Dan,
Thanks, that's helpful too.
So I try "systemd-detect-virt" on a zLinux and get only get "zvm", which is
a start but not too helpful.
What I'm learning is that /proc/sysinfo (and thus STSI) is arguably a
treasure trove of information, because (along with vmcp) can determine the
hierarchy of hardware and hipervisors as such:
└── systems
├── CEC:0FF28
│ ├── LPAR:VM23
│ │ └── zVM:VM23
│ │ ├── SSIcluster:none
│ │ ├── devices
│ │ ├── virtualMachine:LNXADM32
I'm hoping dmidecode will provide the equivalent on Lintel.
