Description Cole Robinson 2013-12-18 21:16:09 UTC
Description of problem:
Start a qemu-system-ppc64 guest with spice. I have TLS spice ticketing enabled on this machine.

Since x86 guests don't complain, I assume there's already an selinux rule for them that allows this read access, but it should be extended to all qemu-system-* binaries since spice theoretically works for all of them.
SELinux is preventing /usr/bin/qemu-system-ppc64 from 'read' accesses on the lnk_file /etc/pki/libvirt-spice/ca-cert.pem.

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

If you believe that qemu-system-ppc64 should be allowed read access on the ca-cert.pem lnk_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 qemu-system-ppc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

1707ae5d67632014c7b565610c8127c44e60dd35 fixes this in git.

Please back port to RHEL 7 also.
