When /etc/nova/nova.conf does not have specify dhcp_domain to empty string, a default string of '.novalocal' is returned by the meta data service. So we need to just split the string and pick the first one in the array. ``` $ curl http://169.254.169.254/latest/meta-data/hostname testvm-1.novalocal $ curl http://169.254.169.254/latest/meta-data/public-hostname testvm-1.novalocal $ curl http://169.254.169.254/latest/meta-data/local-hostname testvm-1.novalocal ```
