[openstack-dev] Add Modified Compute Driver to Nova
Hi everyone I have a modified compute driver (my_driver.py and my_driver.pyc) and I copied files to /opt/stack/nova/nova/virt/libvirt/ directory. Also, nova.conf modified to use this driver (compute_driver=libvirt.my_driver.MyDriver). I can't start nova-compute with this modified driver and nova.conf. When nova-compute start , it shows this error: *2014-11-10 12:03:25.300 DEBUG nova.servicegroup.api [-] ServiceGroup driver defined as an instance of db from (pid=18709) __new__ /opt/stack/nova/nova/servicegroup/api.py:652014-11-10 12:03:25.401 INFO nova.virt.driver [-] Loading compute driver 'libvirt.my_driver.MyDriver'2014-11-10 12:03:25.406 INFO nova.openstack.common.periodic_task [-] Skipping periodic task _periodic_update_dns because its interval is negative2014-11-10 12:03:25.424 ERROR nova.virt.driver [-] Unable to load the virtualization driver2014-11-10 12:03:25.424 TRACE nova.virt.driver Traceback (most recent call last):2014-11-10 12:03:25.424 TRACE nova.virt.driver File /opt/stack/nova/nova/virt/driver.py, line 1385, in load_compute_driver2014-11-10 12:03:25.424 TRACE nova.virt.driver virtapi)2014-11-10 12:03:25.424 TRACE nova.virt.driver File /usr/local/lib/python2.7/dist-packages/oslo/utils/importutils.py, line 52, in import_object_ns2014-11-10 12:03:25.424 TRACE nova.virt.driver return import_class(import_str)(*args, **kwargs)2014-11-10 12:03:25.424 TRACE nova.virt.driver File /usr/local/lib/python2.7/dist-packages/oslo/utils/importutils.py, line 27, in import_class2014-11-10 12:03:25.424 TRACE nova.virt.driver __import__(mod_str)2014-11-10 12:03:25.424 TRACE nova.virt.driver ImportError: No module named my_driver* I really appreciate with any idea.

Re: [openstack-dev] Add Modified Compute Driver to Nova
which value did you put ? From my former experience, also check your my_driver's init function, something wrong in that function can also lead to this error, good luck Best Regards!

Not sure there is much we can do without this information.

Do you have a __init__.py in your new directory? http://www.chesnok.com/daily/2011/02/09/learning-python-the-hard-way-__init__-py-needed-for-packages-as-opposed-to-modules/ On Mon, Nov 10, 2014 at 3:43 AM, Mohammad Hosein Zarei hosein.za...@gmail.com wrote: Hi everyone I have a modified compute driver (my_driver.py and my_driver.pyc) and I copied files to /opt/stack/nova/nova/virt/libvirt/ directory.
