Virtualization is still possible when the instruction set architecture lacks such support  but the hypervisor remains more complex and must rely on additional techniques. Despite the focus on architectural support in current architectures  some historical perspective is necessary to appropriately frame the problem. The first half of the book provides the historical perspective of the theoretical framework developed four decades ago by Popek and Goldberg. It also describes earlier systems that enabled virtualization despite the lack of architectural support in hardware. As is often the case  theory defines a necessarybut not sufficientset of features  and modern architectures are the result of the combination of the theoretical framework with insights derived from practical systems. The second half of the book describes state-of-the-art support for virtualization in both x86-64 and ARM processors. 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. It concludes with a performance comparison of virtualization on current-generation x86- and ARM-based systems across multiple hypervisors.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45276678324277,"sku":"ByrdShop_1627056939","price":335.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9781627056939.jpg?v=1780560146","url":"https:\/\/atxbooks.com\/products\/hardware-and-software-support-for-virtualization-synthesis-lectures-on-computer-architecture-38-9781627056939","provider":"ATX Books","version":"1.0","type":"link"}
