Correct, RHEL-ALT would be for baremetal on Power9 systems, including 
support of KVM..

Correct, on Power9 platforms that support PowerVM, you can run the classic 
RHEL in a VM in Power8 compat mode
and likely on those PowerVM systems, RHEL classic is the better way to go 
especially given the support lifecycle 

Userspace is the same between the corresponding RHEL, and RHEL-ALT 
releases..
