[one-users] Help with datastore feature

[Ruben S. Montero]

Hi Robert,

>From your output it seems that the problem is probably at the libvirt
configuration. In particular:

Fri May 11 14:48:00 2012 [VMM][I]: WARNING: no socket to connect to

Could you double check the configuration hints at

http://www.opennebula.org/documentation:rel3.4:kvmg#kvm_configuration

Hope this help

Cheers

Ruben
