Different Types of Virtualization

I understand,
Type-1 (Bare-Metal) : Hypervisors like Qubes-Os,
Type-2 (Hosted) : VirtualBox w/proprietary BIOS, QEMU (free PCIe passthru)
Docker Container

But what is meant by KVM hypervisor available only on Linux? Windows only has Hyper-V? Where does WSL2 fit in?

thanks for the explanation, cheers!

I tried xcp-ng, but the boot from USB install media ends with reboot without any message. Safe mode is way too slow, like screen scrolling messages up during boot takes 1 sec to scroll 1 line up to free space for the next message and I did not have the patience to wait more than 20 minutes and safe mode was still booting. I now use small Arch installation with kvm, libvirt and qemu. It is a lot of fun and frustration at the same time. I managed to successfully passthrough my Nvidia card. That took couple of days.

you didn't mention the main advantage of containers which is that you can share containers and they can run everywhere..

Is hyperV a type 1 or 2

Q: who you see Openstack in this Area, i saw this often as alternative to VMware, whats your exp on it

Why would companies bother buying vmware when open source solutions like Xen are free?

docker isnt the future, its already here. Docker uses systemd cgroup and namespaces to isolate different linux apps. As such it is way better than using VMs.

Finally... A straightforward, no BS overview focused on the most used choices within virtualization/containerization, their practical application, and comparisons of how each relates to another.

Great video and even better demonstration of knowledge related to these technologies.

I don't understand why there isn't other content like this among other reputable content creators. It seems like most other videos are more geared towards a singular view or comparison.

👍

Thank you for this video, Now I can do pci express pass through for free, Something that should come with and be expected in virtual machines.

Where does the standart Windows sandbox stands? From description it is container based. Is it any good compared to alternatives?

Thanks a lot, learned a lot!

What[ forum are you on. I would like to talk

Eh, even projects that contain outright malware in them are open source nowadays, and nobody bats an eye because just nobody looks at that software. Things are as secure as they are reviewed. You really shouldn't claim that OSS is more secure.

"You're typically not gonna see a type 1 especially at a home desktop"

Uh, the very prolific WSL2 for consumer windows would like a word..

If you [somehow] haven't heard of it, it's like Qubes except your interface in your regular windows install, and you can just run any native linux code through the windows ui on the linux sibling hyperv kernel/s

Not for security, but ease of use and is pretty stellar. P9-facilitated, seamless, two-way filesystem mounts, cli interactivity, and graphics & raw disk passthroughs.

But only for linux and no real control over other block devices for the linux kernel (but it is a real kernel and ive compiled my own to get wireguard working and it operates very close to metal).

Macs have integrated and dedicated graphics, could qemu work for gaming?

I would say windows users minds and data exist in virtual matrix style as microsofts cashcow slaves

KVM is type 1

It's worth mentioning that with PCIe passthrough, you don't generally need to buy a second graphics card if your CPU has integrated graphics.
