[Kimchi-devel] [PATCH 2/2] Use ppc64_cpu values to retrieve max vcpu value

[Jose Ricardo Ziviani]

  - libvirt is not returning a right number for the maximum vcpus
    possible in PowerKVM. If such value is used, the VM refuses to boot
    complaining the value is greater than the machine type limit. However
    the limit can be retrieved from ppc64_cpu, which is the number of
    cores available * the number of threads per core.
