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. -Mike M On Mon, Mar 26, 2018 at 10:32 AM, Dan Horák <dho...@redhat.com> wrote: > On Mon, 26 Mar 2018 10:20:18 -0400 > Michael MacIsaac <mike99...@gmail.com> wrote: > > > Christian, > > > > Thanks, that helps.
