Description Sakari A. Maaranen 2016-02-21 15:43:29 EST
Description of problem:
Installed the hyperv-daemons on a freshly installed Fedora 23 running on Hyper-V guest. Then enabled and started the services: hypervvssd, hypervkvpd, and hypervfcopyd

This seems to be Bug 1241636.
SELinux is preventing hypervkvpd from read, write access on the chr_file hv_kvp.

*****  Plugin device (91.4 confidence) suggests   ****************************

If you want to allow hypervkvpd to have read write access on the hv_kvp chr_file
Then you need to change the label on hv_kvp to a type of a similar device.
# semanage fcontext -a -t SIMILAR_TYPE 'hv_kvp'
# restorecon -v 'hv_kvp'

*****  Plugin catchall (9.59 confidence) suggests   **************************

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

Comment 2 Fedora End Of Life 2016-11-24 10:40:54 EST
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 3 Fedora End Of Life 2016-12-20 13:55:09 EST
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
