Hypervisor-based process protection is a novel approach that provides isolated execution environments for applications running on untrusted commodity operating systems. It is based on off-the-shelf hardware and trusted hypervisors while it meets the requirement of security and trust for many cloud computing models, especially third-party data centers and a multi-tenant public cloud, in which sensitive...
Live migration of virtual machine (VM) is a desirable feature for distributed computing such as grid computing and recent cloud computing by facilitating fault tolerance, load balance, and hardware maintenance. Virtual machine monitor (VMM) enforced process protection is a newly advocated approach to provide a trustworthy execution environment for processes running on commodity operating systems.While...
There has recently been increasing interests in using system virtualization to improve the dependability of HPC cluster systems. However, it is not cost-free and may come with some performance degradation, uncertain QoS and loss of functionalities. Meanwhile, many virtualization-enabled features such as online maintenance and fault tolerance do not require virtualization being always on. This paper...
