Hi, seems I'm affected by this as well (ran into it trying devstack in 16.4 LTS). Service libvirt-bin stop; service libvirt-bin start fixed this for me. As soon as I do service libvirt-bin restart the socket vanishes again from /var/lib/libvirt for me.
The odd thing is, lsof -p <libvirt-bin PID> shows the socket as opened while it doesn't exist: root@os-gate-u16:~/devstack-gate-test/ansible# lsof -U -p 28097 | grep /var/run/libvirt/libvirt-sock systemd 1 root 67u unix 0xffff88010cea8f00 0t0 820644 /var/run/libvirt/libvirt-sock type=STREAM systemd 1 root 68u unix 0xffff88010cea9e00 0t0 820645 /var/run/libvirt/libvirt-sock-ro type=STREAM libvirtd 28097 root 3u unix 0xffff88010cea8f00 0t0 820644 /var/run/libvirt/libvirt-sock type=STREAM libvirtd 28097 root 4u unix 0xffff88010cea9e00 0t0 820645 /var/run/libvirt/libvirt-sock-ro type=STREAM root@os-gate-u16:~/devstack-gate-test/ansible# lsof /var/run/libvirt/libvirt-sock lsof: status error on /run/libvirt/libvirt-sock: No such file or directory lsof 4.89 latest revision: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/ latest FAQ: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/FAQ latest man page: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/lsof_man usage: [-?abhKlnNoOPRtUvVX] [+|-c c] [+|-d s] [+D D] [+|-E] [+|-e s] [+|-f[gG]] [-F [f]] [-g [s]] [-i [i]] [+|-L [l]] [+m [m]] [+|-M] [-o [o]] [-p s] [+|-r [t]] [-s [p:s]] [-S [t]] [-T [t]] [-u s] [+|-w] [-x [fl]] [--] [names] Use the ``-h'' option to get more help information. root@os-gate-u16:~/devstack-gate-test/ansible# -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1583688 Title: libvirt-sock not recreated on service restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1583688/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
