Qemu on Windows 10 - no acceleration found

Qemu on Windows 10 - no acceleration found

Hi All,

I have tried QEMU on Windows 10 host with and without HyperV active in the
features list.
Neither seemed to affect the "really slow" speed. Either option results in
-enable-kvm giving "no acceleration found".

How do I enable acceleration on QEMU for windows.

So I tried --enable-whpx and I get Invalid option. Im on Windows 10 and
QEMU 4.2.0

I'm confused.  Then I don't know where to download the HAXM. The place I
found is GIT and it wants the user to compile it. I was looking for just an
EXE.

Thanks

Jerry

Sorry, the FAQ was outdated. I updated it now.

Run `qemu-system-x86_64 --accel whpx`.

Using WHPX is easier than using HAX.
