The error that you are reporting is simply telling you that the libvirtd
daemon is not running.  You can confirm this with

ps auxw | grep libvirtd

root      3329  0.0  0.0 600440  8420 ?        Sl   10:22   0:00
libvirtd --daemon

If it is not running then attempt to start it with:
    service libvirtd start

To have it start at system startup run
     chkconfig libvirtd on

I have one system where, for some reason 'service libvirtd start' fails,
but running

/etc/init.d/libvirtd start

works.  I have not had a chance to determine why yet.  Also, if libvirtd
fails to start, check your log files /var/log/messages /var/log/boot.log
/var/log/audit/audit.log for errors.  You could also try temporarily
disabling selinux enforcement with "setenforce 0".  Use 'setenforce 1'
to renable it.
