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:
