Subject: [PATCH] Details: When using cirros images, of any flavor, e.g. tiny,
 the root filesystem in the image is far smaller than the flavor creates.  As
 such, the dd write silently fails and the time results are incorrectly brief.
  The resize2fs corrects the root volume size and we get more accurate
 results.
