Not exactly: the SQL-Server 2005 licensing is per socket but each virtual
installation count as more (and separate) sockets; the exact number of
sockets to be counted for each VM beeing dependant on the number of
available virtual sockets inside that VM. For a more detailed explanation,
you should read the following documents:

If you still have questions after that, I would suggest that you call
1-800-426-9400 in the US or your regional Microsoft office in other
countries to get an official answer from MS.
