Subject: [PATCH] qemuMigrationCookieAddNBD: Fix filling of 'capacity' when
|
|
|
a41c76 |
blockdev is used

With -blockdev we must look up via the nodename rather than the 'drive'
|
|
|
a41c76 |
alias which is not present any more.
|
|
|
a41c76 |
|
|
|
a41c76 |
This fixes the pre-creation of storage volumes on migration with
|
|
|
a41c76 |
non-shared storage.
