Thank you for explanation, it's clear to me now. One last question: Is there a way to get supported compatibility modes on POWER? For instance, I get the following from domcapabilities on a POWER9 machine: <cpu> <mode name='host-passthrough' supported='yes'/> <mode name='host-model' supported='yes'> <model fallback='allow'>POWER9</model> <vendor>IBM</vendor> </mode> <mode name='custom' supported='no'/> </cpu> How can I find out that POWER8 guests are also supported on the machine?
