Subject: [PATCH] qemu_migration: Use EnterMonitorAsync in
|
|
|
032100 |
qemuDomainGetMigrationBlockers

The code is run with an async job and thus needs to make sure a nested
|
|
|
032100 |
job is acquired before entering the monitor.
|
|
|
032100 |
|
|
|
032100 |
While touching the code in qemuMigrationSrcIsAllowed I also fixed the
|
|
|
032100 |
grammar which was accidentally broken by v8.5.0-140-g2103807e33.
