Libaums QEMU setup

README.md

Steps

• Install qemu-system-x86_64

• Download Android-x86 RPM from https://www.fosshub.com/Android-x86.html

• Extract the RPM (I'm using rpmextract from Arch, GitHub)

• cd into the android-[version] directory from the RPM

• Create a backing image for the USB drive:

  • qemu-img create -f raw USB.img 4G

• Use my adapted QEMU launcher script

• Once it's booted up, you can use adb connect localhost:5555 to install and test the app

I always get "failed to connect", but with telnet I can see that the port is open. Any step I might be missing?

Okay, connection to "VirtWIfi" did the trick!

Great! Let me know if you manage to make some progress :)

By the way, you can use this to pass through a real USB device (replace the emulated USB lines):

-device nec-usb-xhci,id=xhci -device usb-host,bus=xhci.0,hostbus=2,hostaddr=2

Of course replace hostbus, hostaddr with the USB device values, and chown the drive in /dev/bus/usb.
