As you suggested in the in-line mail I have found a machine which supports EPT technology in our lab environment. And to maintain a homogeneous KVM Host environment used qemu-kvm packages which comes with the default repo.The thing is that by default qemu-kvm is not supporting q35 machine type .This is the reason earlier we went for Cent OS packages so that qemu-kvm can support  q35 chipset for Guest VM. Can you suggest me on the same , if i wanted to perform with RHEL 7.6 how can i proceed.
