Thanks a lot for hints. Barton, and others, I will redifine storage areas to get xstore. I can add more 2 or 3 3390-3 page volumes. Today there is only one volume for page and one for spool. Please keep in mind, that this is a no production z10 installed in our data center just for POC tests, so I can change definitions very very fast. I will do changes next monday and return here with results. Thanks again and Happy Easter for all!!!

Is this a brand new VM install right out of the box? If so, then this is most likely to be the problem. 48G of real, plus the default paging areas in a brand new VM install add up to just about 52G or so, depending on whether you used mod 3 or mod 9s. It works for MAINT because CMS is extremely memory efficient; it doesn’t require that every page in the virtual machine definition be actually present when it IPLs, and it touches only what it actually needs. Linux touches every page at some point, so you need enough paging space to support the total size of all the virtual machines you define, plus a little bit of insurance. Add at least 3-4 mod 9 or mod 27s as paging space and see if the problem goes away.
