The cloud scheduler: a cloud-enabled distributed resource manager.
The cloud scheduler manages virtual machines on clouds configured with Nimbus, OpenNebula, Eucalyptus or EC2 interfaces to create an environment for batch job execution. Users submit their jobs to a batch job queue like Condor, Sun Grid Engine, or Platform LSF, and Cloud Scheduler boots VMs to suit those jobs, creating a malleable, virtual environment for efficient job execution.
For more documentation on the cloud scheduler, please refer to the following pages:
There are two configuration files that define the function of the cloud scheduler. These are:
The general (or central) cloud scheduler configuration file contains fields for defining cloud scheduler program functionality, including Condor job pool con- figuration information, logging information, and default cloud resource config- uration options.
The cloud scheduler config file can be manually specified on the command line
when the cloud scheduler is run via the [-f FILE | --config-file=FILE] option,
or can be stored in the following locations:
~/.cloudscheduler/cloud_scheduler.conf
/etc/cloudscheduler/cloud_scheduler.conf
Note: the cloud scheduler will attempt first to get the general configuration
file from the command-line, then from the ~/.cloudscheduler directory, and finally from the
/etc/cloudscheduler directory.
The cloud resource configuration file contains information on the cloud-enabled clusters that the cloud scheduler will use as resources. Clusters in this con- figuration file will be used by the cloud scheduler to create and manage VMs. See the cloud_resources.conf file for an explanation of cluster configuration parameters.
The cloud resource config file can be specified on the command-line with the [-c | --cloud-config=FILE] option. If the cloud resource config file is not specified on the command line, it will be taken from the location given in the cloud_resource_config field of the cloud_scheduler.conf file.

You can install these on RHEL5 (and clones) with the following:
$ yum install PyXML
$ wget 'https://fedorahosted.org/suds/attachment/wiki/WikiStart/python-suds-0.3.6-1.el5.noarch.rpm?format=raw'\
$ -O python-suds.el5.noarch.rpm
$ yum localinstall python-suds.el5.noarch.rpm
$ wget http:https://boto.googlecode.com/files/boto-1.8d.tar.gz
$ tar xvf boto-1.8d.tar.gz
$ cd boto-1.8d
$ python setup.py install
On Mac OS X, using Macports, you can install these with the following (say you're using python 2.6):
$ sudo port install py26-xml py26-suds py26-boto
To install cloud scheduler, as root, run:
$ python setup.py install
