Subject: [PATCH] spice migration: add QEVENT_SPICE_MIGRATE_COMPLETED
|
|
|
|
When migrating, libvirt queries the migration status, and upon migration
|
|
completions, it closes the migration src. On the other hand, when
|
|
migration is completed, spice transfers data from the src to destination
|
|
via the client. This data is required for keeping the spice session
|
|
after migration, without suffering from data loss and inconsistencies.
|
|
In order to allow this data transfer, we add QEVENT for signaling
|
|
libvirt that spice migration has completed, and libvirt needs to wait
|
|
for this event before quitting the src process.
