TLDR
Fast Virtual Disk is a new virtual machine (VM) image format and the corresponding block device driver developed for QEMU that enables instant VM creation and instant VM migration, even if the VM image is stored on direct-attached storage.Abstract:
Fast Virtual Disk (FVD) is a new virtual machine (VM) image format and the corresponding block device driver developed for QEMU. QEMU does I/O emulation for multiple hypervisors, including KVM, Xen-HVM, and VirtualBox. FVD is a holistic solution for both Cloud and non-Cloud environments. Its feature set includes flexible configurability, storage thin provisioning without a host file system, compact image, internal snapshot, encryption, copy-on-write, copy-on-read, and adaptive prefetching. The last two features enable instant VM creation and instant VM migration, even if the VM image is stored on direct-attached storage. As its name indicates, FVD is fast. Experiments show that the throughput of FVD is 249% higher than that of QCOW2 when using the Post-Mark benchmark to create files.read more

A Performance Study on the VM Startup Time in the Cloud
Ming Mao,Marty Humphrey +1 more
TL;DR: This paper studies the startup time of cloud VMs across three real-world cloud providers -- Amazon EC2, Windows Azure and Rackspace and analyzes the relationship between the VM startup time and different factors, such as time of the day, OS image size, instance type, data center location and the number of instances acquired at the same time.

VDN: Virtual machine image distribution network for cloud data centers
TL;DR: A chunk-level Virtual machine image Distribution Network (VDN) is proposed, which takes advantage of the hierarchical network topology of data centers to reduce the VM instance provisioning time and also to minimize the overhead of maintaining chunk location information.

QEMU, a fast and portable dynamic translator
TL;DR: QEMU supports full system emulation in which a complete and unmodified operating system is run in a virtual machine and Linux user mode emulation where a Linux process compiled for one target CPU can be run on another CPU.
kvm : the Linux Virtual Machine Monitor
TL;DR: The Kernel-based Virtual Machine, or kvm, is a new Linux subsystem which leverages virtualization extensions to add a virtual machine monitor (or hypervisor) capability to Linux.
PostMark: A New File System Benchmark
TL;DR: Network Appliance Filers (file server appliances) are shown to provide superior performance (via NFS or CIFS) compared to local disk alternatives, especially at higher loads.

Fast transparent migration for virtual machines
TL;DR: This is the first system that can migrate unmodified applications on unmodified mainstream Intel x86-based operating system, including Microsoft Windows, Linux, Novell NetWare and others, to provide fast, transparent application migration.
