Hi, Mr. Rich.
I am sorry that I left too little information in the last email because I edited with my mobile phone.
I wrote about my first question in the following link.
https://rwmj.wordpress.com/2010/11/15/libguestfs-inspection-now-lists-windows-apps/


2nd. Question
After I call the mount_local() function in guestfs.py to operate on a disk, I hope to umount it. After calling the umount_local() function, the program hangs in the foreground and no log is displayed after that. At the same time, _check_not_closed() did not throw an exception.

I'm looking forward for your reply.
Thanks,
yuxing.

There's not really enough information here to help.  What you
should do is enable debugging:

https://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs

That will produce a lot of output which can help us to narrow down the
problem.

Note that sometimes hivex will throw a real error because of some real
problem with the Windows guest.

Need a bit more information here as well.  Is there a small reproducer
of this problem?

Rich.
