1209394 – domstats cannot be used when do not add any option

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 Luyao Huang 2015-04-07 09:27:14 UTC

description of problem:
domstats cannot be used when do not add any option

Version-Release number of selected component (if applicable):
libvirt-1.2.14-1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:

# virsh domstats
error: An error occurred, but the cause is unknown


Actual results:
error: An error occurred, but the cause is unknown

Expected results:
fix it

Additional info:

I found there is an error in libvirtd.log:

2015-04-07 08:19:18.180+0000: 13321: error : virStorageFileBackendGlusterInit:628 : failed to initialize gluster connection to server: '/var/run/gluster/glusterd.socket': Transport endpoint is not connected

and test with this vm force:

# virsh domstats r6-qcow2
error: failed to initialize gluster connection to server: '/var/run/gluster/glusterd.socket': Transport endpoint is not connected

Comment 1 Peter Krempa 2015-04-16 07:40:52 UTC

Fixed upstream:

commit 25aa7035d373ab17eb0ba773ad521e0dbfb7449d
Author: Peter Krempa <pkrempa>
Date:   Wed Apr 15 18:14:30 2015 +0200

    qemu: bulk stats: Ignore errors from missing/inaccessible disks
    
    Rather than erroring out make the best attempt to retrieve other data if
    disks are inaccessible or missing. The failure will still be logged
    though.
    
    Since the bulk stats API is called on multiple domains an error like
    this makes the API unusable. This regression was introduced by commit
    596a13713420e01b20ce3dc3fdbe06d073682675

I can produce this bug with build libvirt-1.2.14-1.el7.x86_64

# virsh domstats
error: An error occurred, but the cause is unknown


verify this with build libvirt-1.2.17-2.el7.x86_64
