Michael T., All of the XIVE fixes/changes originating from myself were made in an effort to get PowerVM firmware running on PowerNV with minimal testing of OPAL firmware. However, even with those fixes, running PowerVM on PowerNV is still pretty unstable. While backporting these fixes would likely increase the stability of running PowerVM on PowerNV, I do think it could pose significant risk to the stability of running OPAL on PowerNV. With that in mind, I think it's probably best if we did not backport any of my own XIVE changes. Nick, can you respond regarding the changes you made? Thanks, Glenn
