From d3134dbf2046076b6e52b05890e812442d5257fb Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 23 Oct 2013 14:40:31 +0100 Subject: [PATCH] KVM: nVMX: Report 2MB EPT pages as supported As long as the hardware provides us 2MB EPT pages, we can also expose them to the guest because our shadow EPT code already supports this feature.
