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.

+++ This bug was initially created as a clone of Bug #1245323 +++

SELinux is preventing spice-vdagent from 'getattr' accesses on the chr_file /dev/vport1p2.

Steps to reproduce:
1. Install Fedora-Live-Workstation-x86_64-23-20150717.iso via virt-manager
2. Boot the qemu-kvm guest
3. Open the appropriate utility in order to look for SELinux' warnings

Comment 1 Pavel Grunt 2016-03-11 18:33:54 UTC 
It happens in RHEL7.3 so cloning, it blocks spice-vdagent from running in gdm - bug 1271267

SELinux is preventing /usr/bin/spice-vdagent from getattr access on the chr_file /dev/vport1p2.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that spice-vdagent should be allowed getattr access on the vport1p2 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep spice-vdagent /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
