Detailed Description

Condor Cloud provides an IaaS cloud implementation based on Condor using deltacloud ( as the front end to control the cloud. It supports multiple hosts/nodes, caching of images on each node for quicker startup, and copy on write (COW) image files so the images do not need to be copied per-instance. It uses libvirt/KVM to launch instances on the hosts and is fairly configurable.

Benefit to Fedora

Condor Cloud would give Fedora a relatively easy to setup, robust cloud IaaS solution.


The cloud itself is all up and running. The deltacloud driver would have to be merged with upstream codebase. We will also need to create a package for the configuration and scripts needed to set up condor as the backend to deltacloud.

How To Test

You will need to install the Condor package and then get the source from:

There is an INSTALL document in the source, you can see it here:;a=blob_plain;f=INSTALL.txt

I will endeavor to get this into an RPM asap.

User Experience

This cloud could be used directly by end users via the Deltacloud API. It can also be used as a backend for Aeolus, although there is some testing/integration work to be done on the Aeolus side.


condor RPM deltacloud RPM condor-cloud RPM (yet to be made).

Mostly we depend on getting the deltacloud driver upstream. I have posted the git repo location to the list and am awaiting review for acceptance. I have talked to David Lutterkort and it sounds like it will not be a problem.

Contingency Plan

None necessary, revert to previous release behaviour.
