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
