Subject: [PATCH] qemuMigrationCookieAddNBD: Fix filling of 'capacity' when
blockdev is used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With -blockdev we must look up via the nodename rather than the 'drive'
alias which is not present any more.
This fixes the pre-creation of storage volumes on migration with
non-shared storage.
