Thanks for the pointer! I've built kernels in the past but forgive me for such a stupid question. You're building this on your pc not your phone right? I keep getting this error on Arch.

Code:

Makefile:625: arch/aarm64/Makefile: No such file or directory

However I can build doing "make ARCH=arm64".

Click to expand...

The make file can't find your kernel sources

Is looking at /usr/src/linux-headers-xxxx but not found arch/aarch64/Makefile

Been asking for this also, I don't know if I am building the Kernel right.

Head if it is not too much trouble can you show use what you did to build the kernel?

I can list the commands I ran.

git clone https://github.com/torvalds/linux
cd linux
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
make defconfig
make -j8

Hi,

Is this the kernel you used: ubuntu-20.04-server-cloudimg-arm64-root.tar.xz

If so How do I complie this? Its not a source code

This is not the kernel, this is the disk image with root filesystem.
I'm sorry that I am not able to provide the commands of making the disk image, since they are provided by my mentor.
Without the consent of my mentor, I can't provide the commands.

I can roughly describe the steps.

First, create an raw disk image with qemu-img.
Next, use mkfs.ext4 to create a filesystem in the image you make with qemu-img.
After you make an ext4 filesystem, mount it and extract ubuntu-20.04-server-cloudimg-arm64-root.tar.xz under the directory that you mount the disk image.
You may have to do a little more work, like:
disable could init: https://gist.github.com/zoilomora/f862f76335f5f53644a1b8e55fe98320 (see the prevent start section)
disable root password login: Under the directory you mount the image, change the first line of etc/passwd to this: ***root::0:0:root:/root:/bin/bash***.
Finally, unmount the directory.

You just make a disk image that can be used with the following command.

/apex/com.android.virt/bin/crosvm run --protected-vm -p 'root=/dev/vda' --rwdisk ${my_disk_image} ${my_kernel_image}
