++FYI
Also I could see some patches on below link:
https://www.redhat.com/archives/libguestfs/2014-August/msg00134.html
But those are not available in libguestfs-1.32.10.
PYTHON 2 bindings working perfectly and PYTHON 3 having issues.

Hi,
Looking at python 3 bindings it looks like some issue in libguestfs.
I have tried a lot and still facing "undefined Symbol" issue while importing
guestfs.
But Able to enable python 3 bindings in libguestfs but it's not working as
expected.
I could see another user faced same issue and the same has reported in below
link:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=646360
I hope libguestfs-1.32.10 also having same issue.
Please help us on this.
Regards,
Abinaya

Hi,
Have tried python2 bindings on libguestfs-1.32.10 (fresh installation).
It seems like still the log is like below:
checking for python... python
checking Python version... 2.7
checking for PYTHON... yes
checking Python prefix... /opt/python/x86_64/2.7.11-1 checking for Python
site-packages path... /opt/python/x86_64/2.7.11-1/lib/python2.7/site-packages
checking for Python extension suffix (PEP-3149)... .so checking for
PyCapsule_New in -lc... no checking for PyString_AsString in -lc... no
But python-guestfs is working fine without any issue on python 2.7.11.
[root@euca-10-254-20-192 libguestfs-1.32.10]$ ./run python
>>> import guestfs
>>> g = guestfs.GuestFS(python_return_dict=True)
>>> help(guestfs)
Help on module guestfs:
NAME
guestfs - Python bindings for libguestfs
FILE
/var/fpwork/libguestfs/SOURCES/libguestfs-1.32.10/python/guestfs.py
DESCRIPTION
import guestfs
g = guestfs.GuestFS (python_return_dict=True)
g.add_drive_opts ("guest.img", format="raw")
g.launch ()
parts = g.list_partitions ()
The guestfs module provides a Python binding to the libguestfs API
for examining and modifying virtual machine disk images.
Amongst the things this is good for: making batch configuration
changes to guests, getting disk used/free statistics (see also:
virt-df), migrating between virtualization systems (see also:
virt-p2v), performing partial backups, performing partial guest
clones, cloning guests and changing registry/UUID/hostname info, and
much else besides.
Libguestfs uses Linux kernel and qemu code, and can access any type of
guest filesystem that Linux and qemu can, including but not limited
to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
schemes, qcow, qcow2, vmdk.
Libguestfs provides ways to enumerate guest storage (eg. partitions,
LVs, what filesystem is in each LV, etc.). It can also run commands
in the context of the guest. Also you can access filesystems over
FUSE.
I have followed same steps which I tried with python 3 but here its working as
expected.
Can you suggest us for further.
Regards,
Abinaya

This is supposed to be ‘yes’ which is why it's failing. You'll have to debug
m4/guestfs_python.m4 and config.log to find out why that is but something is
obviously broken about your Python installation.
