Well, I have been reading system directory and the fact of starting the page
area in cyl. 0 doesn't seem to be the cause of this problem. Originally the
system-defined system page area is defined as: 

USER $PAGE$   NOLOG                              
 MDISK A03 3390 000 END 520PAG R                 
 MDISK A04 3390 000 END 520PG1 R        <-- This is the one we added later,
the one causing the problem.         
*                                                 

So, as you can see, the system-default defined one also starts in cyl. 0. 

                *** z/VM INSTALLATION DASD FORMAT/RESTORE ***

Could it be here the difference ?    
HCPINI8392I INSTIIS EXEC ENDED SUCCESSFULLY       
Ready;                                            

The difference must reside in that 1-3338 must have been performed at alloc
time (at z/VM installation time) instead of 0-3338 which is what we have
(erroneously ?) done.

So, we're going to define a new page device equally directory-defined as
520PAG (that is, 0-END), then we're going to CPFMTXA FORMAT it and then
ALLOCATE 1-3338 this time. 

If this problem still persists (we have formatted the disk and allocated it
exactly like 520PAG, so same definition should imply same functioning) we
better search for a new job, like Bill Gates. 

Do you agree with this plan ?

I tried them all again: PAGE, SPOL, TDSK is protected:

             it would overlap system temporary disk space.
 Ready KRIS at VMKBCT01 (01152); T=0.01/0.01 08:33:38

So the problem is probably caused by that the page area was never
properly formatted.
