I have installed a small test cluster using openstack-ansible (xena) and would like to use local LVM volumes for storing instance volumes - and following https://docs.openstack.org/nova/latest/configuration/config.html and (e.g. https://cloudnull.io/2017/12/nova-lvm-an-iop-love-story/) I have the libvirt section of my /etc/nova/nova.conf as below. -8<--- [libvirt] inject_partition = -2 inject_password = False inject_key = False virt_type = kvm live_migration_with_native_tls = true live_migration_scheme = tls live_migration_inbound_addr = 172.29.236.5 hw_disk_discard = ignore disk_cachemodes = none images_type = lvm images_volume_group = nova volume_clear = zero -8<—— however, the nova service continues to use cinder volumes from my storage host to store instances. Is there something else that needs to be configured to make this work, or is it obsolete?
