True... 10years ago. Now hyper V is the way to go for people want test VMs in Windows

Virtual box is fantastic! It’s not fast but for 99% of people being easy to use and requiring minimal prior knowledge makes it spot on. It has lost its edge a little now VMware is pretty much free. I do agree with you on the one point though. Getting a bare metal Hypervisor is the way to go. I use an old Cisco C220M3 with ESXi on and its great.

For linux-based hosts, yes, QEMU is better. For Windows-based hosts, it's still Virtual Box. Also, if you are looking to automate virtual machines spinning out using Vagrant, Virtual box is most compatible than any other virtualization system. Only Vagrant + Virtual Box combination lets you spin up a machine with additional custom volumes, for example.

KVM is a type 1 hypervisor, while Virtualbox is a type 2 hypervisor. The KVM hypervisor is part of the kernel. A type 2 hypervisor is also referred to as paravirtualization since it's not true virtualization. A huge benefit of KVM based virtual machines is that you can run them alongside the host OS and use the desktop of the host at the same time, just as you can when using a type 2 hypervisor such as VirtualBox or VMWare Workstation. With other type 1 virtualization such as ESXi and Proxmox, the entire machine is basically dedicated to the hypervisor and you are then managing it from a second device through web browser or other web based interface.

no it's great for using in general, not just starting out, sure you can't play 3d games but same is true with KVM as well unless you have another GPU to do full passthrough with, virtmanager also doesn't offer nearly as many options as virtualbox does, so if you want to change things like vram amount or vgpu type, you have to change the xml config which is really annoying and wonky with virtmanager. virtualbox also adaptively offloads work to consume less cpu cycles if the guest system isn't doing much work, which is more useful for end users with home PC's, it makes your host system more efficient while the VM is in the background, you can also explicitly set the util limit of the amount of cores you allocate to the system as well, with KVM you cannot, KVM was more meant for servers utilizing the full capabilities of the CPU for virtualization, which is great, but may be not as good for a resource limited end user pc. i'm not knocking kvm/qemu, it's amazing, but saying that virutalbox is inferior to it is like comparing apples and oranges.

I'm a VirtualBox user and I'm open to other options. QEMU is a faster solution, but given what you showed in the setup process, you're configuring the base Linux OS to support running the virtual machine (which is fine). I run VirtualBox only when I need to run Windows for something. I'm not sure I want a virtual machine service running when I'm not using any virtual machines. In other words, VirutalBox is an "on demand" virtual machine application I use only when I need it. I have Windows 7 and Windows 10 setup in VirtualBox and I haven't run Windows 10 in close to a month, now, and I haven't run Windows 7 even longer than that.

Yes, you're right. However, most of the work can be done in virt-manager. You just need to set up a squashfs "filesystem" there. With 9p support in your host kernel, you can mount it with a single command. Probably there exist some other way to do it as well with libvirt/virt-manager.. Or maybe the developers of virt-manager didn't do the proper job of adding this function, not sure.

Definatly gonna give this a try, I have been fed up with virtualbox for quite awhile. Thanks

One nice thing about Virtualbox is that the VM settings are stored with the disk images. So adding that VM in Virtualbox on another distro is trivial. KVM/Qemu isn't as easy I don't think (please let me know if I'm wrong). The VM XML config is in /etc/libvirt/qemu - can that file just be copied to the new distro? What about VMs with snapshots?

I'm glad you defined KVM. I'm still old-school and think "Keyboard-Video-Mouse"

Thanks! this is perfect! I use Ubuntu now pretty much exclusively but still have a need for windows for a few apps.... and one of them needs the GPU (Reality Capture) and QEMU pass through solves the problem that Virtual Box couldn't handle. This was easy to setup, thanks!

I find networking iin VirtualBox much easier, e.g. if I want to have a few VMs behind a router VM, I find the network set up much simpler. Individual VMs may be faster in KVM/QEMU but if you want to play with building a network behind a router VirtualBox is easy to manage.

I really want to like QEMU, but VirtualBox's network management is light years ahead of it (virt manager doesn't help accomplish this, either). To QEMU's credit, its network setup has improved tremendously in the last several years. Instead of being impossibly crappy, it has progressed to being just ridiculously crappy. It doesn't matter how much more performant QEMU supposedly is. If it won't let me easily setup network-accessible VM's, it has no performance at all. That's always been where my QEMU journey has ended, which is a shame. It's always been so close, yet so far away.

Yes, QEMU is the way to go for sure and it's a great way to host a hypervisor in a VM so you can run VMs on a VM on a host running QEMU. It may sound silly at first, but there's a lot of good use cases for doing this as well as making it a great way to do labs while you're learning about virtualization without needing a fleet of physical computers for it. Though you should make sure you have higher system specs for doing this. One use case I've had is deploying a VM to run GNS3 so I can virtualize network devices for doing modeling and learning labs. This meant all the network devices were running as VMs on the GNS3 VM on my Linux host running QEMU.

First of all, I must say that I'm a really big fan of your Channel and of Your work in general That you're trying to make computing more accessible For the average user And that you Have made for yourself an objective to broaden up our Horizon Beyond the Windows Realm I'm a Linux newbie and I like it so far so much so that it has become my main operating system of choice for daily tasks on my dual boot system And since discovering Linux I barely boot back into windows however, regardless of how Linux is wonderful, you can't escape the fact that sometimes you have no choice but to resort back to Windows and for that purpose, I've tried a few virtualization platforms and I must say That I totally agree with you that out of the bunch of all the available virtualization platform virtualbox is the most inferior And since my favorite virtualization platform Which is VMware and I know it probably sounds sacrileges for the unwavering Linux user but I digress and although it's possible to install it through the Aur its implementation can be very flaky at least on Arch-based distros so I've resorted to KVM however now I'm considering deploying a standalone virtualization server so I would like to ask you did you had some experience with virtualization platforms such as proxmox and alike and if so I wonder maybe you could be able to make a brief introductory guide for beginners in proxmox however if not I will understand and yet I would like to ask you please get back to me and tell me what do you think of my idea

Used VirtualBox for the last 2.5-years, made the switch to QEMU about a month ago on my desktop and laptop. Need a Windows box to run Excel spreadsheets for work. The change over was straight forward. Definite performance benefits using QEMU. Cloning and backing up QEMU is very simple. Finding no reason to use Virtual Box going forward. I did lose my Windows OEM license when I made the switch, Windows picked up on the hardware change. Enjoying your videos again, thanks for all you do.

there are many bootlegged versions of Windows 8.1 and Windows 10 free online and a few YT videos on how to get around the licensing during install.

Chris, I have a lot (30) VBox machines (all distros of linux) on my Win10 system. Each one serves a different purpose and all I run on them is Firefox. This approach does a nice job of keeping snoops like Google and Facebook from seeing other sites I use for affiliate stuff. I don't really want to create a dual boot system, as over the many years I've used VMs, Win updates always messed up the boot sector and I have to fix it.

Another option if you are into a GUI VM manager, especially for those on rpm based distros like Fedora, CentOS, Rocky, Alma, RHEL would be cockpit. But I rather prefer doing this stuff on the CLI with e.g. virt-install, qemu-img, and virtually almost everything with virsh. Last but not least vagrant is a great tool to kind of automate setting up your vm boxes.

Hey Chris, Great video as always. I had a wierd thing happen. I loaded up virt-manager on my Debian bspwm (BigDebian) machine. It would take 20-30 seconds to start as a user but would start immediate using sudo. So, I took my other computer which is the same other than being in a desktop case vs a tower case. I loaded my typical minimal Debian install and went through my procedure. Then I loaded virt-manager. It works just fine. I've done a lot of messing around with different apps and some compiling as well on BigDebian. I figure that I messed up something in the process. So, I think I'm going to use LittleDebian to test this stuff out and spare my main machine (BigDebian). Sorry to hear that you got sick. Covid is a nasty piece of work. I know of three people in my circle that have gotten it in the last two months. Two ended up in the hospital. I am self isolated which has worked well for me since I'm basically a social introvert anyway. I pray you get well soon. Take care and Stay Safe.

That sounds really strange. However, general delays can sometimes be attributed to DNS issues. It has to connect to the Host when launching virt-manager and probably where this is going wrong. Check to see if you have yourhostname 127.0.0.1 in your /etc/hosts and research connecting to session host. Also you can try to launch your VM direct from terminal using the corresponding QEMU terminal command without a GUI frontend. I'd be curious to see if this has a delay. Also, check to see if you get delays when issuing virsh commands in terminal. Start with listings and status command to see what you get.

That will bring me much closer to how and why. ;-)

I'm on Arch, and I made the good switch. Qemu / Virt Manager was more or less straightforward to install, and works like a boss. And with better control over USB forwarding. I can now run iCue to control the LEDs of my chassis and fans without a hitch. I no longer need to do a dual-boot, and may just eventually blow away the Windows hard drive, adding another 2TB to Arch Linux! Thanks for this.

Qemu with KVM is what convinced me to switch over to Linux. If I need Windows, I just spin up a VM with everything I need passed through. Didn't have to reinstall Windows or backup its other drives, just passed 'em through. I even made the ultimate recovery USB so I never have to install an OS on metal ever again.

So I dropped the Idea, because my Mainboard doesn't have Display-Out. I would really appreciate it, if you can explain me again, or even send me a guide. Thanks :)

If you are building a server definitely go with the qemu stack. However, if you need for small tests I don't think it is that good. For example, try to forward a port from the host do the VM....

Good stuff. I haven't used VMs much recently, but I was one of the first to give the thumbs up for VirtualBox. Competition is always a good thing and we end up the winners!!

Appriciate this so much! This Channel is Awesome!

as with everything it depends on your individual needs at one situation VBox will outperform QEMU, in other QEMU will outperform VBox some strenghts of VBox are running legacy systems, and networking different virtual machines together

What about bridging the VM's network with a wireless adapter? Virtualbox makes it so easy, but on QEMU/KVM its a pain. That is why I run VirtualBox on my laptops and QEMU/KVM on my desktops

The only problem I've encountered with QEMU is getting around some of the quirks involved with starting some games... there are still some titles (specifically FH4) that just won't start in the hypervisor. I'm sure there's probably something I can do to 'hide' that from Windows and make it 'think' it's running natively on metal, but I haven't had the time lately to figure that out. QEMU is definitely the virtualization tool for getting the most out of your hardware for VMs, though. Thanks for talking about it!!

did you create fixed virtual drive or dynamic virtual drive for VirtualBox? I've tried both and Fixed Partition has helped significantly in speed

I'm all for qemu, especially when I want to passthrough my second gpu to the vm (windows/linux/*bsd). KVM + Qemu + io_uring + nvme storage is close to the barebone machine in I/O performance. I'm using the combination in EPYC server and VM can get 1-2 GB/s write performance with less than 5% CPU.

Was wondering but, on VirtualBox isn't there in Paramters -> System -> acceleration: the combobox allowing you to choose which kind of hypervision interface you wanna use for your VM ? I see in this combobox it proposes KVM aswell. Is it the same ?

I always used vagrant for quick setup of development boxes (Nowadays a lot transitioned to docker), and virtualbox as provider always seemed to work good enough :)

Two questions: 1) What's the QEMU experience like on a Windows host? You briefly touched on how that's not a great experience, but do you have a video about that? 2) What's the QEMU experience like if you are running on a Windows host, with a Windows guest? Your thoughts would be greatly appreciated. (I understand that you are showing a Debian-on-Debian example, but I'd be curious to see what the qemu experience is like if it was say Windows-on-Windows (WITHOUT Windows 10's WSL because I'm still running Windows 7.) Thanks.

Awesome video, thanks for your cocntent! I have several questions. 1. Can you compare the same but not using KVM, like if you use qemu for windows images, does it work faster? 2. Can you passthrough hardware in non KVM images, like video cards? Like for example if I want to use windows for playing modern games, can I use qemu and passthrough the Video card there and play from there? 3. Can I use qemu on windows, you mention the version is not so good, but does it have the same features as being able to passthrough hardware?

i don’t know much about this kind of stuff, so here’s my question. does the hardware passthrough mean that the vm would be using my actual gpu/cpu instead of a virtualization of them like virtual box does? i had a use for a vm a few months ago but just couldn’t use virtual box since i didnt have good enough specs on my computer to handle that

it just throws me off that I have been working on single gpu passthrough with kvm and all of a sudden chris posts this. XD

Hello Chris, Thank you for the wide variety of ideas you share. Wondering with Qemu, I know you're not fully involved in "Mac", but using Qemu as Hypervisor on macOS - may a video, or ideas to do it right in your realm? I'll appreciate any links, feedback, e.g. Have a great week!

Can't take videos like this serious. There's no need to put down virtual box unless you have an incentive for it. Just say you prefer something else and that you recommend this and keep it moving.

I rarely use VMs, but the last time i used it, qemu had no 3D acceleration, so it was a very sluggish UI experience. Virtualbox has working Directx acceleration on windows.

Correct me if i'm wrong but I'm guessing more advanced gaming is possible with the PCI passthrough in qemu, say if I wanted to use a Windows VM for modern gaming? Also how do the Win 9x systems run in qemu? Virtualbox and VMware have failed me with those when I try to load them for classic gaming. They technically work, but the driver support doesn't exist which makes the older games run not so well.

Nice one Chris! Do you have VMware Workstation? If so, can you run the same test on that for comparison? I'd be curious to see how QEMU compares to that.

Actually it's kvm that's doing the work. Qemu is just an interface.

No lol. What the hell? And you got 15 up votes? KVM is a few kernel functions for activating hardware accelerated virtualization on the CPU and trapping i/o requests. QEMU is the engine that emulates the hardware such as the graphics, sound, motherboard, disk, etc. When the virtualize machine runs code on the CPU, and the code tries to access input/output, the KVM hypervisor traps it and sends the request to QEMU which handles the hardware emulation. QEMU and KVM are both required components. You cannot use one without the other. Virt-manager and GNOME Boxes are the GUIs for this stack.

I also get faster boot times than what the video shows across multiple Linux distros, but if you want to sell something, you should really overdo it. Personally i think the Virtualbox boot attempt is unjust vs QEMU, since its the first attempt that loads your data from your non-volatile to your volatile storage, and the second attempt takes advantake of this and the higher speeds.

Thanks, Chris! I'm definitely switching.

Both Qemu and VirtualBox have different advantages. And, I'm not a noob. I've been writing software on multiple versions of Unix, on VMS, and on CPM, DOS, and Windows, and I've been programming for over forty years.

Is it worth running Win10 desktop as a VM? I like the idea of being able to use snapshots for system backups. But can you get comparable performance this way? And what are some of the gotchas involved (like PCI passthrough, etc)?

It's something like this: sudo pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat edk2-ovmf ebtables iptables libosinfo (dmidecode). Ebtables vs iptables, I think ebtables is the recommended firewall. dmidecode is optional, can't remember what it does. Libosinfo lists the OSes when Virt-manager asks what OS the ISO contains. Very short list otherwise. I don't think Win10 is even on that default list. Then theres the permissions. To the image, if you run that from other harddisk (not from /var/libvirt or whatever it is). You need permissions to access it all the way. Not just the folder it is in, the whole tree structure. So Virt-manager can traverse there. I don't remember the command.

Hey man, It works great and without any problems.

I never been able to use QEMU, I didn't know that there are font-ends for it. I'll give it a try the next time I need a virtual machine. Thank you.

Hi Chris! Awesome compare and runtimes. Do you also tested Microsoft OS?

What Linux Operating system did you use for this presentation, I'm interested in trying it out. I currently have Linux MX as a daily on a Dell 630i.

On a Windows host, QEMU is WAY slower than VBox. I installed Windows 10 with both of them, QEMU had 5 CPU cores given to it, and VirtualBox 1 core. QEMU had more RAM given to it too. And I didn't even start the VirtualBox VM until QEMU was at the "Getting ready" installation part, giving QEMU a huge head-start. VirtualBox completed the installation before QEMU. I couldn't put acceleration on QEMU, so that may have had something to do with it. Before this, I was trying to make QEMU work for at least 4-5 hours, and this is the one where it finally worked. VirtualBox just worked without hassle. Also QEMU used around 65% CPU ON IDLE, and VBox around 5-10%, and I couldn't even use the QEMU VM because it was completely frozen.

My build time went from yawning and watching paint dry to about 17 seconds. I'm a QEMU believer! Also you mention VB might be better for noobs but, if you don't mind running Ubuntu as your VM, you can get Multipass from canonical which is a fire-and-forget wrapper on top of QEMU, and it works on Linux, Windows, and macOS. Two 👍🏼👍🏼 for QEMU-based VM solutions!

I have been using VMWare and decided to try Hyper V, once I setup the machine and tested it, removed VMWare. What a difference in performace.
