and it becomes more interesting, I see the same exceptions in my F-20
guest after the migration to zEC12 and to z/VM 6.1, a RHEL-7 guest runs
in the same LPAR without problem. The difference between them is glibc -
F-20 is 2.18 based, while RHEL-7 is 2.17. Also running F-20 on zEC12 in
z/VM 5.4 is without problem. So, interesting ...
