The account is where CHAP settings are derived from, volume is

One caveat here is that an existing user account must be specified
in the API call to create a new volume. We use a set algorithm to
determine account info based on passed in nova volume object. First
we check to see if the account already exists (and use it), or if it
does not already exist, we'll go ahead and create it.
For now, we're just using very basic settings, QOS is
turned off, 512 byte emulation is off etc. Will be
looking at extensions for these things later, or
this module can be hacked to suit needs.
