“…In addition, specialized tools are developed to collect modeling information on Xen [26] KVM [27] and VMware. For example, Xentop [28], XenMon [29] and XenoProf [30] are designed to collect information of host and that of each VM in Xen platform, an enhanced perf [31], [32] is for KVM, and ReTrace [33] for VMware. With those tools, collecting modeling information for VM power metering is no longer a challenge for virtualized platform.…”

“…QEMU/KVM provides full virtualization environment allowing the guest to be able to run in the KVM environment without any changes. However, as for KVM I/O virtualization, the traditional way is to use the QEMU pure software way to simulate the I/O devices, and its efficiency is not very high [3]. By installing the KVM Para-virtualized drivers (Para-virtualized Drivers, PV Drivers) in the guest, it can significantly improve the performance of the guest (especially I/O performance) [4].…”

“…Its advantage is that the software can simulate a variety of hardware devices, and there is no need to modify the guest operating system [1]. But the path of the I/O operation is relatively long, so there are more VMEntry and VMExit occur requiring multiple context switching (context switch) as well as multiple data replication, and therefore its performance is poor [3].…”
