Can a server in a VHP schedule hosted VMs in a communication-aware manner to enable satisfactory application performance even under conditions of high consolidation, while still adhering to the high-level resource provisioning goals in a fair manner?
The need for accurate accounting of the overheads of virtualization
In VHP, the unit of resource allocation and accounting for applications changes to VM
VMM is responsible for virtualizing I/O devices.
Can a server in a VHP account for the overheads of virtualization and incorporate them into its CPU scheduling to provide fair resource allocations?
Among the domains eligible to run within the current period (determined by SEDF fairness limits), the scheduler chooses to schedule the domain with the highest network intensity (with most number of pending network packets).
