An issue was detected on packet filter script (iptables.sh), which allows VPN users to access external hosts.
After Trove installation (commit 92575af7c49b5676c08a0366707ad0dd9afbf0f8), I ran the first sinlge-tenant database server. I didn't know, but this server connects to external network (ext-net), so to make things easier (a.k.a. Trove guest agent configuration), I decided to add a few lines in DNS external view.
We started the project using just 3 nodes (1 controller + 2 nodes). Now, another machine was allocated to project: openstack3. Some related files (belonging to earlier computes+network nodes) was modified to allow better deployment (whithout non-fatal errors, I mean :).
