    libvirt: check min required qemu/kvm versions on ppc64/ppc64le
    
    This patch checks min versions of kvm & libvirt on ppc64/ppc64le
    architectures. It prevents users deploying Nova on unsupported
    hypervisor platforms with older versions of qemu/kvm.
    This check defines the min versions required to spawn instances.
    It is an extension of I2851624a8cdaf353df3386e1e3e3cc0e35af41ec.
    ppc* support was added in 2.1:

Title:
  Min qemu/kvm version check for ppc64/ppc64le

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Libvirt driver in Nova needs to add a check for min required qemu/libvirt versions on ppc64/ppc64le.
  The checks for ppc64/ppc64le are missing, so  could lead to users deploying Nova on
  unsupported hypervisor platforms with older versions of qemu/libvirt.
  QEMU/KVM is supported on multiple platforms with different levels of qemu/libvirt.

  Ref: Min versions for s390/s390x:
  https://review.openstack.org/#/c/183486

  ppc64:
  - qemu 1.6.0
  - libvirt 1.2.9

  Older versions might work, but developers indicate this is a safe min
  version for ppc64. This is equivalent to the kvm stack provided in
  Fedora 20 for ppc64.

  ppc64le:
  - qemu 2.1
  - libvirt 1.2.11

  commit da636d83dc6b1d070a705786b4daef8644eaca13 enables ppc64le in
  libvirt, which matches to 1.2.10/11

  PCI passthrough is available since qemu-2.0. However, features like
  pci hotplug, memory/cpu hotplug and pcipassthrough/srvio hotplug will
  be supported in qemu-2.4, maybe 2.5.
