On linux s390x, we usually run in virtualized environments (LPAR and/or z/VM / KVM ).
It is helpful for instance in support cases to get some information about the virtualized environment in the hs_error file .
A lot of info can be taken from the /proc/sysinfo file on linux s390x .
Example information added to hs_error file :
