Hi Mark, Just to add to this - if you use XenServer as the underlying hypervisor then yes, it can perform automatic resize of the partitions when you resize an instance between two flavors. I believe you need to set auto_disk_config=True for the instance - at which point the expectation is that you have a single partition and are using EXT3 or EXT4. See https://github.com/openstack/nova/blob/master/nova/virt/xenapi/vm_utils.py#L798 for the technical details. This occurs when you issue the nova command to resize an instance between the flavors and requires you to be running XenServer with the EXT3 SR type - see http://docs.openstack.org/trunk/openstack-compute/admin/content/introduction-to-xen.html for more details on setting up XenServer.
