Query: Memory virtualization in virtualized systems: segmentation is better
  than paging   The utilization of paging for virtual machine (VM) memory management is the
root cause of memory virtualization overhead. This paper shows that paging is
not necessary in the hypervisor. In fact, memory fragmentation, which explains
paging utilization, is not an issue in virtualized datacenters thanks to VM
memory demand patterns. Our solution Compromis, a novel Memory Management Unit,
uses direct segment for VM memory management combined with paging for VM's
processes. The paper presents a systematic methodology for implementing
Compromis in the hardware, the hypervisor and the datacenter scheduler.
Evaluation results show that Compromis outperforms the two popular memory
virtualization solutions: shadow paging and Extended Page Table by up to 30%
and 370% respectively.
