[Kimchi-devel] [PATCH v2 2/2] Do not use libvirt 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.
