Cut the pancetta into medium dices.
Fry in a frying pan until crisp. Drain on paper towels, and set aside.
Cook the linguine al dente and drain.
Heat the butter with the garlic and pancetta in a large skillet. Add the 1 1/2 cups hot heavy cream and heat through. Season with salt and pepper to taste.
Remove from heat. Combine the egg yolks with the 1/2 cup cream and mix well. Add to the skillet.
Combine the sauce with the linguine. Toss well to cover the pasta. Add Parmesan cheese and serve at once.
