Doc Text:
With this update, Red Hat Enterprise Linux versions less than version 6.9 are not supported in clusters using the machine type pseries-rhel7.4.0 or newer (4.1+). It is now blacklisted and cannot be started due to there being no CPU architecture available. A new definition of guest operating system for Red Hat Enterprise Linux versions 6.9 and greater has been added and should be used for Red Hat Enterprise Linux 6 guests in Red Hat Virtualization 4.1 and greater clusters. Also note that the cluster compatibility version 4.2 requires the pseries-rhel7.5.0 machine type, which is introduced by Red Hat Enterprise Linux 7.5 hosts. Until they are available you need to keep using the 4.1 cluster compatibility level.

Description Michal Skrivanek 2017-09-12 08:46:46 UTC 
This can be achieved by creating 2 OS definitions in osinfo
RHEL <=6.8 with cpu.unsupported.value of all supported CPUs (power8,power9?) in clusters 4.2+
RHEL 6.9+ without the blacklist
