    So if you ever have a need to set the hostname of a newly provisioned Red Hat style box from your reverse dns PTR record that you’ve assigned to that machine (ideally through DHCP) here you go:

    sed -i s/localhost.localdomain/`host \`ifconfig eth0 | grep 'inet addr:'| cut -d: -f2 | awk '{ print $1}'\` | awk '/pointer/{print $5}' | sed s/\.$//`/ /etc/sysconfig/network

    Swap out the eth0 for whichever port is your primary.

    So I’ve been doing a lot of contract consulting lately, which is about to wrap up. I’ve been working with and for some movers and shakers in the cloud world, including John Willis (a good buddy and all-around great guy) and Randy Bias (cloud guru extraordinaire). I’ve had a great opportunity to use and learn many private cloud tools. Eucalyptus, VMOps, OpenNebula, and a few others as well. I’m going to try and find some time to write some detailed info about what I’ve learned soon. Maybe this week.

    Most lately, I’ve done some Chef development for some recipes to deploy a local, private cloud on your own hardware using Open Nebula. Just got done with a successful demo at CloudConnect where I set up a two-node cloud system plus a controller in just under a half hour in front of an audience of about 100 people. Biggest demo of my life, and it was the end result of literally a month’s work. We’re releasing the recipes open-source once I polish them up a little more. I’d really like to add kvm support and true LWRP templates for VM deployment. More to come, please stay tuned.
