Very helpful video! I've been using VirtualBox for about 8 years now and am slowly making the switch to this as performance is supposed to be better. I tried Qtemu as the graphical manager, but I think it's garbage and virt-manager looks like it will be a lot better for me! I'm figuring out the concepts, like KVM, QEMU, and virt-manager and how they are all relevant, and I think this video explained it well! Now I'm starting to piece it together and looking forward to seeing if the experience is any better performance-wise! That doesn't mean I will never use Virtualbox again, but I will probably prioritize QEMU now. As for VMWare, I can't stand it either for the same reason, so I will never be using it either unless I absolutely have to! You're the first person I've heard to also have this opinion.

Gnome boxes is also a great way for newbies to introduce themselves to qemu-kvm virtualization. For those who choose to use qemu-kvm instead of gnome-boxes you have to install Virt-Viewer to get sound and play games on your virtual machines (Virt-Manager will not allow sound), then install mingw32 or mingw64 on the guest OS for guest services (usb, file sharing, etc..). An easy way to deploy virtual machines for newbies is to use gnome-boxes to create the virtual machine then import the saved image file into virt-manager, then use virt-viewer to fully use the image.

Since Ubuntu 20.40 3D acceleration works in Linux guests. Xonotic Ultra 1080p 50-60 fps on a RX 460! Not that I use it for gaming, but this means that desktop is much smoother now and there's no difference to a bare metal installation. So, for example if I need to design reports (jasper) the virtual machine is very responsive. A tremendous improvement! I use KVM/QEMU exclusively. No other hypervisors. I hope one day there will be some sort of 3d acceleration for windows guests too.

I stopped using virtualbox when building from source became a pita, circa the oracle takeover.
Libvirt is a wrapper for managing both xen and qemu with the same commands. My bias is to avoid wrappers like that, because it's an extra layer of confusion if something isn't working. But it does appear to be -the standard way,- and lots of software (like stuff that mounts qcow2 images on your host machine) uses it anyway.

Hello, I've been trying to create and install an OS like CentOS in KVM through nested virtualization in VMware Workstation 16 but I'm not able to browse and access my ISO files which are inside my Windows from KVM. Would you please let me know how can one access the ISOs from the Host Machine. Yes I can download the ISO from within the VM which is CentOS VM in my case but how to access from the host I've no idea?!!!

I have no idea why would anyone take virtual-box over KVM/virt-manager. Same goes for virtual-box over Hyper-v(windows) both KVM and Hyper-V are type 1 with pass through capabilities. I can literally play any games on my Win-VM. It's the real way to have side by side 2 OS. This guy is using console to input commands in KVM but you can go all of this easily with the Virt-manager GUI.

Thanks DT. I am using virt manager for a while, but only to spin not graphical linux machines, usually with vagrant.
I tried to install some Linux distros with graphical interface, but having very slow video and audio.
Tried different drivers, but no luck so far. Do you install some drivers on the Linux guest?

The performance difference between KVM and virtualbox is massive. Even vmware is slower than KVM. The only problem with KVM is the lack of 3D acceleration in Windows guests, but there are ways to minimise the impact. On Linux guests, 3D works so there's no need to even bother with alternative solutions.

THANK YOU for actually talking through what each piece of software is for and why, instead of just saying -install this this and this- like so many other people would have done. I always love to learn about how things work instead of -this just works-.

Just installed Qemu/KVM on arch a couple days ago. Seems a lot cleaner running than VirtualBox.
I'm going to try a virtual windows 10 in it soon. FWIU i can use my existing windows 7 key to install 10 as long as its the same service pack.
