Method: Beaker::OpenStack#provision_storage

Defined in:
lib/beaker/hypervisor/openstack.rb

#provision_storage(host, vm) ⇒ Object

Create and attach dynamic volumes

Creates an array of volumes and attaches them to the current host. The host bus type is determined by the image type, so by default devices appear as /dev/vdb, /dev/vdc etc. Setting the glance properties hw_disk_bus=scsi, hw_scsi_model=virtio-scsi will present them as /dev/sdb, /dev/sdc (or 2:0:0:1, 2:0:0:2 in SCSI addresses)
