Implementation of the KVM Hypervisor on Several Cloud Platforms: Tuning the Apache CloudStack Agent

摘要

The default KVM setup included in Open Nebula, Eucalyptus and Apache Cloud Stack could not perform well enough under certain circumstances, because it does not expose to the guest VMs some of the features included in the modern processors. In order to tune up the cloud platform for obtaining a better CPU performance for the virtualized software executed under the KVM hyper visor, we have proposed and tested an alternative KVM setup in Apache Cloud Stack. The setup provided could also be applied to other cloud platforms.
