2012-10-17block-migration: Switch meaning of return valueJuan Quintela1-5/+9
Make consistent the result of blk_mig_save_dirty_block() and mig_save_device_dirty() Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-17block-migration: make flush_blks() return errorsJuan Quintela1-14/+8
This means we don't need to pass through qemu_file to get the errors. Adjust all callers. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-17buffered_file: buffered_put_buffer() don't need to set last_errorJuan Quintela1-2/+0

2012-10-17savevm: Only qemu_fflush() can generate errorsJuan Quintela1-17/+18
Move the error check to the beggining of the callers. Once this is fixed qemu_file_set_if_error() is not used anymore, so remove it. Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>

2012-10-17migration: Add dirty_pages_rate to query migrate outputJuan Quintela5-2/+31

2012-10-17Separate migration bitmapJuan Quintela3-31/+43
This patch creates a migration bitmap, which is periodically kept in sync with the qemu bitmap. A separate copy of the dirty bitmap for the migration limits the amount of concurrent access to the qemu bitmap from iothread and migration thread (which requires taking the big lock). We use the qemu bitmap type. We have to "undo" the dirty_pages counting optimization on the general dirty bitmap and do the counting optimization with the migration local bitmap.
