Great stuff Rob. Would be even better if Dell would create a playground for Crowbar (or did I miss that?).
What are you thinking of? I agree we need more collaboration. I’m interested to know if you have something specific in mind?
Something like a virtual server farm where people could see Crowbar in action, testdrive the setup process (see how easy it is), several different configurations and use cases and (Dell needs to make money, too) packages of servers and software to create private clouds for i.e. small, medium and large customers. Just brainstorming, happy to continue discussion in more detail via email…

I tried the lasted ubuntu ISO to install crowbar on a physical server. The install did not work, and crowbar does not run.
Is there a process to uninstall and reinstall?
Is there a way to install crowbar without FQDN. I am installing this on a rack of servers that are on private IP’s with one one node providing NAT and DNS via dnsmasq, so FQDN is not needed.
The best place for questions like this is the Crowbar listserv. If you boot from the ISO again then it will reinstall over the old install. Crowbar requires an FQDN because it has DNS. It will take some configuration to setup your own NAT – this is an active topic on the list right now.
Hi Rob,
I’m in the middle of installing Crowbar on two servers, ultimately to get OpenStack up and running. The plan is for HostA to be our Admin node and the HostB a non-Admin node. Both have two NIC’s with one NIC (eth0) on each connected to the internet, and the other NIC (eth1) connected locally.
I am confused as to if/how I should configure bc-template-network.json for this setup, prior to configuring Crowbar. We want the admin node to be accessible via the internet and then, once OpenStack is running, to be able to access the VM’s deployed by it over the internet. For internet access I have been allocated an IP range of 6 addresses to use.
To complicate things the physical servers are hosted remotely, so it’s not a simple matter to re-install from ISO if I get it wrong. So, ideally, I’d like to get it right the first time.
Any guidance would be greatly appreciated.

Bobby,
We’ve got resources for network configuration on the crowbar wiki (https://github.com/dellcloudedge/crowbar/wiki/Annotated-network-json-file) but that is one of the trickier configurations. I strongly recommend pinging the Crowbar listserv (https://lists.us.dell.com/mailman/listinfo/crowbar).
The only part of the network configuration you need to do before install is the network list.
