Message

Suraj Jitindar Singh Sept. 27, 2018, 6:50 a.m. UTC

This patch series adds the qemu support for running nested kvm-hv on a
POWER9 platform with appropriate hypervisor support and migration of
these guests.
That is, the ability to run kvm-hv guests as guests of an operating system
which is itself a kvm-hv guest.

The host (L0 hypervisor) and level 1 guest (L1 guest hypervisor) require
the following patch series:
[RFC PATCH 00/32] KVM: PPC: Book3S HV: Nested HV virtualization

And this patch series in the qemu instance running on the L0 hypervisor.

Patch series based on: ppc-for-3.1

RFC because waiting for the CAP number to be in upstream linux

  target/ppc: Add one reg id for ptcr
  ppc/spapr_caps: Add SPAPR_CAP_NESTED_KVM_HV
