商品描述

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. 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 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. 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.

商品描述(中文翻譯)

本書的重點在於硬體所提供的必要「架構支援」,以有效運行虛擬機器,以及相應的運行它們的「超級監視器」的設計。即使指令集架構缺乏此類支援,虛擬化仍然是可能的,但超級監視器仍然更複雜,並且必須依賴其他技術。

儘管目前的架構關注於架構支援,但一些歷史觀點是必要的,以適當地定位問題。本書的前半部分提供了四十年前由Popek和Goldberg開發的理論框架的歷史觀點。它還描述了早期系統,儘管硬體缺乏架構支援,但仍實現了虛擬化。

通常情況下,理論定義了一組必要但不充分的功能,現代架構是理論框架與從實際系統中獲得的見解相結合的結果。本書的後半部分描述了x86-64和ARM處理器中虛擬化的最新支援。本書詳細描述了這兩種處理器架構的CPU、記憶體和I/O虛擬化,以及Linux/KVM、VMware和Xen超級監視器的案例研究。最後,本書對當前一代x86和ARM系統上多個超級監視器的虛擬化性能進行了比較。
