The same API also works for Fedora, RHEL, Debian and Ubuntu guests, where it lists installed packages instead of “applications”.

Hi, Mr. Rich
I found a problem when I use the libguestfs:
In my project, I share a vmdk file with the ntfs file system in a container through the qemu-nbd server. I want to access it in the form of guestfish -a nbd://ip in another container based on the ARM-64 environment. /dev/sdx can be mounted successfully. When I call inspect_os, the shell throws a Hivex error. The logs are as follows:
PE32+ executable (console) x86-64, for MS Windows

libguestfs: error: inspect_os: internal error: inspect_os: unhandled exception thrown: Hivex.Error
I have installed the Hivex software package. After the problem cannot be located, I attempt to compile Hivex manually. After I run make, the following error occurs:
make[2]: Entering directory ‘/root/hivex-1.3.17/images’
CC mklarge-mklarge.o
CCLD mklarge
cmp -s ./minimal ./minimal || \
cp ./minimal ./minimal

make[1]: Leaving directory ‘/root/hivex-1.3.17’
make: *** [Makefile:1309: all] Error 2
I don’t know how to fix this mistake. What’s your opinion about this situation? Look forward to your reply.
Thanks,

After I run the guestfish_run command, the log is as follows:

But I can still list the file systems and mount /dev/sdx.
Look forward to your reply.
Thanks,
Yuxing
