Plot twist: He's actually using linux mint in a VM on windows 10

Hey MentalOutlaw, you might find the 'Noise Removal' tool in audacity useful when recordings go bad. I used to own a very cheap mic and it'd always pick up a shit ton of noise, but audacity filtered it out pretty well. Keep up the good work!

I thought this was a Luke Smith video... You know, the thumbnail...

Update & correction: the command should be `sudo addgroup libvirt`, so everywhere use `libvirt`, NOT `libvirtd` as the group.

This channel will blow up in any given time

I have long experience with KVM. I also had same difficulty when i started to use KVM. The reason why it was hard is lack of knowledge for modules of libvirt(libvirtd sock), virsh(definition file XML you may see in GUI), qemu-img, virt-manager, cloud-init and VNC. I do recommend to find information about the above keywords. And please try to be adopted to virsh command line if you only run linux server because virsh allows you to access guest machine's console directly without VNC. extra tips for performance. - You need to install virt-io driver for disk, network and GPU because it is fastest driver. - If you need GUI based guest host, you must go with PCI paththrough. I've never gotten better performance than this composition in VMware, VirtualBox and Hyper-V. VNC based connection is very poor performance even you are running on localhost. But it requires a lot of information because you have to understand how linux's device works because bare-metal system is always different by having different hardware. I could run guest OS with Nvidia and AMD graphic card for MAC OS, windows and Ubuntu. Reference access.redhat.com/documentation/en-us/red_hat_enterprise_linux/5/html/virtualization/chap-virtualization-pci_passthrough. - Everything you will try is can be done with KVM but you always need to have knowledge for the technology. If you

The things that you talk about technology are 200% connected with my heart

thank you OP and comments section, i just got stuck trying to use virt-manager earlier 🙏

Here's a tip, switch from Listen Type Address to None in Spice menu Change Video to Virtio and tick enable 3d acceleration Go back to Spice menu and enable OpenGL. There you have now all draw calls ran directly on your GPU If you want to use other GPU (like a dedicated) ran virt-manager with DRM_PRIME=1 (or other number according to gpu) And pick that GPU in Spice menu. Very Sadly this doesn't work with Windows guest, because GPU passthrough not only is harder to do but also needs hardware support for passing through feature, While this VirGL method i told before is hardware agnostic

Kenny I am hoping you consider an update to this in the near future...your explanations are clear and I watch every one you produce. Thank you.

Are you planning to make video about doing gpu passthough?

As one of the commentors, thanks a lot bro.

I started with virtbox too... Then switched to qemu when I wanted to do pass through. (I run a windows vm on linux - so I can run cad on my laptop. Passing the dedicated video card to it.) It has been rock solid. (not that I remember having any problems with virtbox)

Happy 6k

cool video. Will eventually try this to make virtual machines and maybe pass in an extra gpu to make it even faster.

About your comment at 5:27. Actually there is no such difference between modern virtualization. VMware, Virtualbox, KVM, Bhyve, Xen and Hyper-V all run the guest code directly on the host CPU (with the help of the Intel VT-x, AMD-V or other virtualization extensions for various architectures). Any difference in performance are due to other "bottlenecks" in the hypervisor, for example quality of hardware emulation and/or use of paravirtualization.

kvm qemu has been fairly easy and reliable for me for the last decade. I don't know what trouble you've had with it, I'd assume just a missing package. the most trouble I've had with it was long ago when I needed to install a custom networking script to set up a wan connection to a router in a vm. that custom script hasn't been needed in a very long time and everything just works. it's very reliable and easy to use, and doesn't require a gui.

it took me a grand total of 2 weeks. 2 WEEKS. to get KVM passthrough working propperly. and a new graphics card for a 1x slot. And figuring out how to map samba shared. Lots of headaches but I haven't touched it in months and it runs like a champ because I stay on the arch LTS kernel and blacklisted nvidia driver updates so it doesn't kill my linux install.

Aye, I also struggle with Virt Manager. But every time I am tempted to switch to VirtualBox I remember the joys of working on a terminal the size of a mail stamp because VirtualBox won't resize the damn window unless you have virtualbox-tools installed (not compatible with 90% of my guest VM) and I stick with Virt-Manager

Gnome boxes seems to be the easiest choice today and if im not wrong you can also run a gnomeboxes vm with virtmanager

Have you tried using qemu in command line? I'm a smoothbrain and even I think it's easy

flawless distro hopping in virtual box. with virt-M I have issues when I exit and go back again, it seems to need a fresh install every time! this shouldn't be some problem a user has to "fix": surely out-of-the-box basics dictates that a virtual machine doesn't do that!

I discovered QEMU/KVM out of necessity because as of the time this comment if being written, VBox doesn't support Ubuntu 22.04. So I had to install and learn how to use QEMU/KVM (with the GUI)and it's not bad at all.

Actually gnome-boxes is the noob virtualization in my opinion and if you're running fedora it's installed by default and It just works! I think the main reason people use virtualbox is because unlike qemu it also work on other platform so people coming to Linux automatically goes for it while in fact it's much harder to use than something like gnome-boxes and don't offer the same extensibility of virt-manager and it's slower in my experience. If you switched to Linux please do yourself a favor and switch to qemu.

I'd say VirtualBox is way easier to use. But QEMU/KVM + VirtManager/libvirt is more powerful to like do advanced things like hardware passthrough for GPUs and finer control over virtual networking. Altough, I admit I'd like to see libvirt improve to be more accesible. For example, is somewhat complicated to do a "linked clone" of a VM, while in VirtualBox is straighforward. Also I have had some problems with EFI in libvirt.

Hey Mental, VirtualBox doesn't even support software emulation. It also directly executes code on the CPU. Btw I use virt-manager.

Are you planning to make single gpu passthrough tutorial?

Would be awesome if you could show how to install and setup KVM + qemu + virt-manager on Gentoo

Nice guide...though i'm wondering same about web based virtualization solution is good ? PS : background noise is little ...

What happened to the microphone? GNOME BOXES (KVM) works out of the box for simple scenarios. But yes, maybe VirtualBox is easier for GPU acceleration and networking

Does anyone know how to bridge the network on vert-manager as I have tried all different kind of network settings and cant get it to bridge as vert-manager always has this strange allocated IP address for the VM so its not possible to SSH into the vm which it does simply on virtualBox but I dont want to use virtualBox vm's as I want to SSH into VertManager vm's?

There is no need to promote the use of KVM, it's what 80% of the internet runs on (AWS, Google Cloud) and even for enterprises and big corporations hosting their own servers - Nutanix AHV is a KVM-based hypervisor for businesses with added features. For small businesses there's Proxmox, so KVM is literally everywhere. If anything, you'd have to fear for the survival of VirtualBox .... but... do we really even want an Oracle product to survive?

Would you be interested in revisiting the QEMU/Virt-manager/Virtio stack? I just spent the weekend getting Win10 and Pop_OS working with GPU & peripheral pass-through, getting better performance than I would bare metal surprisingly. Would be willing to help you give it another shot if you are at all interested.

Good video.

TBH, virtualization is not tech noob stuff. I wrapped my head around virtualbox for quite some time before knowing which buttons to push and which to not push. QEMU alone is quite jarring, but once you crossreference the options and their arguments with your past experience in VMware or VirtualBox, you can get around it (still can't boot a VM in UEFI mode on MacOS). Virt-manager adds another layer. When you imagine the average Racecar Johnny which doesn't even see the installation process of windows because he buys a computer with OEM Windows, you can be sure this isn't going to be simple.

I just tried VirtualBox - seems to just work. Then I read about nested virtualizations...recursives all the way down! So there's an extension that allows the VM to share files with the host? Cool - trying to figure access to SD cards (running Kubuntu as VM)..cheers.

I have 10 guest OS ..can u please tell me how to Start/stop host on a schedule

i just installed gentoo in kvm but i ran into the issue sort of what he ran into at the end of the video... i cant get the the full screen to work and the "auto resize vm with window is grayed out" and i cant copy cut paste into the vm... i know i have to setup something but not sure... its driving me crazy that i cant seem to get this to go! i really like kvm and use it alot unfortunately im new to gentoo if anyone have any ideas please reply...

brosky what are your thoughts, on the Windows Linux Subsystem 2? supposedly you can run a linux kernel on your machine... so you cam run linux command line tools on windows, they even have a new windows terminal that you can customize

Really nice & in-detail video!!! While installation I didn't get the bridge network option as you....And now I am unable to have internet connection on my virtual machine. Can you please give a solution

Hi ... If I simulate windows and download drivers for my hardware ... Is it possible that suppose a level 0 kernel malware can influence my hardware through the virtual machine?... Just curious thanks

You speak that you released the virt-man, do You have a github account ?

The simplest way is gnome-boxes, if you need to tweak settings you can tweak that VM using virt-manager

You got copy/paste like Virtualbox?

What if your using RC (gentoo)

I am on Linux Mint Cinnamon 19.3. I followed the installation instructions provided in the video. When I launch virt-manager I get the following error: "python 3.4 or later is required, your's is sys.version_info(major=2, minor=7, micro=17, releaselevel='final', serial=0)". The command "python3 --version" gives me Python 3.6.9 as my version, which is later than python 3.4. Looks like a bug to me. I tried uninstalling virt-manager and re-installing via Software Manager. I noticed that in Software Manager it states "NOTE: the GUI is still considered experimental." Maybe it is not fully baked yet.

Maybe you can make a video about how to share a folder. Share a folder is quite troublesome. Peace.

also you should check out a suckless distro like morpheus or sabotage linux

I use vmware and its has worked issue is installing vmware tools on my Mx linux.

agree, i dont even understand what to search for getting info about how to use virt-manager

I use virtual manager for gpu passthrough with mac os vm, and windows 10 vm. I would never use virtual box. I'm able to play vermintide 2 at 40-60 fps on this old 3rd gen intel cpu with nvidia gtx 1060 3gb inside the VM. My hardrive being even older. I won't give up linux for mac or windows ever again.

I can't get the guest OS to use my actual display resolution, and can't find anywhere how to force the guest display to be a certain resolution :P The guest is not a Linux/X11/Windows so none of the information I found works for changing from within the guest

i use virt manager to play roblox on linux lol, besides sudo apt install virt-manager, reboot and sudo systemctl status libvirtd is all it takes to install it

Hold up, you are using a debian based distro?

Gnome Boxes on fedora 34 seems to work well enough for my W10 CAD/CAE VM. UI seems smooth enough even without proper GPU acceleration, so maybe old games would run well too (haven't tried yet). As I understand it, Boxes is just another front end for KVM/QEMU with some sensible defaults which made my W10 VM "just work".

Always did that since 2013 and never looked back to virtualbox again.

Hey mam just remember or investigate about the meltdown vulnerability on Intel CPUs

I wish it had seamless windows.

mfw no `sudo systemctl start --now libvirtd`

Now amateurish that´s a thumbnail
