Windows Sandbox and Windows Subsystem for Linux (WSL2) uses Hyper-V.You’ll need to remove Hyper-V completely as it will hoard VT-d’s control.Release VT-d (hardware assisted virtualizations) so HAXM can acquire it.Preparation work to get HAXM accelerator set up.So I documented the quirks to help the next poor sap who has to get qemu running on Windows 10 host efficiently over Bridged-Adapter (VirtualBox lingo) networking mode. I stupidly went down the rabbit hole and drained my time on qemu. The man page -help for the qemu’s Windows host’s VM engine was blindly copied from the Linux hosts counterpart, so it tells you about qemu-bridge-helper which is missing. There’s a few tutorials on qemu Linux hosts for moderately complex scenarios, but you are pretty much on your own trying to piece it altogether for Windows because there are some conceptual and terminology differences.
Think of them as the one who produced an ASIC (chip) and the end-user happens to be the application engineers. System integration (simplifying common use cases) is practically non-existent. There’s a company that does the clean up to make BSD (same umbrella as Linux/Unix) usable and made a lot of money: it’s called Apple Computers (since Steve Jobs’ return). The geniuses did the most sophisticated work for free but users pay time and energy cleaning after them (aka a support network dealing with daily frustrations) to make these inventions usable. RANT: Linux is not free in the sense of free beer. With the promise that Qemu might have less overhead than Hyper-V or VirtualBox (indeed it observably is), I tried installing Qemu on Windows host and it turned out to be a frustrating nightmare. Very often developers didn’t make a whole installer for it so we are often wedged between downloading a package at the mercy of its availability from package managers and their servers or compiling the damn source code! RANT: Package servers keep pulling the rug on outdated linux frustrates the hell out of me.
Turns out it doesn’t work on the latest Linux so I’d need to run an older Ubuntu just to keep it happy. I’m trying to cross compile my router’s firmware as I made a few edits override the update DDNS update frequency.
