<tt>> I've discussed this issue more today with IBM guys; and what I </tt><br>
<tt>> understood is that this Alternate version is more or less for </tt><br>
<tt>> Baremetal installations (like in Power AI HW); but when using e.g </tt><br>
<tt>> PowerVM; you should</tt><br>
<tt>> be able to go with the default RHEL with the 3.10 kernel on Power9 </tt><br>
<tt>> as well; it will just then work like RHEL 6 on Power8 (e.g will run </tt><br>
<tt>> on Power8 Compatibility mode) </tt></span><br>
<br>
<tt><span style="font-size:10.0pt">Yep.</span></tt><br>
<br>
<br>
<tt><span style="font-size:10.0pt">Both RHEL 7.5 LE for Power8 and RHEL-Alt 7.5 LE for Power9 will run fine in a Power9 PowerVM LPAR.</span></tt><br>
<br>
<tt><span style="font-size:10.0pt">The Power8 base will come up in p8compat mode - your example.</span></tt><br>
<br>
<tt><span style="font-size:10.0pt">The Power9 base will come up in P9 mode.</span></tt><br>
<br>
<br>
<br>
<tt><span style="font-size:10.0pt">Yes... the RHEL-Alt 7.5 version is *specifically* intended for Power9 bare-metal and KVM host support.</span></tt><br>
<br>
<tt><span style="font-size:10.0pt">That bare-metal support enables Nvidia Volta NVLink2 support.</span></tt><br>
