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 yalzhang@redhat.com 2016-04-28 03:53:14 UTC 
Description of problem:
No error messages for cpu-stats with --start option.

Version-Release number of selected component (if applicable):
libvirt-1.3.3-2.el7.x86_64
qemu-kvm-rhev-2.5.0-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.
# virsh cpu-stats R7.2
CPU0:
    cpu_time             9.798005025 seconds
    vcpu_time            9.364671581 seconds
CPU1:
    cpu_time             9.076250379 seconds
    vcpu_time            8.675238766 seconds
CPU2:
    cpu_time             7.054429959 seconds
    vcpu_time            6.625330794 seconds
CPU3:
    cpu_time             5.368119343 seconds
    vcpu_time            4.751755399 seconds
Total:
    cpu_time            31.296804706 seconds
    user_time            1.100000000 seconds
    system_time         13.560000000 seconds

2.
# virsh cpu-stats R7.2 --start 4

# echo $?
0

3.
# virsh cpu-stats R7.2 --start 5

# echo $?
1

Actual results:
There are no error messages if cpu-stats with the option --start larger than maximum cpu number.


Expected results:
step 2 the "echo $?" should be "1", and for step 2 and step 3, there should be error messages such as:
# virsh cpu-stats rhel62 --start 4
error: Failed to retrieve CPU statistics for domain 'rhel62'
error: invalid argument: start_cpu 4 larger than maximum of 3
