Description Jeff Layton 2016-08-22 10:35:49 UTC 
I updated my f24 machine to selinux-policy-targeted-3.13.1-191.12.fc24.noarch last night and was unable to start KVM guests afterward:

$ virsh start rawhide
error: Failed to start domain rawhide
error: SELinux policy denies access.

Downgrading the selinux-policy* packages to 3.13.1-190.fc24 corrected the problem. I currently have:

# rpm -qa selinux-policy\*
selinux-policy-targeted-3.13.1-190.fc24.noarch
selinux-policy-3.13.1-190.fc24.noarch
selinux-policy-devel-3.13.1-190.fc24.noarch
selinux-policy-doc-3.13.1-190.fc24.noarch

...and all four packages were updated to the new version.
Comment 1 Jeff Layton 2016-08-22 10:51:26 UTC 
Erm, downgrading corrected that problem, but totally broke firewalld. Unfortunately, I don't get an AVC denial in the audit log here so I can't use audit2allow to enable this.
Comment 2 Miroslav Grepl 2016-08-22 16:12:41 UTC 
Could you search for user_avc?

re-test it and run

# ausearch -m user_avc -ts recent


Thank you.

$ sudo ausearch -m user_avc -ts recent

The line below from /var/log/audit/audit.log seems related as well.
