Hi, I established a mapping between virtual CPU to the physical core following this Mirantis guide [1], I went through it successfully but the problem I have is that I am only able to launch one instance regardless of the the number of vCPUs specified in the Flavor (2,4,16.....). Have you implemented this option before ?
