簡(jiǎn)述虛擬化技術(shù)有哪四種？

虛擬化技術(shù)有四種：服務(wù)器虛擬化、網(wǎng)絡(luò )虛擬化、存儲虛擬化和桌面虛擬化。

服務(wù)器虛擬化通過(guò)將一臺物理服務(wù)器劃分為多個(gè)虛擬服務(wù)器來(lái)提高資源利用率。

網(wǎng)絡(luò )虛擬化將物理網(wǎng)絡(luò )資源劃分為多個(gè)邏輯網(wǎng)絡(luò )，實(shí)現網(wǎng)絡(luò )資源的靈活分配和管理。

存儲虛擬化將多個(gè)物理存儲設備整合為一個(gè)虛擬存儲池，提供統一的存儲管理和分配。

桌面虛擬化將用戶(hù)的桌面環(huán)境虛擬化到服務(wù)器上，用戶(hù)可以通過(guò)終端訪(fǎng)問(wèn)虛擬桌面，提高工作效率和安全性。

簡(jiǎn)述虛擬化技術(shù)有哪四種？

什么是虛擬化？

這里簡(jiǎn)單歸納一下我的理解：

1.虛擬化是資源的一種邏輯表示，并不會(huì )受限于物理資源。

2.運行的環(huán)境不在真實(shí)的硬件上，而是硬件之上的虛擬內存中的一段，或者說(shuō)是虛擬的環(huán)境中。

3.虛擬化為數據、計算能力、存儲資源等提供了一個(gè)邏輯視圖，而不是物理視圖。

4.虛擬化的發(fā)展，大幅降低了IT硬件成本，減少了資源的浪費，并且提升了系統的穩定性和安全性。

全虛擬化

全虛擬化(FullVirtualization)也稱(chēng)為原始虛擬化技術(shù)，該模型使用虛擬機協(xié)調Guest操作系統和原始硬件，VMM在Guest操作系統和裸硬件之間用于工作協(xié)調，一些受保護指令必須由Hypervisor（虛擬機管理程序）來(lái)捕獲處理。全虛擬化的運行速度要快于硬件模擬，但是性能方面不如裸機，因為Hypervisor需要占用一些資源。

半虛擬化

半虛擬化(ParaVirtualization)是另一種類(lèi)似于全虛擬化的技術(shù)，它使用Hypervisor分享存取底層的硬件，但是它的Guest操作系統集成了虛擬化方面的代碼。該方法無(wú)需重新編譯或引起陷阱，因為操作系統自身能夠與虛擬進(jìn)程進(jìn)行很好的協(xié)作。半虛擬化需要Guest操作系統做一些修改，使Guest操作系統意識到自己是處于虛擬化環(huán)境的，但是半虛擬化提供了與原操作系統相近的性能。

虛擬化技術(shù)的關(guān)鍵特性

同質(zhì)-Equivalence

即VM的運行環(huán)境和物理機的環(huán)境在本質(zhì)上是相同的，表現上允許有一些差異。如CPU的橋片必須一致，CPUcore的個(gè)數以及內存可以不同，不必使用同類(lèi)型的網(wǎng)絡(luò )適配器驅動(dòng)等等。

高效-Efficiency

即VM的性能必須接近物理機。因此，常見(jiàn)的虛擬系統模擬器（Boches，simics等）就不能成為VM。為達此目的，軟件在虛擬系統上運行時(shí)，大多數指令要直接運行在硬件上執行，只有少量指令需要VMM的模擬或翻譯處理。

資源受控-Resourcecontrol

即VMM(VirtualMachineMonitor)對物理機的所有資源有絕對的控制力。虛擬機不允許直接執行敏感指令。
