I am getting errors in the compile when I do the "pip install”. I have attached the output from pip. I looked at the code and I do not see anything obvious)
When I do a yum install of python-libguestds.x86_64 the python interface works correctly.

Any help or suggestions would be appreciated.
I think what is happening is that you've got an older version of libguestfs installed than the one you're building the python bindings for. Because libguestfs (eg. git) contains its own python bindings, the assumption has always been that the version of libguestfs will be exactly the same (ie. all APIs will be present and identical). If you build different versions, then that's no longer true, so you see errors from "missing" APIs (ie. ones not present in your old version of libguestfs). eg: build/temp.linux-x86_64-2.7/guestfs-py.o guestfs-py.c:310:26: warning: ‘struct guestfs_btrfsbalance’ declared inside parameter list [enabled by default] put_btrfsbalance (struct guestfs_btrfsbalance *btrfsbalance) ^ This could be fixed, but needs patching in generator/python.ml upstream.
