Additional info:

Following the test case at: 

    https://fedoraproject.org/wiki/QA:Testcase_VirtSandbox_CommonSetup

   [root@omiday ~]# rpm -qa | grep -i lxc
   libvirt-daemon-lxc-2.2.0-1.fc25.x86_64
   libvirt-daemon-driver-lxc-2.2.0-1.fc25.x86_64

The daemon-driver package is empty?

   omiday ~ $ rpm -ql --scripts --triggers libvirt-daemon-lxc
   (contains no files)

Comment 1 M. Edward (Ed) Borasky 2017-02-11 22:11:05 UTC
I'm seeing this in Virtual Machine Manager too. I'm trying to open a new connection for LXC. I went to the "New Connection" menu and selected "LXC". 

Unable to connect to libvirt.

no connection driver available for lxc:///

Libvirt URI is: lxc:///

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 904, in _do_open
    self._backend.open(self._do_creds_password)
  File "/usr/share/virt-manager/virtinst/connection.py", line 148, in open
    open_flags)
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 105, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: no connection driver available for lxc:///

I'm assuming I need to install some more packages or enable and start a service or both, but it's not clear how to do that.

Comment 2 NM 2017-03-30 01:47:29 UTC
Same here. 
In addition even with selinux in Permissive mode and run as root:

virsh --connect  qemu:///session  
 
or any other virsh command like say: 

virsh --debug 2 --connect qemu:///system

does absolutely nothing - with no debug or error message, or any other output. 

No errors reported by libvirtd:

Comment 3 Fedora End Of Life 2017-11-16 19:32:38 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. 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bug reports from releases that are no longer maintained.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 '25'.

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 25 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 4 Fedora End Of Life 2017-12-12 11:03:44 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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
bug.

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