[Users] Questions about Ovirt flexibility

Hello, I have in my server lab several machines: - with debian or ubuntu - without virtualization extensions. So I ask: - is the ovirt agent (not the manager) installable on debian/ubuntu/gentoo? - is the agent compatible with rhev? - can ovirt manager use rhev agent? - can ovirt use servers without virtualization extensions but with QEMU installed? Thanks in advance for any reply! Mario
