Hi Cedric, Sorry for the late reply, I am on vacation this week, will try to look at this, but reply might be late.

No, I ran the qemu functional tests, and few boot tests with different options. The functional test already attaches a e1000e device, somehow that didn't trigger the same error that you saw (maybe the kernel used doesn't have support for that device). Will add a test to try petitboot kexec scenario also, so we don't hit these kind of issues in future. Regarding KVM guest, iirc we can't start KVM guest for PowerNV yet right ? About the error, seems xive2 always expecting powernv10 chip, I will have to rethink how should I use the same xive2 for powernv11.
