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?
Thanks,
Milan
