Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Comment 2 Peter Krempa 2012-08-03 09:41:53 UTC 
The problem is in the RPC code that doesn't fill one of the arguments when doing the remote call. I'll post a patch soon.
Comment 3 Peter Krempa 2012-08-03 11:02:46 UTC 
Fixed upstream:

commit 2b01761d5e9addaefe33b2934576836836f486e2
Author: Peter Krempa <pkrempa>
Date:   Fri Aug 3 11:45:12 2012 +0200

    remote: Fill snapshot argument in remoteDomainSnapshotListAllChildren
    
    The remote driver did not fill the required snapshot parent argument in
    the RPC call structure that caused a client crash when trying to use
    this new API.

Moving to POST.
Comment 5 zhpeng 2012-08-23 08:07:47 UTC 
Test with: libvirt-0.10.0-0rc1.el6.x86_64

[root@zhpeng ~]# virsh snapshot-list rhel63q --descendants --from d1
 Name                 Creation Time             State
------------------------------------------------------------
 d2                   2012-08-23 15:59:00 +0800 disk-snapshot
 d3                   2012-08-23 15:59:02 +0800 disk-snapshot
 d4                   2012-08-23 15:59:04 +0800 disk-snapshot
 snap1                2012-08-23 15:59:09 +0800 running

So this is verified.
