You're doing quite well.  This is likely an actual bug in the
libguestfs test suite, since we always run it with mdadm available.

Before we go on, does this command succeed?

  make quickcheck

FUSE should be optional.

No.  See this diagram:

http://libguestfs.org/guestfs.3.html#architecture

The guest is not running, and does not need to run guestfsd.

Pino ^^ This is a libguestfs bug isn't it?  But may be happening
because Lirong is using Ubuntu 12.04 or the old libguestfs 1.28.1
version?

Lirong: Could you share some information about what your program does?
I'm guessing it calls guestfs_inspect_os() ?
