In BZ 1337557 we came to the conclusion that we won't support the spapr-rng device in qemu-kvm-rhev. Since the device is currently available by default due to the rebase to QEMU 2.6.0, we should now make sure that it gets disabled in the downstream version again.
Fix included in qemu-kvm-rhev-2.6.0-6.el7
Test this bug on qemu-kvm-rhev-2.6.0-7.el7.ppc64le.
# /usr/libexec/qemu-kvm -device ? 2>&1 |grep rng
name "virtio-rng-device", bus virtio-bus
name "virtio-rng-pci", bus PCI, alias "virtio-rng"
# /usr/libexec/qemu-kvm -device spapr-rng,id=rng0
qemu-kvm: -device spapr-rng,id=rng0: 'spapr-rng' is not a valid device model name
spapr-rng device has been disabled.
