Hi John:
First, it's preferable to send questions like this to
openstack at lists.launchpad.net. I already added it to CC.
*- *sudo: unable to resolve host server3*:* is a problem related to
hostname. Be sure /etc/hostname and /etc/hosts are correct.
- Failed to add interface*:* Problem associated with networking module on
libvirt. Verify flat_interface and bridge interface work fine.
Regards,
JuanFra.
