Ditch Virtualbox, Get QEMU/Virt Manager

In this video I show you how to setup QEMU/virt-manager with KVM which is a better virtualization stack than virtualbox (faster, scales better, and supports more advanced options like GPU passthrough and CPU pinning.)

VMM does almost no work, same to libvirt. They do only calls and creation and modification of vms, nothing more. Everything else is in qemu (calls to run vms on kvm and drivers) and KVM

[@eideticex]

That's not entirely accurate. There are two pieces of software you think of when you hear virtual box. There's Oracle Virtual Box and there's an open source Virtual Box. Both are generally at parity with each other but the open source variant can be used directly with a hypervisor, zen or kvm configuration for full hardware instancing. A couple years ago I abused that to no end to create sandboxed VMs for video games instead of using wine/proton, as in no desktop or taskbar, just explorer.exe and supporting infrastructure (like drivers) allowed to run in the vm. Worked extremely well, only stopped because proton and wine have got really freaking good over the last couple years.

Keep in mind the instructions for starting the service and editing that config file don't apply if you use systemd (which is the default on basically every popular Linux OS). You need to do "systemctl enable --now libvirtd" (this both starts and enables the service). You don't need to edit the config file at all. Also you may need to change some bios settings to enable virtualization, on an AMD board all of these should be enabled: SVM - Enabled Iommu - Enabled AES - Enabled AER Cap - Enabled That's required for GPU passthrough. Also note GPU passthrough is a huge pain-in-the-ass if you only have one GPU.

This was what I swapped to when I went with my home server a while ago and got tired of dealing with VMWare. Me and Oracle have never been best friends, so Virtualbox was never an option, and virt manager became a game changer when I tried it. It has built in QEMU management over SSH, meaning you can easily get at it from anywhere and not worry about any other security than your basic SSH. Only drawback to it is.... No Windows version of Virt manager exists, so this is one where I keep a Linux VM on my Windows machine just to do remote management.

As for X fowarding a window, I haven't looked into that for Windows, but it is tempting. Still though, that Windows box is very Linuxified, Cygwin is installed so I can SSH into it to fetch files when I am not home for an example.

"A _little bit_ of RAM." *[Casually drops in more RAM than most people have on their entire computer]* Actually... 16 threads + 32GB RAM _is_ my entire current computer. And even that is leagues ahead of every previous computer I've ever owned. I've been screwing around with PCem recently, which has reminded me of what things were like when I was a kid, such as having to use every trick in the book to push running applications into the upper and extended memory (where most of your truly enormous 4MB or possibly even 8MB of RAM resides), to free up every single kilobyte you possibly can of DOS's precious 640KB of conventional memory so that your games could run. After fighting tooth and nail to liberate those precious 60-or-so KB to stay above the 600KB threshold (using a mere 40KB to run the core of the OS), it really puts into perspective just how insanely far things have come. Imagine telling someone in 1993 - when RAM was $30+ per _MB_ - that a person's single, average-tower-sized PC would have literally 5.5 _MILLION_ dollars worth of RAM in it.

As much as I would love to use Qemu, I'm afraid to say from experience that it is only worth using if you a) don't care about graphics performance or b) have a second GPU to passthrough The reality is that Qemu occupies both places of best and worst virtualization stacks for graphics performance. If you pass through a real GPU to Qemu, it can blow its competition out of the water and get you graphics performance that can rival bare metal. However, if you, like me, do not have a second GPU, one of your only options is to use QXL which is like a virtual GPU. Unfortunately, QXL's graphics performance is absolutely pathetic as it lags even when you drag program windows around the desktop, to say nothing of its nonexistent 3D acceleration. It is literally eons worse than even virtualbox, which itself is eons worse than vmware's 3D acceleration. I am aware that there is one other option besides QXL and that is single GPU passthrough. However I do not even consider that an option because you won't be able to use the host OS while the VM is running. There is also another caveat which is that setting up shared folders is much more manual with Qemu than either virtualbox or vmware. Personally I wouldn't mind this if it meant I could get better graphics performance, but as it stands now it is only the icing on the turd cake of my experience. I WANT to use Qemu, but only virtualbox or vmware can provide me with bearable desktop performance at the moment.

[@HyperMario64]

It is surprising that one GPU cannot be used by more than one system at the time. Like, really really bad design. Usually you need to have your main GPU available on the host as well, it would be silly otherwise.

​@@HyperMario64 Right, thanks for reminding me. I forgot to mention that there is a 3rd option available only to Nvidia users - VGPU unlocker. It enables splitting the GPU cores on consumer-grade GPUs like Geforce like you would split CPU cores and share only part of them to the VM. This is normally only allowed on datacenter-grade Nvidia GPUs because Nvidia (sincerely **** them) want you to buy their more expensive GPUs which do not have this software limitation. VGPU unlocker allows you to use this feature on normal GPUs as well. This works only on a subset of consumer-grade Nvidia GPUs and mine is not one of them unfortunately.

One word of caution, having high framerates didn't equal to the responsivenes of the game. Had to either choose normal fps or not feeling the input lag. It was slight, but noticible, even though I tinkered with the cpu settings a lot. Might be a problem of having 7770k tho, since it has 4 cores 8 threads. Also tried limiting the processes on host to only one core, this might be a good trick for somebody looking to optimize performance, and it can easily be done with a simple bash script run by qemu on startup of the machine, and reversing its thing after shutdown.

For shared folders and bridge networking its a bit hard to achieve with virt manager. So when i need those features i use virtualbox

[@nepjr_]

You can use Samba to create a network based fileshare, and even access files from your phone or tablet (granted they have apps that support SMB/CIFS protocol) that virt-manager can access pretty easily

[@TheFrantic5]

The option to share host folders is in the +Add Hardware menu. I just discovered it today, and I don't remember seeing it before, so it might be new, and I haven't checked to see if it's sharable between multiple VMs at the same time.

[@navaneeth6157]

@@TheFrantic5 What is that option called? Filesystem?

[@TheFrantic5]

@@navaneeth6157 yes. I haven't tested this yet as I have a new system and I'm lazy, but you'll need to have your shared folder on the host as the source path, a made-up label as the target path, and you'll need to load these modules {loop,virtio,9p,9pnet,9pnet_virtio} onto the guest with modprobe. Afterwards, you use # mount [targetlabel] /path/to/place/shared/folder - t 9p -o trans=virtio to be able to place the folder where you want on the guest. Plan 9 is an old remote file system protocol from what I've read, but it should do the job. Unfortunately it's not one-click like virtualbox (and originally it thought it was, which was why I posted it) so if you need that functionality (as well as connecting to Windows guests) you'd be better off finding a libvirt samba tutorial. Or just use what works.

[@anthonyobryan3485]

Dead simple bridge networking is why I have always chosen VirtualBox over KVM. With VirtualBox, bridge networking is a couple mouse clicks. With KVM, unless things have changed, it was a massive gauntlet of system configuration changes and networking tweaks that were all but guaranteed to make a system stop working. I really, Really, REALLY want to ditch VirtualBox, but its incredibly easy bridge networking is why I stay with it.

Newest versions of linux kernel disable the KVM virtualization for security reasons.

I like QEMU, but it definitely needs a more streamlined install/configuration like VirtualBox to sway your average user into moving over. I also don't like how it has to modify your iptables in order to access the internet in VM's and bridged configurations (instead of NAT) are even more of a pain. Want to use UEFI BIOS for Win11...another layer of configuration/installs. VirtualBox is much more clean when it comes to installation/configuration, and unless you want a gaming VM or need to have the most secure VM, it's not really worth moving over. FOSS is the strongest selling point for QEMU imho.

@@1yaz Because I don't really believe that anyone would sacrifice crap tons of performance.. Then claim they are doing that because a normal mapped drive, which is essentially the exact same thing from a user perspective as having files locally in your C:, is somehow a PITA.

The trouble I'm finding is that my Windows 10 guest does not have any audio driver (Linux guests are fine though) AND attempting passthrough of usb device gives an "access denied" error. So no webcam capabilities and even if I could there would be no way to hear ppl. Basically I want to use my Windows guest for work and school and thereby (with Firjail+apparmor) sandbox any mandatory weirdness from Zoom and Microsoft Teams and Google Meet. For some reason I need to use all of those for work or school and only Zoom works sandboxed on my system. I'm running Manjaro/xfce.

Set up my first GPU passthrough gaming VM using virt-manager a few days ago, the performance is so close to native it's awesome! Definitely going to game and record videos on it from now on. I do miss Virtual Box's simple folder sharing feature for sharing from Linux to Windows, using Samba and wsdd as an alternative is cool too just not as simple, but that was really the only let down and the extra performance of KVM makes up for it. Also for some reason if I reboot the VM, the GPU passthrough silently fails, so I have to force shut the VM off and start it again and make sure to never restart within Windows. But that's no big deal. It's probably just an issue with my hardware; it's quite old.

[@quaasar1247]

Thanks for great tutorial!

[@user-pb1xd8pv2l]

Mental Outlaw, I gotta say. You really exhibit this "use X until I use Y" pattern. I specifically recall a video where you talked about QEMU/KVM being too complicated/whatever and that everyone should just use virtual box. Meanwhile... The landscape hasn't changed since that video was made. The only thing that changed was you've tooled around with it more and decided that Virtualbox belongs in the bin now that you aren't using it. Thank God you found virt-manager, otherwise you'd still be telling everybody to use Virtualbox. I guess we all really do learn in the end. This constantly ADHD aspect of open source users is the most annoying thing in the world of computing. Why don't you tell all your followers to install Ubuntu? They'd have KVM/QEMU working out of the box with ZFS and full disk encryption! Can't you make a video tutorial on how to do that with Gentoo? I'm joking of course. That's way too much for ANYONE besides full time basement dwellers. I recently switched from Linux and Windows to chromeOS and macOS. I'm back to living life and no longer pretending to fight a lost war

[@spaghettiking653]

I agreed with all your points, but... switching to chromeOS and macOS? How is that an improvement? You go out of your way to chain yourself down to a proprietary platform that happily pilfers your data via telemetry, imposes barriers to accessing and modifying your own machine, and is effectively a dumbed-down, layman-proof version of Linux in the first place. I understand switching to Windows if that's what you prefer, or you need software to run, but willingly switching to a less permissive os, because using Linux Mint/Ubuntu is a "lost war"? Precisely that kind of indifference threatens freedom! Using a foss operating system is not about measuring each other's techno penises in a frenzied elitism contest, it's about placing the power over the system in the hands of the consumer, not the power over the consumer in those of the system.

[@user-pb1xd8pv2l]

@@spaghettiking653 so you want to talk about telemetry and security? Do you run an AMD64 CPU? Apple's M1 chip doesn't have remote access capabilities as confirmed by Marcan, the guy who ported Linux to Apple Silicon. As far as chrome and apple spying, what does that mean when you're preemptively pwned by Intel and others at the negative ring level? I don't need Tor because I'm not a political dissident nor a human trafficker etc, and none of you last war fighters are going to stop internet regulation and control crackdowns. Governments do as governments will, and you think that your tiny puny opinion that most people don't even have the technological prerequisite understandings to even OPINE is going to matter to a large enough populace to actually reach public outcry levels? No way, man. macOS is way less likely to be hacked than a poorly implemented custom encryption deployment blindly following some Arch wiki guide with zero understanding. And also way less likely to be hacked than Windows as well. And chromeOS also has way better default security parameters than most Linux distributions. That's also a fact. Linux sucks for desktop use in my experience. chromeOS is way better on an old laptop than ubuntu is. But that's just my opinion. macOS is more enjoyable to me than Windows because it doesn't have 3 different control panel generations existing simultaneously. I'm not cucked enough to use iOS, however. So I'm sure we agree on a lot. Also the Mac doesn't pilfer my data because it's a workstation not connected to the web and the Chromebook is used for regular research... Not sure what's wrong with that approach. You're not modifying your machine. You're probably not even recompiling your kernel or using a custom init. You're running stock firmware and a regular bios. Who the hell are you to talk about modifying your own machine? OKAY, Terry davis 2.0. Let's hear about your custom shit. Built with other people's Legos. Unless you really are Terry 2.0. You open source fanatics are constantly talking about hypotheticals and conspiracy theories and almost all of it is only an issue if you want to always leave your machine connected to the internet. You all really just sound like CSAM consumers tbh, lmao. Like, having your computer online all the time so you can constantly be browsing -- that's another optional addiction but you people gaslight productive individuals who don't worry about security with nonsense about your NON-EXISTENT cyber security. Some of us visit libraries and use our computers for computations. And Chromebooks are for web browsing and that's it. Again, What's wrong with that approach? Don't you dare talk about your power as a consumer. You're running a proprietary CPU with multiple remote access backdoors ffs. And you're telling me I'm using the wrong browser/OS.

[@user-pb1xd8pv2l]

Not to mention Linux is a wholly corporate venture and that's exactly why you have "Nvidia, FUCK YOU" attitude. You beg the corporations you openly hate for better support. Lol.

[@spaghettiking653]

@@user-pb1xd8pv2l Not much I can do about my proprietary CPU, and as far as I'm aware, there's very little alternative in the way of open hardware to begin with. Sure, I could go out of my way to get an M1, but then wrangle with the process of removing macOS - nothing inherently wrong with it, of course, no one's gonna tell you you can't use your own hardware and software however you like. There is nothing wrong with your approach. But macOS sure as shit ain't to my liking, and for the same reason I wasn't able to purchase an AMD chip in distaste of Intel's pride and anticonsumerism, I feel that using any other chipset, on top of running Linux, will make an unbearable amount of software simply unrunnable, as far too much of it is architecture- and chipset-dependent. And for the record, I have built my own kernel, though not for the purposes of watching CSAM, but just to patch out the shitload of bloatware that ships with a generalised kernel. Even still, that kernel is dramatically less bloated than Windows, for chromeOS and macOS I cannot say; at any rate, the point is not that you need Julian Assange level system knowledge to modify your own system, I'm just saying it allows you more leverage over its appearance, function, etc. because it isn't maintained by a corporation that wants to impose its one-size-fits-all approach onto all users. More power to you if you want to use those operating systems, but I don't consider my use of Linux to be a "losing war", to be honest. The difference so far has been basically negligible; I'm just using my computer without blessing several multi-billion dollar corporations with the benefaction of my precious, precious data. Specifically, Google and Microsoft. What goes on on the hardware level is beyond my control and financial capabilities; I ain't gonna shell out another several hundred just to "free" myself from one proprietary hurdle into another. It's not like governments will listen, but I still think it's possible to at least show corporations their place: you can already see the effect on Facebook stock when Apple implements a "do not track" button, and consciousness about privacy is growing tremendously as it is anyway. With regard to security, I don't see how there's particularly much difference between a default Linux installation and a Mac one, considering neither is especially prone to mainstream malware, which primarily targets Windows a priori to capitalise on its colossal userbase. If any system is more likely to be hacked, it's the one which is closed-source, shut off for inspection by the audit of the public, allowing absolutely no one to augment its security with a simple open-source patch. Only hackers can benefit from closed-source, as they only have to contend with the proprietor's security team, not the entire FOSS public. For desktop use, I'd imagine Mac, Linux, ChromeOS, etc. to be all the same, no? Why should one be dramatically more secure than another? On the whole though, I do agree we probably think the same on many points. Pleasure to talk to someone with an actually meaningful and critical opinion.
