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.

Author: Peter Krempa <pkrempa>

    security: Re-apply commit ce53382ba28179d3a504b29b4f888b6e130d53f0
    
    Recent changes in the security driver discarded changes that fixed
    labeling un-confined guests.

Moving to POST.

pkgs
# rpm -qa|grep libvirt
libvirt-0.10.1-1.el6.x86_64

steps

1. Make sure selinux is Enforcing
# getenforce
Enforcing

2. Before set security_default_confined, prepare a guest, and start it, then check the guest's seclabel

# virsh dumpxml tesredhat |grep seclabel -A 3
  <seclabel type='dynamic' model='selinux' relabel='yes'>
    <label>unconfined_u:system_r:svirt_t:s0:c317,c596</label>
    <imagelabel>unconfined_u:object_r:svirt_image_t:s0:c317,c596</imagelabel>
  </seclabel>
</domain>


3. Set security_default_confined=0 in qemu.conf and restart libvirtd

4. Recheck the guest's seclabel
# virsh dumpxml tesredhat |grep seclabel -A 3
  <seclabel type='dynamic' model='selinux' relabel='yes'>
    <label>unconfined_u:system_r:svirt_t:s0:c317,c596</label>
    <imagelabel>unconfined_u:object_r:svirt_image_t:s0:c317,c596</imagelabel>
  </seclabel>
</domain>

5. Destroy the guest, and restart it
# virsh start tesredhat
Domain tesredhat started

# virsh dumpxml tesredhat |grep seclabel -A 3
  <seclabel type='none' model='selinux'/>
</domain>

6. # ll -Z /var/lib/libvirt/images/tesredhat.img 
-rw-r-xr-x. qemu qemu system_u:object_r:virt_image_t:s0 /var/lib/libvirt/images/tesredhat.img

7.# virsh dumpxml tesredhat --inactive |grep seclabel -A 3

BTW 
I can reproduce this bug in the pkg libvirt-0.10.0-1.el6.x86_64

AS in step 5&6 ,guest can start normally
So, this is fixed.
