[Libvir] Still can't run a simple python test libvirt !
Hi, I am still unable to run my simple libvirt test! I checked out the code from libvirt cvs and following the instructions till 'make install'. It all went well. So then I ran my simply python test, as shown here (http://www.libvirt.org/python.html). It keeps on giving me the following error. [root@lcgctb9 libvirt]# python testLibvirt.py Traceback (most recent call last): File "testLibvirt.py", line 1, in ? import virt ImportError: No module named virt I have verified that the library is linked by the following: [root@lcgctb9 libvirt]# pkg-config libvirt --libs -L/usr/local/lib -lvirt -lxenstore [root@lcgctb9 libvirt]# pkg-config --variable=prefix libvirt /usr/local I really appreciate your help!

The python modiule is called 'libvirt' not 'virt'.
I have verified that the library is linked by the following:
[root@lcgctb9 libvirt]# pkg-config libvirt --libs -L/usr/local/lib -lvirt -lxenstore
[root@lcgctb9 libvirt]# pkg-config --variable=prefix libvirt /usr/local
Since you installed into /usr/local, I suspect you'll need to also set PYTHONPATH environment variable to tell python to look there for modules it loads. eg export PYTHONPATH=/usr/local/lib/python2.4/site-packages Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|
Thank you Daniel! So setting up the PYTHONPATH variable did the trick! Although the simple test executes, but with an interesting error complaining about an undefined symbol in libvirtmod.so [root@lcgctb9 libvirt]# python testLibvirt.py Traceback (most recent call last): File "testLibvirt.py", line 1, in ? import libvirt File "/usr/local/lib/python2.3/site-packages/libvirt.py", line 7, in ? import libvirtmod ImportError: /usr/local/lib/python2.3/site-packages/libvirtmod.so: undefined symbol: PyEval_ThreadsInitialized Regards Omer On 12/19/06, Daniel P.

Hmm, you're using ancient Python 2.3 there. The PyEval_ThreadsInitialized function which we use to make threading work in libvirt was new in Python 2.4, so looks like you're out of luck trying to use Python 2.3 Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|
Aha.. I thought so :-) Ok.. I will try to deploy this with later Python versions (2.5) perhaps! Thanks ! Omer On 12/19/06, Daniel P. Berrange <berrange@redhat.com> wrote:
