[Openstack] create/attach volume in openstack

I've read somewhere that flavors (different types of VMs, like m1.tiny,
m1.small etc) have some disk space. This disk space is available as a device
like /dev/vbd. Moreover, it seems the volume attached to a VM isn't
predictable in what device it will be attached, so we need to search for
them in the VM. I think that some scripts could be placed in some packages
to do it for us.

Just what I read in my recently studies.

Regards!
