Quote: software VMM performs better than hardware VMM due to high VMM/guest transition costs and a rigid programming model; software VMM replaces traps with callouts [»adamK10_2006]

Quote: faster system virtualization with nested paging hardware; 2-d page walk for guest page table management [»bharR3_2008] Quote: use a hardware-walked, nested page table for VMMs; translates guest virtual addresses to host physical addresses; fast guest context switches and slightly slower TLB misses [»adamK10_2006]
Quote: implement a software virtual machine with binary input, code translation on execute to user-mode instructions, dynamic adjustments [»adamK10_2006] Quote: VMM translates guest instructions to short, basic block, code fragments; chain fragments together in the translation cache
