[Rdo-list] the hostname returned by metadata service ?

[Zhao, Xin]

Hello,

I have a question about metadata service.

We set up a multi-hosts testbed on RHEL6 from RDO icehouse.

Inside the instance, hostname shows as expected by the dhcp server, as 
shown below:

[root at host-172-10-0-8 ~]# hostname -f
host-172-10-0-8.openstack.bnl.gov

[root at host-172-10-0-8 ~]# nslookup host-172-10-0-8.openstack.bnl.gov
Server:        172.10.0.3
Address:    172.10.0.3#53

Name:    host-172-10-0-8.openstack.bnl.gov
Address: 172.10.0.8

But the hostname returned by metadata is different and not reachable:

[root at host-172-10-0-8 ~]# curl 
http://169.254.169.254/latest/meta-data/hostname
server-626663d6-cf90-4f2a-b888-7c3b6bdd1841.novalocal[root at host-172-10-0-8 
~]#

[root at host-172-10-0-8 ~]# nslookup 
server-626663d6-cf90-4f2a-b888-7c3b6bdd1841.novalocal
Server:        172.10.0.3
Address:    172.10.0.3#53

*** Can't find server-626663d6-cf90-4f2a-b888-7c3b6bdd1841.novalocal: No 
answer


Note that, the hostname returned by metadata is the same as shown in the 
"Name" column from the "nova list" command.

How can we get the metadata service return the real hostname?

Thanks,
Xin
