QEMU

(Quick EMUlator) Open source software for creating emulation and virtual machine environments, developed by Fabrice Bellard. As an emulator, it is used to run operating systems and applications written for another hardware platform; for example, running ARM software on an x86-based PC.

For virtualization, QEMU is used to emulate devices and certain privileged instructions and requires either the KQEMU or KVM kernel modules and the host operating system to provide a virtual machine environment. It is typically used to run Windows and DOS applications on x86-based Linux computers. For more information, visit http://bellard.org/qemu. See KVM and virtual machine.

The hardware platform used was composed from an AMD Phenom II X6, 6 cores, 8GB RAM, RAID0 configured hard-disks running KVM as hypervisor and QEMU as a hypervisor interface, an Intel DualCore, 4GB RAM as the storage layer and an AMD C-60 DualCore, 4GB RAM as the management layer.
QEMU (quick emulator) is a hosted hypervisor that performs hardware virtualization, which can be used to provide virtual hosting of several virtual computers on a single computer.
It uses a fuse mount point for volume management (create/delete/snapshot,rollback,...) but Qemu accesses the virtual disk images directly to get best performance.
