Ultimate Guide to Virtualization: Run MacOS, Linux, and Windows all at once on the same machine!
Dave explores virtualization and hypervisors, including both Type 1 (Proxmox, Hyper-V) and Type 2 (Virtual PC, VirtualBox), For info on my book on ASD/Asperger’s, please check out: https://amzn.to/47ItFnR
00:00 🖥 Virtualization allows one piece of hardware to host multiple operating systems simultaneously, managed by a hypervisor.
02:51 🛠 There are two main types of hypervisors: Type 1 (directly manages hardware) and Type 2 (works through a host operating system).
03:48 🏠 Hypervisors keep virtual machines isolated, like different people sharing a house with their own space and resources.
04:15 💻 Hardware virtualization requires CPU support, and Type 1 software hypervisors can have minimal overhead (as low as 1%).
07:55 🧠 Proxmox is a type 1 hypervisor based on Linux, capable of hosting multiple OS installations.
09:17🖥 Virtual machines can be configured with specific CPU cores, memory allocations, and disk space limits in Proxmox.
12:48 🔄 Nested virtualization (running a hypervisor within a hypervisor) is possible for testing purposes but not typically used in production.
13:46 🧬 Virtual machines can be backed up and restored easily for disaster recovery, providing a high level of protection.
18:40 🪐 WSL 2 integrates Linux into Windows using a lightweight VM with minimal overhead for seamless interoperability between the two systems.

Is it possible to passthrough Network (WLAN or Ethernet) card to HyperV VM with Linux and running some kind of proxy server there to prevent Windows from spying on the user? Currently I'm doing this with Vmware Workstation, but it requires external USB network cards to pass to the VM, which is not fully convenient.
Why using VMs for stuff that can run in docker? It's a waste of ressources … isn't it?
Haiku?
Legend ❤
The ability to install MacOS will go away because at some point Cuppertino will simply decide to stop compiling x86 MacOS when they deprecate all of their still currently supported Intel Mac lineup.
Great video! Thanks
what's the minimum HW requirement to run 3 os at the same time?
Without watching the video, I’m gonna go out on a limb and say the host is macOS
Dave, I think you might want to take a look at Haiku OS. I think you might get quite the nostalgia and some great content out of it even if the video is not dedicated to it. I never got to experience BeOS, but I do have Haiku on a eeePC netbook that works great!
I have done some VM stuff but with unRaid. For the longest time I was trying to do a gaming VM with unRaid where I could connect to it either over the network or the internet and would have very little lag. Much like the gaming PC in the cloud Shadow PC does it. But for the longest time it was just about impossible. One when I tried it for the first few times I didn't have a iGPU for unRaid it's self to grab. Secondly I have a Nvidia GPU and until a few years ago if the driver installer even got a wif of it trying to be installed in a VM it would kill it's self and give you an error. Windows would just mark it with error 43 in your device list. Nvidia finally unlocked it at the driver level so that game dev's could test their code out on their work stations in a VM and not brick the whole computer. But I finally have come to the conclusion that I can't access it over the internet without the real high ping with the current RDP applications that currently exist. As for over a lan; it's doable but again the latency even over a lan is pretty pad. They only feasible way to do it is to have one tower with two of everything connected to it physically. Say you and your significant other have your own VM instance and it's running on one physical PC.
Is it possible to do the pcie passthrough with a windows hypervisor, so for example pass through an HBA to a truenas VM running on a windows 11 pro machine, and if so, how would I go about it?
I also have a low pitched voice like you and I like the way your voice comes out on your videos. May I asked what microphone you use? Is there something else that helps your voice, like filters or improvements software like Audacity?
Thank you. You have inspired a solution to a resource problem I have at work. 🙂
Dave, what surgery did you get on your spine? I was trying to find the video and i can't seem to find it.
How is gaming on that Windows VM?
As someone that is also autistic (like you, I think):
I know nothing about computers, but I understood what was being said here. You have a way of describing things succinctly but also clearly.
Well done!
Excellent intro to virtualization video. A video on clustering ProxMox would be awesome for those that are considering running this in a productions environment. We utilize a multi-node cluster in our production environment with external all-flash arrays providing storage that is accessed via iSCSI and NFS. Spinning a VM up for a quick test environment is very useful. Thanks for making this video to highlight the power of ProxMox and virtualization.
Inquiring minds want to know how much your Proxmox subscription costs a year. 🙂 LOL!
I wonder how he is installing the latest version of MacOS in a VM on a Intel processor since Apple has switched to the ARM based Apple silicon and no longer supports Intel processors? Even when MacOS did support Intel it was a massive pain in the ass to get MacOS to run in a VM on non-Apple hardware.
Cheers for putting Hyper-visors into a nutshell 🙂
Dave taking mugshots to the next level 😀
this is super cool. what about gpu, will that work for gaming e.g. on windows virtual?
Very informative! Never used Proxmox before as I'm new to VMs. Gonna give it a try.
Thanks Dave!
Dave, this was excellent! Thank you!
I remember running OS/2 and Novell with in that on my desktop…..yeah that long ago. I was thoroughly geeked that I could have the Novell server, Windows, and the new Novell desktop OS all running at the same time. Those were sometimes back then. -Ted
