libvirt users - Oct 2016 - Problems connecting to the libvirtd server

Hello everyone
I do not know if it is correct address this mailing lists but I can
not use libvirt.
I run compile libvirt version 2.2.0 into environment lfs stable with
qemu 2.7.0 and have not had any problems.
The program when it starts not report any errors in the log, with
activated debug level file.
Only when you try to connect with the following command virsh -c
qemu:///system remains hung without reporting any error either in the
logs that screen.
The command virsh -c test:///default list instead concludes on a regular basis.
I attach the file libvirt.log and libvirt.conf

Thank you
Stefano Ricci

Interesting. Maybe something else is causing the problem? Is there an
AppArmor running? What are the socket perms? Can you attach client debug
logs? (well, maybe paste them somewhere to pastebin-like service)

There is not AppArmor and SElinux is disabled.
The permits of the sock are as follows:
libvirt-sock-admin 0700 (rwx) root: root
libvirt-sock 0700 (rwx) root: root
libvirt-sock-ro 0777 (rwxrwxrwx) root: root
The libvirtd process runs with the root user.

Below you will find the link to the requested log:
http://pastebin.com/0jtpWU0h (libvirt_client.log command LIBVIRT_DEBUG
= 1 virsh -c qemu: /// system list --all)

Okay, the permissions look okay.

And from the client logs it looks like client is trying to connect but
the daemon is not replying. So client just hangs waiting for server
reply. So I've looked into daemon logs and found this:

2016-10-10 12:10:39.138+0000: 1383: error : virPidFileAcquirePath:422 :
Failed to acquire pid file '/var/lib/libvirt/qemu/capabilities.pidfile':
Risorsa temporaneamente non disponibile

(with my little Italian knowledge, this is Resource temporary unavailable)

This suggests that there might be a different libvirt daemon running.
Can you confirm that?
