[RFC 0/3] KVM: PPC: BE guest-exit fixes and nestedv2 vCPU limit

Posted by Ritesh Harjani (IBM) 2 weeks ago

These issues were identified while adding kvm powerpc selftests infrastructure
support [1]. Patch-1 and Patch-2 were identified while running the selftests on
Qemu+TCG+powernv+BE, while Patch-3 can also be reproduced on a real pseries LPAR
with nestedv2 capabilities.
