Bug Description
Hi,
this might be the worst bug report ever, but there just isn't a lot more info available when the issue occurs.
I tried to set up 2nd level KVM on a P9 machine with kvm_pr but I run into (this is the series on commands I used on P8 btw):
$ sudo modprobe kvm_pr
modprobe: ERROR: could not insert 'kvm_pr': Input/output error
Unfortunately there is no dmesg message (not even with level set to debug) or anything like it, so I'm stuck asking if P9 does not work with kvm_pr at all or if there are other constraints one should know?
Note: while no more a problem for kvm_hv on P9 I disabled SMT but the issue persists.
Modinfo LGTM and matches the kernel:

It feels more that I'm missing something than a bug, but in that case I have to ask what it is.
