Subject: [PATCH] qemu_migration: Use EnterMonitorAsync in
qemuDomainGetMigrationBlockers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The code is run with an async job and thus needs to make sure a nested
job is acquired before entering the monitor.
While touching the code in qemuMigrationSrcIsAllowed I also fixed the
grammar which was accidentally broken by v8.5.0-140-g2103807e33.
