![]() ![]() This book includes an in-depth description of the CPU, memory, and I/O virtualization of these two processor architectures, as well as case studies on the Linux/KVM, VMware, and Xen hypervisors. at Stanford University and spent a year at Google working on datacenter networking. #Edouard bugnion software#The second half of the book describes state-of-the-art support for virtualization in both x86-64 and ARM processors. I am an associate professor at MIT CSAIL, where I build systems that cut across hardware and software boundaries. It also describes earlier systems that enabled virtualization despite the lack of architectural support in hardware.Īs is often the case, theory defines a necessary-but not sufficient-set of features, and modern architectures are the result of the combination of the theoretical framework with insights derived from practical systems. Hingga penghujung tahun 1998 VMware hanya diawaki oleh sekitar 20-an pegawai. Hanya berselang 6 tahun kemudian, VMware diakuisisi dan menjadi anak perusahaan dari Dell Technologies, dengan mahar 625 juta. The first half of the book provides the historical perspective of the theoretical framework developed four decades ago by Popek and Goldberg. IX: More protection Network stack in user-space unacceptable Firewall, ACL management in data plane Sending raw packets requires root Does zero-copy send require memory protection Approach: use CPU virtualization to get three-way protection between kernel, networking, and user. VMware didirikan pada tahun 1998 oleh Diane Greene, Mendel Rosenblum, Scott Devine, Ellen Wang dan Edouard Bugnion. Virtualization is still possible when the instruction set architecture lacks such support, but the hypervisor remains more complex and must rely on additional techniques.ĭespite the focus on architectural support in current architectures, some historical perspective is necessary to appropriately frame the problem. Edouard Bugnion EPFL Switzerland ABSTRACT Programming languages and systems have failed to address the security implications of the increasingly frequent use of public libraries to construct modern software. This book focuses on the core question of the necessary architectural support provided by hardware to efficiently run virtual machines, and of the corresponding design of the hypervisors that run them. Edouard Bugnion is the Professor in the School of Computer and Communication Sciences at École Polytechnique Fédérale de Lausanne. We are very grateful to our shepherd, Edouard Bugnion, and the anonymous reviewers for their valuable feedback and comments. ![]()
