Hi Greg,

How do these smaller devices allow you to manage their power state?

Typically you have a side-computer (AKA bare-metal controller) which is
always up so you can talk to it (via IPMI/Redfish/SNMP/ssh) to manage
power state of its big brother.

The pxe_ssh driver is about libvirt VMs simulating bare-metal nodes. I
am not sure this is what you need. Also, pxe_ssh driver is obsoleted by
the virtualbmc proxy by now.
