Booting a disk image on the Android emulator

Once we have done all the changes, we can build the qcow2 image using the following command:

$ make qcow2_img USE_SQUASHFS=0
...
make_ext4fs -T -1 -S out/target/product/x86emu/root/file_contexts -L 
system -l 1342177280 -a system out/target/product/x86emu/obj/PACKAGING/systemimage_intermediates/system.img out/target/product/x86emu/system out/target/product/x86emu/system
Creating filesystem with parameters:
    Size: 1342177280
    Block size: 4096
    Blocks per group: 32768
    Inodes per group: 8192
    Inode size: 256
    Journal blocks: 5120
    Label: system
    Blocks: 327680
    Block groups: 10
    Reserved block group size: 79
Created filesystem with 2122/81920 inodes and 178910/327680 blocks
Install system fs image: out/target/product/x86emu/system.img

As we can see from the preceding command-line output, system.img will be built as usual. After that, the ramdisk image, initrd.img, will be created as follows. Pay attention to the VER environment...
