Subject: [PATCH 0/7] Implement Shadow VMCB for Nested SVM
Date: Wed, 13 Jul 2011 17:32:18 +0200	[thread overview]
Message-ID: <1310571145-28930-1-git-send-email-joerg.roedel@amd.com> (raw)

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.

Regards,

	Joerg
