Subject: [PATCH 2/2] libxl: Advertise support for
 VIR_MIGRATE_CHANGE_PROTECTION
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The libxl driver has basic support for VIR_MIGRATE_CHANGE_PROTECTION
by starting and stopping modify jobs in the begin/confirm and prepare/finish
phases of migration, but it doesn't advertise that support. This can result
in unterminated jobs because the migration logic skips phases of migration
when the VIR_MIGRATE_CHANGE_PROTECTION feature is absent. Ensure jobs are
terminated properly by advertising support for VIR_MIGRATE_CHANGE_PROTECTION.
