Cloud Page

The two most common virtualization technologies used in a Cloud research environment are Xen and KVM.
Most prominent Cloud computing projects like OpenNebula and Eucalyptus support both Xen and KVM.
- Using Xen requires a (Xen-specific) special kernel which takes additional setup and maintenance time.
- KVM integrates nicely with the standard kernel and RedHat puts significantly more development time in KVM than in Xen.
Supporting both Xen and KVM on different node sets reduces the possibilities of doing reproducable large-scale measurements on DAS-4.

Therefore DAS-4 virtualization support will be focussed on KVM.

OpenNebula setup on DAS-4

DAS-4 currently has OpenNebula version 3.0.0 installed, which is the most recent stable release.

Check the OpenNebula installation page for information about the current OpenNebula setup.
To run a VM via OpenNebula as a regular user, see the OpenNebula user page.

DAS-4 currently supports Eucalyptus version 2.0.3, which is the most recent stable release.

Eucalyptus is basically an open source re-implementation of the Amazon cloud interface and protocols.
Check the Eucalyptus installation page for information about the current Eucalyptus setup.
To run a VM via Eucalyptus as a regular user, see the Eucalyptus user page.
