migration: support file: uri for source migration Implement support for a "file:" uri so that a migration can be initiated directly to a file from QEMU. Unlike other migration protocol backends, the 'file' protocol cannot honour non-blocking mode. POSIX file/block storage will always report ready to read/write, regardless of how slow the underlying storage will be at servicing the request. For outgoing migration this limitation is not a serious problem as the migration data transfer always happens in a dedicated thread. It may, however, result in delays in honouring a request to cancel the migration operation. Reviewed-by: Daniel P. Berrangé <berrange@redhat.com> Signed-off-by: Nikolay Borisov <nborisov@suse.com>
