Hello List, 1) I've seen some slides, back in 08, in which it is described that the use of VPID, will solve the problem of TLB flush after each VM_EXIT. But, i see from the code that it actually does a flush after a VM_EXIT. Obviously, i am wrong. So I need some help, Where to look, i mean which lines of code, in order to figure out, what is happening with TLB flush and VM_EXITS 2) system call from ing 0 (non-root), to ring 0(root) Could guest os, do a system call to host os? 3) what is the mechanism of virtual interrupt injection What is the mechanism that is used for a virtual interrupt injection, in full virtualization? Host injects an interrupt to guest, HOW? eg. hardware interrupt? to which point of guest? guest complete_bh? 4) I've seen from bibliography, that KVM operates in protection ring -1. What doe it mean? Is there HW implementation for that ring? Why not in ring 0?
