RE: [libvirt] error: unable to connect to '/usr/local/var/run/libvirt/libvirt-sock': Connection refused

Hi, ozaki Thank you for your reply. As you said, libvirtd is not running. I have tested, there was error: ------------------------------------------------------------------------------------------------------- root@forest:/var/run/libvirt# libvirtd start libvir: Network Config error : cannot create bridge 'virbr0': File exists 12:34:30.525: warning : qemudStartup:521 : Unable to create cgroup for driver: No such device or address 12:34:30.598: warning : lxcStartup:1460 : Unable to create cgroup for driver: No such device or address ---------------------------------------------------------------------------------------------------------- How can I fix it?

In the second case, you can confirm my guess by doing 'lsof |grep libvirt-sock'. ozaki-r
