[one-users] libvirt and kvm permission problem.

[Idafen Santana Pérez]

Thanks a lot Ignazio,

I've changed this parameters:

unix_sock_group = "libvirt" -> unix_sock_group = "oneadmin" (oneadmin
is my cloud group, shame on me I've called user and group the same)

unix_sock_rw_perms = "0770" -> unix_sock_rw_perms = "0777"

I am not sure at all about changing unix_sock_rw_perms, but it doesn't
work unless I do that.

Then I restarted the libvirtd  and one daemons and it seem to be working.

Regards,
Idafen
