Description of problem: Guest should failed to boot if set iops,bps to negative number Version-Release number of selected component (if applicable): qemu-kvm-rhev-0.12.1.2-2.482.el6.x86_64 kernel-2.6.32-590.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.Launch guest with: /usr/libexec/qemu-kvm -name virtio -m 1024 -cpu Westmere,check -realtime mlock=off -smp 2 -global PIIX4_PM.disable_s4=1 -global PIIX4_PM.disable_s3=1 -boot order=c,menu=on -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 -drive file=/nfs/rhel6.7_virtio.qcow2,format=qcow2,if=none,id=block-virtio,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x8,drive=block-virtio,id=block-virtio,bootindex=1 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x7 -monitor stdio -vnc :4 -vga cirrus -drive file=/nfs/test20G.qcow2,if=none,cache=none,id=drive-ide0-1-0,format=qcow2,iops=-1,bps=-1 2. 3. Actual results: qemu launched successfully and no error prompt. (qemu) info block block-virtio: removable=0 io-status=ok file=/nfs/rhel6.7_virtio.qcow2 ro=0 drv=qcow2 encrypted=0 bps=0 bps_rd=0 bps_wr=0 iops=0 iops_rd=0 iops_wr=0 drive-ide0-1-0: removable=1 locked=0 tray-open=0 file=/nfs/test20G.qcow2 ro=0 drv=qcow2 encrypted=0 bps=-9223372036854775808 bps_rd=0 bps_wr=0 iops=-9223372036854775808 iops_rd=0 iops_wr=0 Expected results: qemu prompt error like "bps and iops values must be 0 or greater" and then quit. Additional info: Tried same scenario with qemu-kvm-rhev-0.12.1.2-2.448.el6_6.3.x86_64, got expected prompt： qemu-kvm: -drive file=/nfs/test20G.qcow2,if=none,cache=none,id=drive-ide0-1-0,format=qcow2,iops=-1,bps=-1: bps and iops values must be 0 or greater Reproduced with qemu-kvm-rhev-0.12.1.2-2.477.el6.x86_64
RHEL 7.2 is okay, but not RHEV 7.2 (qemu-kvm-rhev). Please test that and clone this bug to qemu-kvm-rhev 7.3 if it's the case.

Fix included in qemu-kvm-0.12.1.2-2.486.el6
Verified with: qemu-kvm-rhev-0.12.1.2-2.486.el6.x86_64 kernel-2.6.32-584.el6.x86_64 Steps: 1.Launch guest with: /usr/libexec/qemu-kvm -drive file=/mnt/RHEL-Server-6.7-64-virtio.qcow2,if=none,cache=none,id=drive-ide0-1-0,format=qcow2,iops=-1,bps=-1 Result: qemu prompts proper info and quit: qemu-kvm: -drive file=/mnt/RHEL-Server-6.7-64-virtio.qcow2,if=none,cache=none,id=drive-ide0-1-0,format=qcow2,iops=-1,bps=-1: bps/iops/max values must be within [0, 1000000000000000]
