[Openstack] Juno: my_ip parameter in nova.conf does not take FQDN?

Good day,

It appears that parameter my_ip in nova.conf on a compute node expects a dotted decimal IP address only. Supplying a FQDN results in an error:

2014-11-26 16:31:05.410 31879 TRACE nova.virt.libvirt.driver   File "/usr/lib/python2.7/dist-packages/nova/objects/fields.py", line 313, in coerce
2014-11-26 16:31:05.410 31879 TRACE nova.virt.libvirt.driver     raise ValueError(six.text_type(e))

2014-11-26 16:31:05.410 31879 TRACE nova.virt.libvirt.driver ValueError: failed to detect a valid IP address from u'openstack-compute.ucslab.cisco.com'

If I simply replace the FQDN with 10.48.58.53, it starts to work:

Is that intentional? Other services appear to be fine when configured with a FQDN, so I'm wondering.

I'm on Ubuntu 14.04-1 with Juno.
