I just want to make sure that everyone knows that the LCA2014 call for proposals is open. There are two calls this time around — a call for proposals and a call for miniconfs. The call for proposals closes on 6 July, so you don’t have heaps of time left to submit something. So, if…
Merged in Havana: fixed ip listing for single hosts
Nova has supported listing the fixed ips for a single host for a while. Well, except for that time we broke it by removing the database call it used and not noticing. My change to fix that situation has just landed, so this should now work again. To list the fixed ips used on a…
Michael’s surprisingly unreliable predictions for the Havana Nova release
I should start out by saying that because OpenStack is an open source project, it is hard to know exactly what will land in Havana — the developers are volunteers, and sometimes things get in the way of them doing the work they intended. However, these are the notes I wrote up on the high…
Getting started with OpenStack development
I just gave my presentation at the Havana Conference about how to get started with OpenStack development. A few people asked for my slide deck, so I am posting it here. The talk was taped, and I am sure some more formal release will happen in the future, but I wanted to get this out…
Faster pip installs
Last week with the help of the lovely openstack-infra people, I discovered that you can have a local cache of pip downloads. This speeds up rebuilding test environments when you need to jump between branches with different dependencies. Its as simple as chucking something like: export PIP_DOWNLOAD_CACHE=~/cache/pip …into your .bashrc or equivalent.
Merged in Havana: configurable iptables drop actions in nova
LaunchPad bug 1013893 asked nicely if the drop action for iptables rules created by nova-network could be configured. The idea here is that you might want to do something other than a plain old drop — for example logging before dropping. This has now been implemented in Havana. To configure the drop action, set the…
Upgrade problems with the new Fixed IP quota
In the last few weeks a new quota has been added to Nova covering Fixed IPs. This was done in response to LaunchPad bug 1125468, which was disclosed as CVE 2013-1838. To be honest I think there are some things the vulnerability management team learned the hard way with this disclosure. For example, we didn’t…
Havana Nova PTL elections
This is just a quick reminder that there are only a couple more days to vote in the Nova PTL elections for the Havana cycle. If you’re eligible to vote, you should have a voting URL in your email. The candidates: Russell Bryant — announcement Michael Still — announcement The incumbent PTL, Vishvananda Ishaya, has…
Redshirts
I was super excited to get my hands on the latest John Scalzi book because I’ve really liked his previous stuff. Unfortunately while this book is fun I feel that the underlying concept is pretty weak… Its more of a toy boy than something which makes you think, which is a disappointment to me. Don’t…
Earthbound
This is the third book in the Marsbound series. The Others have just turned off all electronics on Earth, and now we need to survive. One problem with this book is that it jumps straight into the action — I had to go back and re-read Marsbound and Starbound in order to understand what was…
