Star Technology
Projects Centres Each VM in domain U
encapsulates one or more applications such as Star
Technology Project Centres
Web server, remote desktop, DNS, Mail, Map/Reduce, etc. We assume all
PMs share a backend storage. The multiplexing of VMs to PMs is
managed using the Star Technology Projects
Centre Usher framework Star Technology
Project Centre . The main logic of
our system is implemented as a set of plug-ins to Usher. Each node
runs Star Technologies Projects
Centres an Usher local node manager (LNM) on domain
0 which collects the usage statistics of resources for each VM on
that Star Technologies Project
Centres node. The CPU and network usage can be
calculated by Star Technologies Projects
Centre monitoring the scheduling events in Xen. The
memory usage Star Technologies Project
Centre within a VM, however, is not visible to the
Star Technology Projects
Centers hypervisor.
