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the product is no longer active in Red Hat Bugzilla.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.
Description of problem:
The guest was hang when stopped the cgconfig service
Version-Release number of selected component (if applicable):
libvirt-0.10.2-1.el6.x86_64
qemu-kvm-0.12.1.2-2.316.el6.x86_64
kernel-2.6.32-309.el6.x86_64
How reproducible:
100%
1 prepare the domain xml
# cat lxc.xml
<domain type='lxc'>
<name>toy</name>

<console type='pty'>

</domain>
2 Define and start lxc guest.
# virsh -c lxc:/// define lxc.xml
# virsh -c lxc:/// start toy
# virsh -c lxc:/// list --all
Id Name State
----------------------------------------------------
24294 toy running
3 Unmount cgroup
# /etc/init.d/cgconfig stop
# /etc/init.d/cgconfig status
Stopped
# lscgroup
4 Then destoy the guest and found that the guest was hang
# virsh -c lxc:/// destroy toy
5 Restart the libvirtd service and found that the guest was in "shut off" state
# /etc/init.d/libvirtd restart
# virsh -c lxc:/// list --all
Id Name State
----------------------------------------------------
- toy shut off
Actual results:
The guest was hang when stopped the cgconfig service ,besides the guest was shutoff when restart the libvirtd service
Expected results:
the guest shouldn't be hang when stopped the cgconfig service and the guest should be still in "running"states when restart the libvirtd service
Additional info
IIUC, it looks like virsh destroy actually destroy the domain (in which case it's just ok to see the domain shut off after restarting libvirtd) but hung in a followup cleanup phase. Could you provide libvirtd debug logs?
