Subject: Revert "storageVolCreateXMLFrom: Check if backend knows how to createVol"
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=cdb757c970a42c0f3c56f6a5e2ec8c22f30c99b4;p=libvirt.git

Revert "storageVolCreateXMLFrom: Check if backend knows how to createVol"

This reverts commit 611a278fa46d3136b7fe5c6ab05e660ca3c8fdf4.

According to the original commit message, this is dead code:

  It is highly unlikely that a backend will know how to create a
  volume from a different volume (buildVolFrom) and not know how to
  create an empty volume (createVol).
