摘要:
Embodiments herein pre-load memory translations used to perform virtual to physical memory translations in a computing system that switches between virtual machines (VMs). Before a processor switches from executing the current VM to the new VM, a hypervisor may retrieve previously saved memory translations for the new VM and load them into cache or main memory. Thus, when the new VM begins to execute, the corresponding memory translations are in cache rather than in storage. Thus, when these memory translations are needed to perform virtual to physical address translations, the processor does not have to wait to pull the memory translations for slow storage devices (e.g., a hard disk drive).
