QEMU

“You can just use QEMU. It has RVA23 support and is probably still faster and easier than using actual machines.”

“the surface area of kvm and qemu is still very large and difficult to reason about”

“it's bizarre to try and escape QEMU given how many times it has been done”

“Having ability to spin up virtual machines speeds up development quite a bit.”

“It's been invaluable to get the same development and testing tools on both platforms”

“You'll get best compatibility for 20+ year Windows gaming using either”

“QEMU is also a good option for Windows software that won't run on Wine.”

“it's unmatched for batch uses, like as something part of a distro build chain”

“It is portable so you run it on other OSes which is handy when everything is under the same desktop app.”

“Architecture emulation with qemu-userspace is 5-10x slower than running a native build.”

“Upstream or bust, it's really not that hard, it just takes a little persistence”

“QEMU has worse performance than Apple's native virtualization framework on macOS”

“I currently use QMEU with qcow2 images to achieve this, works well enough.”

“It allows the VM to only write changes to disk which saves time and space”

“their device drivers may rely on some hardware behavior of the peripherals that is not implemented in QEMU”

“QEMU is extremely good at running modern operating systems, and not so much at older ones”

“There's not a whole lot of interest in making Windows 9x run well on QEMU.”

“qemu will allow you to expose the keyboard, mouse, and framebuffer as a VNC server”

“Windows in QEMU with PCI passthrough to the SCSI controller might have better chances to work.”

“trying to keep up with seemingly arbitrary changes to the command-line options format over time”

“Watching qemu build a thing for 10 minutes that I know should build in 45 seconds is painful.”

“I find running different-endian software in QEMU really annoying and difficult.”

“QEMU userspace emulation is usually the easiest for most "normal" programs IMO.”

“I think nowadays the only safe and sane way is running Windows isolated as a VM (e.g. QEMU on proxmox”

“QEMU doesn't always make clear when you're running emulated or virtualized.”

“I prefer to have software running in QEMU as that tend to be much more install-and-forget”

“Companies have made billions of dollars on top of Fabrice Bellard's works, qemu, ffmpeg etc.”

“I did manage to convince some of them to run it in qemu, but it's difficult.”

“for some of my tests I did forward accesses to QEMU itself (And worked wonders”

“It's a bit like bash, you might like it or not but decades later it's still there, on most devices.”

“Qemu can run SPARC binaries and emulate a full SPARC system enough to run Solaris 2.6”

“bellard is basically proof that the "10x engineer" exists. ffmpeg, qemu, quickjs”

“so many people use FFmpeg and QEMU suggest that he is quite good at documenting”

“Fabrice Bellard is widely considered one of the most productive and versatile programmers alive”

“I did have limited success with QEMU, but I never got it working quite right.”

“switching between the 386 and 486 with -cpu flag gives the user clear results”

“QEMU is also nice because you can just trash the disk images to get a clean start.”

“Nonpersistent vm-based browser, I use qemu + cage + firefox and some glue logic to fire up a copy of a base image which gets…”

“qemu which is slow but plenty good for running some code where this matters”

“makes it really simply to run podman/docker containers with images for other architectures”
