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 of problem:
virsh command cpu-baseline cause memory leak.
Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux Server release 6.5 Beta
libvirt-0.10.2-22.el6.x86_64
kernel-2.6.32-412.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.394.el6.x86_64
How reproducible:
always
Steps to Reproduce:
1. make a cpu profile xml or capabilities xml.
# virsh capabilities > cap.xml
2. check memory leak for cpu-baseline
# valgrind -v --leak-check=full virsh cpu-baseline cap.xml
valgrind result:
==22406== 8 bytes in 1 blocks are definitely lost in loss record 8 of 103
==22406== at 0x4C2677B: calloc (vg_replace_malloc.c:593)

==22406== LEAK SUMMARY:
==22406== definitely lost: 8 bytes in 1 blocks
==22406== indirectly lost: 0 bytes in 0 blocks
==22406== possibly lost: 0 bytes in 0 blocks
==22406== still reachable: 139,233 bytes in 1,575 blocks
==22406== suppressed: 0 bytes in 0 blocks
Expected result:
no memory leak
