Ubuntu 12.04 Alpha + Beta Kernel Panic Fix

If you are getting a Kernel Panic accompanied by text such as

init: log.c:786: Assertion failes in log_clear_unflushed:
 log->remote_closed

Then see this thread: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/935585 regarding a bug introduced in a recent upstart package.

Fix is simple

1. apt-get install python-software-properties
2. add-apt-repository ppa:jamesodhunt/bug-935585
3. apt-get update
4. apt-get upgrade

When you reboot all should be great thanks to James Hunt.

OpenStack Essex Keystone Changes – script showing use

The latest release of OpenStack Essex has changed the way Keystone is managed.  Rather than most of the work being done by nova-manage, this has moved to a ‘keystone’ client command (which can be found in the Ubuntu package, python-keystoneclient).

An example of its use can be seen here: https://github.com/uksysadmin/OpenStackInstaller/blob/essex/keystone-services.sh
