Subject: [PATCH] qemu: Fix crash in offline migration
|
|
|
23265d |
|
|
|
23265d |
When migrating a shutoff domain (i.e., offline migration), we have no
|
|
|
23265d |
statistics to report and thus jobInfo will be NULL in
|
|
|
23265d |
qemuMigrationFinish.
|
|
|
23265d |
|
|
|
23265d |
Broken by me in v3.10.0-183-ge8784e7868.
