*** Bug 1099277 has been marked as a duplicate of this bug. *** Fix included in qemu-kvm-1.5.3-67.el7 Reproduced with qemu-kvm-1.5.3-60.el7.x86_64.rpm. Same step as reporter.
Actual Result:

Verified pass with qemu-kvm-1.5.3-77.el7.x86_64.rpm. It complaint failure to initialize NO. of vectors greater than 128.
Actual Result:
