[ovirt-users] ovirt homeserver

Hi, I'm building a homeserver to run ovirt and wanted to get opinions on the best approach. The server will be used as a test/studybed for ovirt/kvm/vcloud/openstack/ceph. The server will be based around a Xeon E5 10 core with 128GB ram. Option 1: Build server with CentOS 7.2 and deploy ovirt directly on top. Option 2: Build server with CentOS 7.2 and deploy multiple ovirt instances on top of KVM. Which will be the most stable versatile method? If a GPU is used as a passthrough device can it be used on several vm's or is it restricted to 1 vm? If 2 GPU's are used can 1 be used as a dedicated passthrough to 1 vm and the other shared between the remaining vm's? Is CentOS/RH the best platform for ovirt? Is it okay/advisable to load the latest kernel, (4.8 ish), on to CentOS before installing ovirt? Any and all comments/advice welcome, David
