Did you force an update of statistics after the migration? Also, what are the initial size and growth settings for TempDB?

And why on this good green Earth would you stick with the SQL Server 80 compatibility?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

You should also be sure your VM has resources. A database server VM is not like some other file server, print server, etc. VM. This needs more resources, more minimums, with fewer guests on the main host.
