From bab246db1dbb37fe55fb84c95ad086f550f443a5 Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Tue, 22 Mar 2016 23:33:40 -0400 Subject: [PATCH] block/vpc: use current_size field for XenConverter VHD images XenConverter VHD images are another VHD image where current_size is different from the CHS values in the the format header.
