v41 v42 5 5 As virtualization becomes more and more prevalent, we can overcome these limitations in the virtual world. All the applications are running in the VM, so now it’s possible to implement the whole-system replication in an easy and efficient way — by saving the copy of the whole VM running on the system. As VMs are totally hardware-independent, the cost is much lower compared to the hardware expenses in traditional HA solutions. Besides, virtualization technology can facilitate the management of multiple VMs on a single physical machine. With virtual machine monitors (VMM), the service applications are separated from physical machines, thus provides increased flexibility and improved performance. 6 6 7 HAVEN means "'''H'''igh '''A'''vailability in '''V'''irtualized '''E'''nvironment with '''N'''etwork ing". It consists of several finished and ongoing projects which aim on addressing the availability and reliability challenges in virtualized system. HAVEN focus on providing transparent and comprehensive high availability (HA) to solo and multiple virtual machines (VM) running on [http://xen.org/ The Xen Hypervisor]. Most projects under HAVEN are based on Xen 3.4 VMM but they can easily be ported to more recent releases of Xen. HAVEN does not require any modification to the application and operating system (guest OS) inside the VMs, therefore although HAVEN is developed based on Xen, the ideas in HAVEN also benefit other VMMs with full virtualization.7 HAVEN means "'''H'''igh '''A'''vailability in '''V'''irtualized '''E'''nvironment with '''N'''etwork".
