RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
