Subject: [PATCH] qemu_migration_params: Refactor qemuMigrationParamsReset
|
|
|
|
Because qemuMigrationParamsReset used to call qemuMigrationParamsApply
|
|
for resetting migration capabilities and parameters, it did not work
|
|
well since commit v5.1.0-83-ga1dec315c9 which only allowed capabilities
|
|
to be set from an async job. However, when reconnecting to running
|
|
domains after daemon restart we do not have an async job. Thus the
|
|
capabilities were not properly reset in case the daemon was restarted
|
|
during an ongoing migration. We need to avoid calling
|
|
qemuMigrationParamsApply to make sure both parameters and capabilities
|
|
can be reset by a normal job.
