Re: [Libguestfs] python 3 bindings on libguestfs

Hello Richard, Finally found the issue. As per my understand The PyCObject API has been removed in Python 3.3. Instead of that we have to use PyCapsule, which is available in python 2.7 and 3.1+. I could see below line in python/guestfs-py.h file: #ifndef HAVE_PYCAPSULE_NEW return PyCObject_FromVoidPtrAndDesc ((void *) g, (char *) "guestfs_h", NULL); #else return PyCapsule_New ((void *) g, "guestfs_h", NULL); #endif But when run the same with python 3 this file #else part is not working as expected. So I have changed the above line as like below to work with python 3.5: #ifndef HAVE_PYCAPSULE_NEW return PyCapsule_New ((void *) g, "guestfs_h", NULL); #endif // I have removed that #else part and make it available if condition only. And now all issue fixed and able to import guestfs in python-3.5.1: [root@XXX tmp]$ python Python 3.5.1 (default, Jan 30 2018, 01:29:28) [GCC 4.4.4 20100726 (Red Hat 4.4.4-13)] on linux Type "help", "copyright", "credits" or "license" for more information. Help on module guestfs: NAME guestfs - Python bindings for libguestfs 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. Errors which happen while using the API are turned into Python RuntimeError exceptions. : Regards, Abinaya -----Original Message----- From: Richard W.M.
