Description Giulio 'juliuxpigface' 2017-01-15 16:44:06 UTC 
Description of problem:
I upgraded from F25 to Rawhide and, after the reboot and the login, I found this issue.
SELinux is preventing spice-vdagentd from 'getattr' accesses on the filesystem /sys/fs/cgroup/systemd.

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

If si crede che spice-vdagentd dovrebbe avere possibilità di accesso getattr sui systemd filesystem in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c 'spice-vdagentd' --raw | audit2allow -M my-spicevdagentd
# semodule -X 300 -i my-spicevdagentd.pp

Description of problem:
Happens during boot of current Fedora Rawhide Workstation live image (20170115.n.0) in a VM. Seems to prevent copy/paste between host and guest working: with `enforcing=0`, it works.

Comment 3 Vít Ondruch 2017-02-08 16:25:29 UTC 
This prevents autoresizing as well :/

$ rpm selinux-policy -q

Comment 4 Fedora End Of Life 2017-02-28 10:59:26 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.
Comment 5 Adam Williamson 2017-03-13 23:35:20 UTC 
Nominating as a Final blocker: this seems like a violation of "There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop" - https://fedoraproject.org/wiki/Fedora_26_Final_Release_Criteria#SELinux_and_crash_notifications - at least in the case of VMs. Also proposing as an Alpha FE, as the inability to paste into / copy from an Alpha live image is a pain.
Comment 6 Mike Ruckman 2017-03-16 18:11:56 UTC 
Discussed at today's Go/No-Go meeting. This would be good to get pulled in for Alpha release if a tested fix is available.

The decision was made to classify this bug as an AcceptedBlocker (Final) as it violates the following criteria:

"There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop."
