Management of virtual machines (VMs) on a large scale remains a
significant challenge today. We lack general and vendor-independent
quantitative criteria/metrics by which to describe the state of
infrastructures for virtualization. This data is essential to both
expressing administrative policy goals and to measure ongoing
compliance with them in production settings.
In this work, we consider VM management in production
environments. We investigate VM applicability to real-world scientific
computing problems by comparing application performance in a
controlled environment of physical servers with the Manage Large
Networks (MLN) tool's implementation of the same scenario on virtual
machines. Based on our observations, we propose three new metrics by
which to describe and analyze the infrastructure in order to
incorporate virtual machine management closer into policy. The metrics
have been implemented into the latest release of our MLN tool for
virtual machine management.
