You are correct regarding the subnet prefix (it should be the port's
current subnet prefix, and not the default subnet prefix).
Regarding the SM GUID, the version of the Virtualization Annex that I
worked with (v17 -- Feb 16, 2015) states:
SM GID A well-known GID that is associated with the SM,
comprising the concatenation of the Subnet prefix and the GUID 0x2. The
SM GID is never present in any GID Table.
Has the SM GUID value changed (0x2 -->0x0200000000000002) in the Annex
since v17? (I'm not a member of the MGTWG workgroup, so I don't have
access to the most recent version).
