Description of problem:
On fc23 when connecting to libvirt (qemu:///session) as regular user it sometimes fails with the above message being shown in the logs.

The error is this:

Jan 24 18:47:32 akhos libvirtd[24143]: libvirt version: 1.2.18.2, package: 1.fc23 (Fedora Project, 2015-12-24-00:55:42, buildhw-12.phx2.fedoraproject.org)
Jan 24 18:47:32 akhos libvirtd[24143]: Failed to acquire pid file '/run/user/1000/libvirt/libvirtd.pid': Resource temporarily unavailable
Jan 24 18:47:32 akhos systemd[1]: Received SIGCHLD from PID 24143 (libvirtd).
Jan 24 18:47:32 akhos systemd[1]: Child 24143 (libvirtd) died (code=exited, status=1/FAILURE)

An example of failure:
dcaro@akhos$ virsh list
error: failed to connect to the hypervisor
error: no valid connection
error: Cannot write data: Transport endpoint is not connected

This happens when that pid file does not exist, but it's created a couple seconds after, and once it's there, the virsh command start working. Though after a minute or so it disappears again and it starts failing again.


Version-Release number of selected component (if applicable):
Jan 24 18:47:32 akhos libvirtd[24143]: libvirt version: 1.2.18.2, package: 1.fc23 (Fedora Project, 2015-12-24-00:55:42, buildhw-12.phx2.fedoraproject.org)


It seems that restarting the libvirtd daemon solves nothing

Thanks!
