From d0a073a186e4a81ae81435bd5b7286b657a69bfd Mon Sep 17 00:00:00 2001 From: Dominik Dingel Date: Thu, 12 Mar 2015 13:53:49 +0100 Subject: kvm: encapsulate HAS_DEVICE for vm attrs More and more virtual machine specifics between kvm and qemu will be transferred with vm attributes. So we encapsulate the common logic in a generic function. Additionally we need only to check during initialization if kvm supports virtual machine attributes.
