1. Check out the community steps for Icehouse Horizon Customization http://docs.openstack.org/icehouse/config-reference/content/dashboard-custom-brand.html
2. Note that due to HA architecture there are 2 controllers with 2 copies of Horizon Services. So you need to make changes in both places.
3. These changes will be lost when u patch/upgrade VIO next time. In VIO 2.0 we will make Horizon Branding a core feature in the product, which will automate step #1 and avoid the issue of step #2. But in VIO 1.0 you need to do this manually.
You can't login by default to controllers. You need to login to OMS and ssh from there. something like >ssh controller01
Roadmap and other discussions are under NDA. I am happy to work with your group to set such a presentation and discuss those.
Yeah a presentation/discussion would be good.
Another quick question I could really do with knowing the answer is can you exploit the NSX load balancing functionality from Openstack e.g I want to assign two VMs and external VIP address and balance incoming IP traffic. I could do this using vsphere and NSX natively but how can I do this via the openstack dashboard?
