A look at the templates would be more helpful. But here is what i infer, ComputePPC64LE role uses virtual-guest tuned profile, but it also tries to apply _TUNED_CORES_ (IsolCpusList) and fails. For virtual-guest profile, IsolCpusList parameter is not required. If this parameter is moved a role-specific as like KernelArgs (only for the role which has cpu-parititioning profile), the issue should have been fixed. To confirm the issue, a look at the templates would be helpful.
