Hi all, I wanna add a new block storage driver by Libvirt/Qemu way for Openstack, which is as same as Sheepdog driver for Openstack. So i think the theories are like this. 1, In the Openstack Nova branch, Openstck driver call libvirt client and send parameters to libvirt client.(From this point, i should modify Openstack Nova source codes. They are a, nova/nova/virt/libvirt/driver.py add new driver way b, /OpenStack/nova/nova/tests/test_libvirt.py add new driver test) 2, According to own protocol, libvirt client in Openstack Nova branch send parameters to Libvirt server.(From this point, i should modify libvirt library to let libvirt library support this new driver like Sheepdog). 3, Libvirt server call Qemu interfaces to send parameters to Qemu.(From this point, i should modify Qemu source codes to let Qemu support this new driver like Sheepdog). 4, In Openstack Cinder branch, Openstack driver use Qemu commands to create this new volumes to Qemu.(From this point, i should modify Openstack Cinder branch source codes like this. a, Add new driver file /OpenStack/cinder/cinder/volume/drivers/new_driver.py like Sheepdog.py b, Change file /OpenStack/cinder/cinder/tests/test_drivers_compatibility.py to test new driver). 5, At last, i should also modify /OpenStack/manuals/doc/src/docbkx/openstack-compute-admin/tables/hypervisors-nova-conf.xml to configure this new driver. Are my theories right? Should i do any other stuffs? Could anyone give me any other suggestions? Thanks in advance ;-) -- Thanks Harry Wei -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
