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).

Description of problem:
If there is a running guest, When I disable creating namespace for qemu process in the qemu.conf and restart libvirtd, then destroy the guest and start the guest again. Libvirt still creates the namespace for the guest.
Version-Release number of selected component (if applicable):
libvirt-3.2.0-5.virtcov.el7.x86_64
qemu-kvm-rhev-2.9.0-5.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Start a guest:
#virsh start rhel7.3-min
2.Disable the namespace in qemu.conf
#vim /etc/libvirt/qemu.conf
namespaces = [ ]
3.Restart libvirtd service:
#systemctl restart libvirtd
4.Destroy and start the guest again:
#virsh destroy rhel7.3-min
5.Start the guest again:
#virsh start rhel7.3-min
6.libvirt still create namespace for the guest:
#lsns | grep qemu
lsns | grep -i qemu
4026532522 mnt 1 31993 qemu /usr/libexec/qemu-kvm -name guest=rhel7.3-min ...
7.Need to restart libvirtd service again after step 4 to not create namespace for the guest.
Actual results:
libvirt does not change the namespace setting for the running guest after disabe creating namespace in qemu.conf
Expected results:
libvirt should change the namespace setting for the running guest after disabe creating namespace in qemu.conf
