Hi Junyi, We need a test to verify the data is really random, it might catch this bug. eg: generate a lot of numbers from 1 ~ 100, then check the distribution Or using some software to verify it. Amos Fix included in qemu-kvm-1.5.3-20.el7 Verified on qemu-kvm-rhev-1.5.3-31.el7.x86_64: read 100 characters, it's random.
