So, do I understand it right - I can't get rid of additional layer for cinder volumes, if I want to use local storage?

The XenServer Nova integration supports BFV and volume attach for Cinder volumes presented over iSCSI, so however those are managed by Cinder is independent of how XenServer can consume them. Even when using the deprecated XenAPINFSDriver, the storage had to be remote storage (i.e. provided to the host through an NFS server) so that does not let you use the hypervisor-local storage as block storage provisionable by Cinder and you would have needed a separate VM if you actually need your Cinder volumes to be provisioned from local storage.

We are currently making an installation of XS6.5+OS Juno (maybe we'll switch to kilo) We have 2 servers, controller has glance, nova and keystone, and compute vms have only nova-compute installed. We use local storage on each server, not shared one (this is important) We want to implement cinder service to manage volumes easily, but i can't understand how can we do it.XenAPINFSDriver is deprecated and isn't supported any more. The only solution i found so far is to create storage VM, give it some space and use this space for cinder volumes, and then mount it in VMs as ISCSI targets. And in the same time nova uses xenAPI to create and manage volumes when it creates instances. And what i want to make is to make cinder use Xenserver volumes both when nova creates VM and when i create volume with cinder. Without second level of abstraction. Can you tell me what are the best practices to use cinder for Xenservers with local storage? Regards, Ivan Derbenev
