Bottom-up harmonisation of management attributes describing hypervisors and virtual machines

Abstract

Abstract-The advent of host virtualization has increased the number of management attribute classes and instances. At the same time an additional degree of heterogeneity has been introduced, due to different hypervisor products coupled with multiple guest operating systems. These changes obviate provisionary methods of harmonising management information. We analyse the problem dimensions of attribute harmonisation according to a common management scenario and show why heterogeneity at hypervisor and VM level is difficult to deal with at present. In response, we present a classification of bottomup attribute matching patterns and propose a methodology for the systematic processing of management attributes. As a proof-of-concept, we describe our implementation of an attribute normalising framework extending the libvirt library.

Host-Based Virtual Networks Management in Cloud Datacenters

“…Some of the current models reflect on this matter only superficially. Only recently has this need been acknowledged, indirectly in [15]. More specifically, the authors address the problem introduced in management operations given the use of different hypervisor types in the infrastructure.…”

Docker Management Using Libvirt Api

“…VMs as the clouds core virtualization construct have been improved successively by addressing scheduling, packaging, and resource access (security) problems. VM instances acting as guests use large, isolated files on their hosts to store their entire file system and typically run a single, large process on the host[2] [3]. Although security concerns are usually addressed through isolation, several limitations remain.…”

“…To support extensibility over a wide variety of hypervisors, libvirt implements a driver-based architecture, which allows a common API to service a large number of underlying hypervisors in a common fashion [3]. This means that certain specialized functionality of some hypervisors is not visible through the API.…”

A Survey of Models for Computer Networks Management

“…Hypervisor technologies incorporate several operational specifics than what can be abstracted by available models [112,114]. Only recently has the need of modeling the hypervisor been, indirectly, acknowledged, in [113]. …”
