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

- 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.
