libvirt users - Feb 2013 - Failed to to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused

Hi,

I tried to build and run libvirt-1.0.1 on FSL PowerPC platform.
The connection to '/var/run/libvirt/libvirt-sock' is always refused.

# libvirtd -d
# export LIBVIRT_DEBUG=1
# export LIBVIRT_LOG_OUTPUTS="1:file:virsh.log"

# virsh -c qemu:///system list
2013-01-10 04:55:20.409+0000: 2574: info : libvirt version: 1.0.1

error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock':
Connection refused

Exactly it could work with libvirt-0.10.1. Below are the debug messages with
both versions.
# cat virsh.log

I checked the source codes of function src/rpc/virnetsocket.c and there's no
change on function virNetSocketNewConnectUNIX().
