On s390x it only uses sysinfo for systemd-detect-virt,
src/basic/virt.c:306: r = get_proc_field("/proc/sysinfo", "VM00
Control Program",
WHITESPACE, &t);
but there also the Host UUID is exposed:
$ cat /proc/sysinfo
VM00 UUID: 0804001f-c45f-4345-994f-9fec048e822e
There it also seems not used to (re-)generate a machine ID consistently:
