Description Gu Nini 2016-02-18 10:29:35 UTC

Description of problem:
The error prompt 'bps/iops/max total values and read/write values cannot be used at the same time' is incorrect with 'max' included.

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1. Start a guest with io throttling parameters bps(iops) and the corresponding read/write ones bps_rd/bps_wr(iops_rd/iops_wr) at the same time, take following qemu cmd line as an example:

# /usr/libexec/qemu-kvm -name rhel6.8 -enable-kvm -m 4G -smp 4 -uuid ae361e8d-288b-4e70-8783-bda0d450ce35 -nodefconfig --nodefaults -boot order=cd,menu=on -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pci.0,addr=03 -drive id=drive_image1,if=none,cache=none,snapshot=off,aio=native,format=qcow2,file=/home/iothrottling_nfsc/rhel6.8 -device scsi-hd,id=image1,drive=drive_image1,bootindex=0 -drive file=/home/kvm_autotest_root/iso/linux/RHEL6.8-Server-x86_64.iso,media=cdrom,id=cdrom,if=none -device ide-drive,drive=cdrom,bootindex=1 -vnc 0.0.0.0:10 -vga cirrus -monitor stdio -qmp tcp:0:4444,server,nowait -netdev tap,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:52:5a:30:2e:58,bus=pci.0,addr=0x7 -drive id=drive_image2,if=none,cache=none,snapshot=off,aio=native,format=qcow2,file=/home/iothrottling_nfsc/hd1,bps=1024000,bps_rd=1024000 -device scsi-hd,id=image2,drive=drive_image2
qemu-kvm: -drive id=drive_image2,if=none,cache=none,snapshot=off,aio=native,format=qcow2,file=/home/iothrottling_nfsc/hd1,bps=1024000,bps_rd=1024000: bps/iops/max total values and read/write values cannot be used at the same time

2. The error prompt is incorrect with 'max' as above


Actual results:
The error prompt 'bps/iops/max total values and read/write values cannot be used at the same time' is with 'max'

Expected results:
Max should not be included since RHEL6 don't support FOO_max.

Yes, the impact is low enough for WONTFIX.
