libvirt users - Mar 2014 - Facing some error when restarting the libvirtd.

hi,

i installed libvirt-1.2.1 from the source with xen-4.3.1  and i am facing
the following error when restarting the libvirt.

Installation steps:
./autogen.sh --system --with-xen=yes --with-libxl=yes
make
make install


and in the libvirtd.conf i enabled the following things

auth_unix_ro
auth_unix_rw
unix_sock_group
unix_sock_ro_perms
unix_sock_rw_perms
unix_sock_dir
and libvirt logs

when running the following commands i got error message in libvirtd.log
tools/libvirtd -f /etc/libvirt/libvirtd.conf -d

Error message:
