The U.S. Board on Geographic Names Gazetteer no. 57, Iceland does not list
these places.  The closest spelling, on p.225, is "Videy see Vidhey."
There is a "Vidhey" listed.  Its an island at 64 10 N  21 52 W.  There's
a marine channel called "Vidheyjarsund" adjacent to the island.  The closest
spelling to "Klaustri" is "Klaustur," which is a slope at 65 10 N  18 48 W.
The closest spelling to "Beitisto" is "Beitistahir," a farm at 64 24 N,
21 52 W.
 
Hope this helps.
