How to use this with qemu ?

[beppe9000]

I would like to accelerate an aosp iso for android x86

QEMU patch is not ready yet. Adding support to QEMU is not a priority here. However, I do have a patched QEMU. I can share with you if you like. But it is not tested much.

[beppe9000]

That's fine. I can try it a little.

[Taogle2018]

OK. Let me share with you.
But please do remember the QEMU is NOT a google supported work as this Android Emulator Hypervisor Driver. It is a work in my spare time and more for people who want to play with QEMU for fun. :)

• Download and install msys2

• Start C:\msys64\mingw64.exe

• Updates (then close window and restart mingw64.exe): pacman -Syu

• Updates: pacman -Su

• Install basic packets: pacman -S base-devel mingw-w64-x86_64-toolchain git python

• Install QEMU specific packets: pacman -S mingw-w64-x86_64-glib2 mingw-w64-x86_64-gtk3 mingw-w64-x86_64-SDL2

• Get QEMU sources:

git clone git://github.com/qemu-gvm/qemu-gvm.git
cd qemu-gvm
git submodule update --init ui/keycodemapdb
git submodule update --init capstone
git submodule update --init dtc

• Build QEMU:

./configure --enable-gtk --enable-sdl --target-list=x86_64-softmmu --disable-werror --disable-capstone
make
Run in qemu/x86_64-softmmu ./qemu-system-x86_64 -L ./../pc-bios -accel gvm

Thanks I will try!

Let me close this issue. I am waiting for beppe9000's feedback. Now at least I know thesword53 can run the patched QEMU.

[beppe9000]

I was unable to compile because of some msys errors... during package install (i had to add --needed to install base-devel), configure (unrecognized host os) and make (error 1, asking to do configure). I'm still waiting to try on another machine. It's a bit difficult right now with covid but I iwll eventually do it.

This is the one I built yesterday.

[beppe9000]

Thanks, I tried like this and got here. Maybe my problem is that I'm not running android-x86 correctly, since I get no video after selecting the boot option.

It just stays like this, with a blinking cursor...

[Taogle2018]

It is the bios problem. Use this https://1drv.ms/u/s!AljlID0ntVyugehD4wb1psbX8_DCGA?e=67sBkM
and replace the same file in qemu-gvm-bin and try again.

[Taogle2018]

Or you can save the old one and rename to something else, in case you will need later to boot Windows 7 or 10. The old one is a UEFI bios. @thesword53 told me how bios matters. If you keep both, you are able to use "-bios xxxxx" to the command line.

[beppe9000]

Ok, I tried replacing the file and making a backup of the old one. Now I get a kernel panic... which is better than no output. 🤷

@beppe9000 Download the file OVMF_CODE.fd and add "-bios /path/to/OVMF_CODE.fd" to command line.

I was able to boot android-x86_64-9.0-r1.iso on my Ryzen 2700 and Intel i9. I would like to help but it seems I can not reproduce it. Actually I was able to run 9.0-r2 and 14.1 as well.
Perhaps your AMD FX CPU makes difference here? Did you ever try to run the livecd directly on the hardware?

[beppe9000]

add "-bios /path/to/OVMF_CODE.fd" to command line.

i tried this but it keeps rebooting after selecting the livecd option

i am going to try booting that iso from a usb key to check it for sure
