Modules not loaded on VirtualBox Android x86

[ghost]

I have a Android x86_64 on VirtualBox. I patched ramdisk.img and magisk 20.3 start without issue.
I tried to install some modules as riru core, riru xposed and others but after reboot the module is not loaded. In log I can't see nothing.

Before reporting bugs you need to try Magisk Canary to ensure that the bug exists or not on the current code.
Anyway, I believe that this problem has already been solved, as you can see in this report

I installed and tried canary version (debug), same result in the list of installed modules: No modules found.

So the problem is not in the loading of the modules, it is in the installation. There is a new commit on the modules installation code, wait for the next update of the Magisk Canary to see if it solves your problem or wait for some response from topjohnwu

@KaMyKaSii sorry for wrong informations, but while the installation of modules I can't see errors on screen, so I thought the issue was on loading.
I tested the new version and continue with the same issue

I followed this guide and I convert android x86 8.1 from one partition to 3 partitions (boot, /system and /data), works only with 20.1 after update to 20.3 the previous working modules disappear.

[osm0sis]

#2594 might help. You'll have to test again after the next build with it merged.

[shakalaca]

The filesystem layout is kind of weird ..

I put the init file (inside initrd.img) here: https://gist.github.com/shakalaca/68020f29a75b816bed8245761c746f34

Looks like some of the entries in /proc/mounts came before chroot, so Magisk could not mount /system and /data partition properly and the module system failed because of that ..

[osm0sis]

Sounds like it was pure luck that it ever worked at all. Does the emulator.sh work for this use case?

[androidacy-user]

Modules never worked because the emulator.sh can't be ran on boot (excl modifying the ramdisk)

[shakalaca]

If we can do the hack on Android x86 project, I think it's better to keep the complexity there and leave Magisk clean and simple, so here's the hack : (for AVD we still need the patch #2594):
https://github.com/shakalaca/MagiskOnEmulator

@etmatrix please have a look and see if it works for you :)

[ghost]

@shakalaca thank you for you work.
The script prepare_image.sh doesn't work properly and I don't know if will never work.
mount /dev/block/sda1 return Device busy.

mount -o ro -t ext4 /dev/block/sda1 /data/local/tmp/root/
mount: '/dev/block/sda1'->'/data/local/tmp/root/': Device or resource busy

I got ramdisk.img and initrd.img with:

• power off android x86
• modprobe nbd max_part=16
• qemu-nbd -c /dev/nbd0 Android8.vdi
• mount /dev/nbd0p1 /mnt/tmp/

I think the correct script to run for vbox is patch_vbox.sh, doesn't matter, I pulled all files and executed process.sh as root, after this operation I pushed the new ramdisk.img and initrd.img and copied, but after I poweron the virtual machine, it's stuck on boot.
I debugging it, maybe the loop while true which check the directory /sbin/.magisk/

EDIT
Sorry my fault, I execute the entire process another one and now works, module are loaded on boot with magisk 20.4

I tested the script of @shakalaca and works on Android 8.1 r4 x86/x86_64, Android 9 r2 x86 (x86_64 not yet tested).

• copy ramdisk.img and initrd.img from installation disk
• clone repository https://github.com/shakalaca/MagiskOnEmulator
• download latest version of magisk's zip and rename to magisk.zip
• connect to device with adb
• adb push initrd.patch process.sh magisk.zip update-binary /data/local/tmp
• adb push ramdisk.img /data/local/tmp/ramdisk.img.gz
• adb push initrd.img /data/local/tmp/initrd.img.gz
• adb shell "sh /data/local/tmp/process.sh /data/local/tmp/"
• adb pull /data/local/tmp/ramdisk.img
• adb pull /data/local/tmp/initrd.img
• restore new ramdisk.img and initrd.img to installation disk

I think the scripts prepare and installation are not usable with android x86, but process.sh is fantastic for installation and patching of magisk on android x86

how to connect to device with adb when i type adb in cmd windows it shown

[0xD34DC0DE]

@lamjed001
You need to add adb to the PATH environment variable

[ouija]

* copy ramdisk.img and initrd.img from installation disk
* clone repository https://github.com/shakalaca/MagiskOnEmulator
* download latest version of magisk's zip and rename to magisk.zip
* connect to device with adb
* adb push initrd.patch process.sh magisk.zip update-binary /data/local/tmp
* adb push ramdisk.img /data/local/tmp/ramdisk.img.gz
* adb push initrd.img /data/local/tmp/initrd.img.gz
* adb shell "sh /data/local/tmp/process.sh /data/local/tmp/"
* adb pull /data/local/tmp/ramdisk.img
* adb pull /data/local/tmp/initrd.img
* restore new ramdisk.img and initrd.img to installation disk

This method was working up until March of 2021, here's an updated version I've used with Android-x86 and Magisk v22.0:

• Clone the repository at https://github.com/shakalaca/MagiskOnEmulator
• Copy initrd.img and ramdisk.img from Android installer to folder where you cloned repo
• Download latest copy of Magisk v22 apk and save to this same folder as "magisk.zip"
• Edit the patch.sh script and replace with:

#!/bin/sh

adb wait-for-device
adb -e push ramdisk.img /data/local/tmp/ramdisk.img.gz
adb -e push initrd.img /data/local/tmp/initrd.img.gz
adb -e push magisk.zip /data/local/tmp/magisk.zip
adb -e push busybox /data/local/tmp/
adb -e push initrd.patch /data/local/tmp/
adb -e push process.sh /data/local/tmp/
adb -e shell "dos2unix /data/local/tmp/process.sh"
adb -e shell "sh /data/local/tmp/process.sh /data/local/tmp $1"
[ -d patched ] || mkdir patched
adb -e pull /data/local/tmp/ramdisk.img ./patched/
adb -e pull /data/local/tmp/initrd.img ./patched/

-Connect to device via adb and run sh ./patch.sh
-Replace the patched initrd.img and ramdisk.img files from the ./patched folder into the Android-x86 installation folder.

Hello ouija, sorry to disturb you, I followed your steps to complete, but the module still cannot be installed, thank you for your advice.

[olbb]

Great!
I follow the step, and it worked.
Despite with the log 'Device or resource busy'
But the magisk's devices is mounted while init,
which is add via initrd.patch.

If the shell is not worked for some reason,
You may also unpack the initrc.img file as the shell do,
and change the init file with initrc.patch, repack the img.

[ugegkonst]

Hello
-Replace the patched initrd.img and ramdisk.img files from the ./patched folder into the Android-x86 installation folder.
How can i do that?
I can't do any changes because it's read only

It's on your physical disk where the android x86 installed.
You can replace the img files on other OS, e.g PE.

" > * adb push initrd.patch process.sh magisk.zip update-binary /data/local/tmp"

Someone can tell me, where i can find that "update-binary"?
by shooting this command, i get an error:
adb: error: cannot stat 'update-binary': No such file or directory

this update-binary is not found in the repository... maybe somewhere in the Android system?
someone can tell me near infos about that? Where i can find that? What is that?

and another problem is the message i get, when try:
adb shell "sh /data/local/tmp/process.sh /data/local/tmp/"
it tells me:
***** Grab magisk.zip or magisk.apk first ! *****
but magisk.zip is pushed already in the folder /data/local/tmp/

someone can advice me what im doing wrong?

I am grateful for any help..
