build a pretty sick machine. This is my first time setting up hackintosh, lots of things to fix to get it to work properly.

Talking about the ease of use for Proxmox, I really couldn’t digest it at first, especially Proxmox way of handling disk/partition type/content, it took me 4 re-install of Proxmox to finally setup my disc partition correctly (single disk setup) laugh.gif after spending a day with it, I would say it’s easy to use and convenient, initial learning curve is very steep though (also due to the way I set it up, which all of the tutorials go for multi disk ZFS, etc.). Initially I would rate it at probably 3/10, after one day of tinkering with it, 8/10

Nice. So you're running Proxmox of one SSD? Are you passing through any HD for the macOS? Cause my research says, we can put in all on the same Proxmox install but baremetal speed is much better if we passthrough the HD for the OS that we need. I have only Hackintosh-ed a laptop before and that was crazy, need to make sure the laptop came with the right specs. But yeah, it was well worth it. A MacBook Pro-ish for RM3k with CD Drive. Hahaha!

Yea, one single Samsung 860 for Proxmox, window, macOS and Debian. pass thru SSD (baremetal) would be faster, but not sure whether have to pass thru an entire SSD to it or can share the same disk. My current server only costed me around rm2k, inclusive of shipping which was around 400+.
Better have another disk on the Proxmox machine as backup, very important. I just reinstall Proxmox yesterday night due to a dist-upgrade nuking my Docker on LXC setup, having back up the macOS VM was great, just restore back on fresh install

In a legacy environment with ten physical servers with different systems, you can save a lot of mony and get a more stable environment by virtualizing them and consolidatig to less hw.

If you build systems from scratch, i think containerization is more interesting echnology, but a lot still develop for an imaginary world with different full feature servers.
