From 1ef2a5abcdacf3274e4ed17c612835ae10cb34d8 Mon Sep 17 00:00:00 2001 From: Nikolas Hermanns Date: Fri, 4 Mar 2016 10:01:22 +0100 Subject: Make number of cpus configurable in dha file Some compones of openstack produce a lot of CPU load. With this commit it is possible to make more use of the Hypervisor where the virtual nodes runs on.
