  We study a solution of the Einstein's equations generated by a
self-gravitating, anisotropic, static, non-singular matter fluid. The resulting
Schwarzschild like solution is regular and accounts for smearing effects of
noncommutative fluctuations of the geometry. We call this solution regular
Schwarzschild spacetime. In the presence of an Anti-deSitter cosmological term,
the regularized metric offers an extension of the Hawking-Page transition into
a van der Waals-like phase diagram. Specifically the regular
Schwarzschild-Anti-deSitter geometry undergoes a first order small/large black
hole transition similar to the liquid/gas transition of a real fluid. In the
present analysis we have considered the cosmological constant as a dynamical
quantity and its variation is included in the first law of black hole
thermodynamics.
