I do have some ideas of adding more metadata too. What sort of pieces
of info are you looking for ? Based on your previous patches, I am
assuming the various virError struct fields at the very least ? Any
others ?

I think arbitrary limits will be ok, since while the number of metadata
fields is theoretically unlimited, in practice I don't see us needing
more than say 15 fields.
