When will we get a replacement for QEMU? It's a bloated security mess and the cause of most virt CVEs. KVM is a pretty good hypervisor but we need device emulators.

Google wrote a replacement for Google Cloud but they aren't releasing it.

just fork qemu and fix it or write your own x86 emulator / kvm hyper-visor that should be super easy
Nolan Baker
QEMU is fine for CPU emulation, that's not used with KVM/virtualization. QEMU is used with KVM for peripheral emulation. (disk, network, VGA, PCI, USB, serial/parallel ports, etc.)
KVM is actually good code and has a relatively small codebase. KVM is fuzzed and audited by many companies and is fairly secure.
Jason Powell
I really hope we do see a replacement, and hopefully that replacement is more intuitive and simple. Maybe i'm just a brainlet, but I can never figure out QEMU's options and the logic behind how you do things, and I just end up going back to Virtualbox.
Christian Stewart
Amazon AWS is moving to KVM soon. Is this the death of XEN?
Jack Thomas
Use it with libvirt.
If you need a GUI, use virt-manager. Gnome Boxes is also an option but it's too simple (like most gnome shit).
Colton Diaz
Never knew about this
Thanks!

Wow, Virgil 3D finally made it into the kernel: virgil3d.github.io
is the performace decent?
Logan Gonzalez
If you're using QEMU, just do GPU passthrough and get 99% gaming performance. Virgil doesn't even have windows guest drivers.
Brandon White
It's called Qubes
Justin Mitchell
it's not enabled by default. you have to compile qemu with the option enabled and then play a bunch of games to get it going.
i could give a shit about 3d acceleration or 3d in general inside a vm, I just want 2d acceleration so the interface is snappy, which is never going to happen. I haven't gotten virgil3d setup with qemu yet, I want to try. virgil3d is supposed to use the host gpu to some extent to accelerate 3d, and mesa uses 3d now to accelerate 2d with DRI if i understand it right. So in theory, running a browser or moving a window around the screen won't look like a slideshow inside of the VM, but I'm not getting my hopes up.
gpu passthrough is really the best answer.
Luke Campbell
This is why we need AGPL.
Parker Cox
QXL+Spice looks decent to me.
Dominic Cruz
it works and it's useable, i'm not really complaining, but it's nothing compared to how silky smooth it is running natively with everything accelerated. firefox and chromium have gpu accelerated 2d now too if you turn it on. if you could get that going in a vm you wouldn't even be able to tell your in one.

Even 3D support for X11 guests in Virtualbox is in a dilemma.
Dylan Foster
Why not use joyent.com
Gavin Brooks
Now that we are on the topic of qemu, is there any way of having it run properly (with a hypervisor like kvm) on Windows or can Virtualbox use qcow2 images? I don't want to use virtualbox on Linux, but I want windows ppl to be able to use my images.
Landon Nelson
the real (((delimma))) is oracle's support for open source
extremetech.com
there's a quote somewhere of the ceo saying something along the lines of "our customers tried open source, and they prefer proprietary" referring to virtual box but i can't seem to find it.
Isaac Davis
That seems like a valid stance for a free open source project with limited developer resources, however I'd like to know what they're directing their attention to instead of 3D support, what else do they deem as more important and what are they actually working on besides 3D? Without that information it just seems like they're saying "we're not going to work on it." not "we would work on it if we didn't also have to work on this first".
This is obviously just an anecdote but I will say that I know a good handful of people, myself included, who have switched from virtualbox to other products (usually vmware), I don't know any that went the other way.
Jayden Hill
Use qemu-img to convert qcow2 to another format
Dominic Smith
Too bad gnome-shell is an opengl compositor and wouldn't benefit from 2d acceleration. one of the most popular desktop environments is all llvmpipe
software opengl rendering. No benefits from 2d acceleration whatsoever.
Isaiah Thompson
it doesn't seem like they're working on a whole lot of anything. I can't think of the last update to virtualbox that was significant. they probably pump more work into the open source but seperately licensed extensions for usb 3 and shit like that.
i can't really argue for the corporate side, where's the money for oracle to dump a bunch of resources into virtualbox.
David Edwards
i thought mesa accelerates 2d with 3d anyway.
Angel Ramirez
LLVMpipe is a fallback driver for software rendering OpenGL 3d applications on your CPU instead of GPU.
Zachary Gutierrez
this would be good then, i don't use gnome-shell i use xfce, but since there's zero interest in hardware accelerated 2d in VM's, if it all runs in 3d, and some VM somewhere get's it together with hardware accelerated 3d, like virgil3d, then it might happen.

I'd rather spend a billion hours implementing vdi support in qemu or qcow2 in virtualbox.
Noah Sanchez
vdi is supported in qemu
Lincoln Wright
Why the fuck do the server people even care about extra libraries? It's not like they are running processes.
Austin Perez
tracking all that user data takes a lot of space
Elijah Wright
all for a simple simple arm virtualization
qemu-system-arm.exe -M versatilepb -cpu arm1176 -m 192 -hda Occidentalis_v02.img -kernel kernel-qemu -append "root=/dev/sda2" -net nic -net user,hostfwd=tcp::2222-:22,hostfwd=tcp::5800-:5800,hostfwd=tcp::5900-:5900
Parker James
this is why virt-manager exists, and it's meant to be scripted obviously nobody is typing that shit out everytime
David White
I've never understood the point of doing this? Why not just dual boot windows?
And Nvidia has been do doing shady shit. If they detect your are using KVM, the drivers refuse to run. QEMU had to add an option to hide the KVM signature: lists.gnu.org
Wyatt Turner
In other news, it looks like Virtual Box modules will soon been in the Linux tree. It's currently being worked on in staging,
No more DKMS bullshit :D
Angel James
lol oracle

Why is Redhat helping upstream VirtualBox drivers? It's a direct competitor.
Samuel Perez
if it's in the kernel it's not a competitor anymore

Wow, now I can finally play SuperTuxKart in QEMU!
Noah Gomez
I've never seen a Linux user using QEMU for desktop virtualization. It's always either Virtualbox or VMWare. Is QEMU really that shitty? And doesn't Virtualbox use KVM in linux anyway?
Elijah Thompson
The documentation and intuitiveness are really that bad. I can't speak on performance, but apparently the performance with KVM is excellent though.
Cameron Gonzalez
i use qemu exclusively. i've never had any problems. the performance is near native cpu wise, with virtualbox you take a 20% performance hit, even using KVM mode. look up the benchmarks. there's also way more options with qemu, it's just not that intuitive to use. i just use virt-manager, but if it's not implemented in virt-manager you have to edit some xml for the vm directly. you can send any pci or usb device through to the VM, your tpm if you want to use that botnet, your rng, you can do all kinds of shit.
the only benefit to virtualbox is the seamless mode, which is kind of like X11 forwarding without X11 forwarding, it just makes it fullscreen but only draws the windows your using. there's no seamless mode with qemu/virt-manager, which uses's spice or vnc, so i just do X11 forwarding when I want that.
Connor Garcia
Running QEMU through virt-manager / libvirt is better anyway
libvirt does automatic SELinux / Apparmor confinement, runs QEMU as a unprivileged user, drops unneeded capabilities, etc.
