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
