Fix included in qemu-kvm-rhev-2.10.0-20.el7
Comment 9 Guo, Zhiyi 2018-02-12 02:39:40 EST 
Test against qemu-kvm-rhev-2.10.0-19.el7.x86_64:
# /usr/libexec/qemu-kvm -device virtio-vga,iommu_platform=on
VNC server running on ::1:5900

Verify this issue against qemu-kvm-rhev-2.10.0-20.el7.x86_64:
# /usr/libexec/qemu-kvm -device virtio-vga,iommu_platform=on
qemu-kvm: -device virtio-vga,iommu_platform=on: virtio-gpu does not support vIOMMU yet
