Hi Avi, Marcelo, here is a patch-set that implements a shadow-vmcb for nested SVM. The shadow-vmcb is always used when the L2-guest is invoked. This saves some memory copys in the nested vmrun and vmexit paths because the contents of the host-vmcb do not need to be saved/restored anymore. This patch-set also prepares nested-svm for the emulation of clean-bits.
