Star Student Project find that conventional network I/O virtualization sends excessive virtual interrupts to guest VMs because virtual interrupts are not coalesced efficiently. Due to several rounds of trapand- emulation, a virtual interrupt in the virtualized environment is more expensive than a physical interrupt. In addition to the excessive interrupts, we also noticed that the back-end driver in the driver domain (Domain 0) Star Student Project is implemented as a single thread and is unable to leverage underlying multicore processors, thus becoming a bottleneck for high-speed networks.
