Ultimate Guide to Virtualization: Run MacOS, Linux, and Windows all at once on the same machine!

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.

More Proxmox and virtualization videos please. I think a lot of people with old notebooks and PCs can benefit from this and not just homelab folk.

This episode was more fantastic than your other fantastic ones. I'll watch it again to take some notes.

Dave, I’m a VMware/Nutanix engineer and this is spot on for Great video !!!

[larryblount]

VM explained the way only Dave could do. Huge thank you. I will give this a try!

[jasonrubik]

what a treasure ! I have been meaning to setup virtualization for years, and this might just be the motivation that I need ! Thanks Dave !

VM ware sure is fun. Back as a poor college kid in the 90s, I had to dual boot a machine if I wanted to play with more than one OS on the only machine I could afford.

Great video, Dave. I'm starting development with docker containers for the first time in my career (shockingly enough), so I'm trying to learn more about virtualization techniques, Type 1/2 Hypervisor VMs, "microVMs" (like Firecracker), and docker containers. I appreciate you sharing your set up and some details on how it all works. 👍😊

This was a very informative video on virtualization. One single sentence gave me a great deal of information. You mentioned that installing Hyper-V on windows actually installed below windows and I'm guessing would not alter the existing installation of windows. This makes it very easy for me to all Hyper-V to my system. Thanks loads.

[aluzza]

This is my favorite video you've done so far! I would really love more virtualization content! Thank you!

[SpragginsDesigns]

I really enjoyed this video, Dave. Thank you for what you do. Definitely one of the best channels on YouTube.

[sorbpen]

Your choice of music for this episode was spot on <3

Thank you Dave :D

[JureGrbec]

This is amazing, I am just installing Proxmox, to run Windows and Linux at the same time, and then this video pops up. Thank you Dave.

[fredflickinger]

Thanks so much for showing all of the potential with Promax and bare metal vs hypervisor installations!

[smalle]

More of this content please! I would love a more in depth follow up that goes deeper into your setup and any hurdles you faced in the process.

I have been working with ProxMox for a few years now and its performance and ease of use is impressive. I currently run it on a fan-less i7 with only 32G RAM and 500G SSD and it reliably hosts a firewall and 6 other virtual systems. ProxMox doesn't require expensive hardware, even low power fan less computer or an old laptop will work as long as it has sufficient cores, ram and hard drive space. Thanks for another great video, I learned a lot. Any chance on discussing how you got the Mac OS to run? I have a number of old obsolete Macs that could use new hardware.
I had difficulties installing ProxMox on a Windows server 2019 hypervisor. I didn't want to corrupt our company's server, I assumed virtualizing a virtual server may not be tolerated. I was impressed ProxMox tolerated Windows 11.

Nice setup, Dave. I'm running a similar Proxmox environment with pfSense, TrueNAS Scale, and a Debian VM that's handling three 3070s. Ran into some speed issues with pfSense's virtual NICs(even with hardware offloading disabled), but dedicated network cards slotted into the VM sorted it. It's been rock-solid for two years, and I'm maxing out a gig on SaskTel's fiber here in Moose Jaw with this rig even with all the goodies enabled like pfblocker, wireguard nordvpn

Great video Dave! Thanks for sharing it with us!💖👍😎JP

[Kauffy]

By far, the most relevant (to me) video of yours I've seen-- I just built a ridiculous machine with virtualization in mind.

[TheTarasevich]

Cool setup! Proxmox, TrueNAS - all as I like. And virtual TrueNAS done in a proper way.

[vaibhavkumar-ustw]

Thanks Dave, learned something new today.
