openQRM abstracts Virtualization and supports the following...
U-tube is a dynamic memory management tool for Xen virtualized envi
...It is implemented as a loadable device driver to coordinate guest OS’ MMU with underlying hypervisor. In contrast to the popular ballooning mechanism, memory hotplug can dynamically expand a guest OS’s physical memory space beyond its maximum configured at booting time.
SnowFlock enables high performance computing on virtual machine (VM)-based cloud environments. In SnowFlock, a VM transparently becomes a cluster of VMs by cloning in sub-second time into multiple copies executing on different physical hosts.
Semys consists of a library for group communication and an architecture to build a sequential consistent system. A sequential consistent process can run on several physical hosts and is not disturbed by the downtime (crash) of a host.
It is an implementation of Tuple-Space by using MPI library. Tuple-space is a logically shared memory in many parallel computing. It provides the appearance of a shared memory but do not require on underlying physical shared memory.
