That said there's no real alternative available at the moment. well one alternitive to nova providing local lvm storage is to use the cinder lvm driver but install it on all compute nodes then use the cidner InstanceLocalityFilter to ensure the volume is alocated form the host the vm is on. https://docs.openstack.org/cinder/latest/configuration/block- storage/scheduler-filters.html#instancelocalityfilter on drawback to this is that if the if the vm is moved i think you would need to also migrate the cinder volume seperatly afterwards.
I wasn't aware of the InstanceLocalityFilter, so thank you for mentioning it! Eric
