Add feature: Migration of BdrvDirtyBitmap.file field.Bitmap 'percistancy' can be migrated only if its(bitmap) storage disk has id and the destination qemu has disk with same id.
Stefan Hajnoczi wrote:
Code might be necessary to ensure that: 1. The source host does not store the bitmap after successful live migration handover. (It could overwrite new data with old data!) 2. The destination host does not discard an "in_use" bitmap when it opens the qcow2 file before migration handover.
