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

[Liu, Zhentao]

Hi, ozaki

Thank you for your reply. As you said, libvirtd is not running. I have tested, there was error:

-------------------------------------------------------------------------------------------------------

root at 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?

Regards

Zhentao

I guess libvirtd is not running, or running but waiting on
'/var/run/libvirt/libvirt-sock'
where your virsh is try to look up
'/usr/local/var/run/libvirt/libvirt-sock'. In the second
case, you can confirm my guess by doing 'lsof |grep libvirt-sock'.
