挂载由Android模拟器创建的qcow2映像 [英] Mount qcow2 image created by Android emulator
问题描述
我正在尝试挂载Android模拟器创建的userdata-qemu.img.qcow2文件.以下过程不起作用:
I'm trying to mount the userdata-qemu.img.qcow2 file created by the Android emulator. The following procedure does not work:
sudo qemu-nbd -c /dev/nbd0 ~/.android/avd/Pixel_C_API_27.avd/userdata-qemu.img.qcow2
第一个命令运行良好，但正在运行
First command runs well, but running
sudo qemu-nbd -c /dev/nbd0 ~/.android/avd/Pixel_C_API_27.avd/userdata-qemu.img.qcow2
结果如下:
Fehler: /dev/nbd0: unbekannte Partitionstabelle
Modell: Unbekannt (unknown)
Festplatte /dev/nbd0: 3146MB
Sektorgröße (logisch/physisch): 512B/512B
Partitionstabelle: unknown
Disk-Flags:
基本上，它无法识别图像文件中的分区表.您可能想知道
Basically it cannot recognize a partition table in the image file. You may wonder what's the output of
fdisk /dev/nbd0 -l
所以这里是:
Medium /dev/nbd0: 3 GiB, 3145728000 Bytes, 6144000 Sektoren
Einheiten: sectors von 1 * 512 = 512 Bytes
Sektorengröße (logisch/physisch): 512 Bytes / 512 Bytes
I/O Größe (minimal/optimal): 512 Bytes / 512 Bytes
如您所料，安装当然会失败，因为如果分区表本身也无法识别，则无法识别任何分区.感谢您的帮助！
As you could expect already, mounting fails of course, since no partitions can be recognized if the partition table itself cannot be recognized either. Thanks for any help!
我刚刚发现问题一定与Android的用户数据加密有关.由于我从未更改过任何密码，因此仿真器的userdata分区的加密密码必须是默认的"default_password"密码.如何解密该映像以使其能够挂载?
I've just found out that the problem must have to do with Android's userdata encryption. As I've never changed any password the encryption password of the emulator's userdata partition would have to be the default one "default_password". How can I decrypt the image to be able to mount it?
推荐答案
您可以使用以下过程安装userdata-qemu.img.qcow2
You can mount userdata-qemu.img.qcow2 using the following procedure
-
将图像转换为原始图像
convert the image to a raw image
qemu-img convert -O raw userdata-qemu.img.qcow2 udata-raw.img
使用losetup设置要安装的环回设备
use losetup to setup a loopback device for mounting
sudo losetup -f -P userdata.img
使用losetup -l查看已设置的设备
losetup -l
NAME SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE DIO
/dev/loop0 0 0 0 0 /path/to/userdata.img 0
安装驱动器
mount the drive
mkdir /tmp/mnt
sudo mount /dev/loop0 /tmp/mnt
然后ls /tmp/mnt/给出
app benchmarktest benchmarktest64 lost+found misc nativetest nativetest64
