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the product is no longer active in Red Hat Bugzilla.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:
Set security_default_confined = 0 in qemu.conf, start guest, guest image ownership changed to qemu:qemu from root:root, but seclabel info is not output in active xml.
Version-Release number of selected component:
libvirt-2.0.0-5.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. Prepare guest image file:
# ll -Z /var/lib/libvirt/images/rhel7.2.qcow2
-rw-------. root root system_u:object_r:virt_image_t:s0 /var/lib/libvirt/images/rhel7.2.qcow2
2. Set security_default_confined = 0 in qemu.conf, restart libvirtd service
3. Check active domain xml:
# virsh dumpxml rhel7
...
<seclabel type='none' model='selinux'/>
...
No DAC seclabel info is output in dumpxml, but actually guest image file ownership is changed to qemu:qemu from root:root
# ll -Z /var/lib/libvirt/images/rhel7.2.qcow2
-rw-------. qemu qemu system_u:object_r:virt_image_t:s0 /var/lib/libvirt/images/rhel7.2.qcow2
Actual results:
As step3
Expected results:
In step 3, DAC seclabel info is output in active xml, or guest should fail to start
Additional info:
1. Keep default setting in qemu.conf
2. Prepare guest without seclabel element in domain xml
3. Start guest, check active dumpxml:
# virsh dumpxml rhel7
...
<seclabel type='dynamic' model='selinux' relabel='yes'>
<label>system_u:system_r:svirt_t:s0:c124,c389</label>
<imagelabel>system_u:object_r:svirt_image_t:s0:c124,c389</imagelabel>
</seclabel>
<seclabel type='dynamic' model='dac' relabel='yes'>
