Retest:
Version of components:
qemu-kvm-rhev-2.1.2-8.el7.x86_64
steps and command line the same as comment 0. Don't hit this issue any more.
After step 3, qemu-kvm, guest and host are all work well.
Verify:
Version of components:
qemu-kvm-rhev-2.1.2-20.el7.x86_64

steps and command line the same as comment 0. After step 3, qemu-kvm, guest and host are all work well.
