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 a bare metal machine, not a VM to run it on.
  • You will need to install the condor-cloud rpm.
  • Read and follow directions in /usr/share/doc/condor-cloud/fedora_install.txt.

If you wish to set up other nodes you will need to install condor-cloud-node rpm on each machine and again follow instructions in /usr/share/doc/condor-cloud/fedora_install.txt.

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).

condor-cloud RPM is now built. Deltacloud driver is in upstream and a release is pending very soon.

Contingency Plan

None necessary, revert to previous release behaviour.

Release Notes

Condor Cloud is an Infrastructure as a Service (IaaS) cloud implementation. It allows you to create as many VMs from an image or images as you wish, distributing them across a pool of configured hosts. The user interface is the Deltacloud API ( The backend is implemented using Condor ( which in turn starts VMs using libvirt and KVM.
