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 Daniel Berrangé 2012-11-22 16:53:01 UTC 
Description of problem:
When the container shuts down gracefully, the libvirt_lxc process does not quit. This wastes system resources

Version-Release number of selected component (if applicable):
0.10.2-1.el6

How reproducible:
Always

Steps to Reproduce:
1. virsh start mycontainer
2. virsh console mycontainer
3. Type 'exit' inside the container shell
4. ps axuwf | grep libvirt_lxc
  
Actual results:
libvirt_lxc process still exists

Expected results:
No libvirt_lxc process exists

Fixed upstream:
commit 37db3f5dfe713b978732a9b84982892da857813a
Author: Daniel P. Berrange <berrange>

    Fix exiting of libvirt_lxc program on container quit
    
    The virLXCControllerClientCloseHook method was mistakenly
    assuming that the private data associated with the network
    client was the virLXCControllerPtr. In fact it was just a
    dummy int, so we were derefencing a bogus struct. The
    frequent result of this was that we would never quit, because
    we tried to arm a non-existant timer.
    
    Fix the code by removing the dummy private data and just
    using the virLXCControllerPtr instance as private data
