Subject: [PATCH] KVM: nVMX: Report 2MB EPT pages as supported
Date: Wed, 23 Oct 2013 14:40:31 +0100	[thread overview]
Message-ID: <5267D1CF.5000501@siemens.com> (raw)

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.
