• Node-side improvements:
  • Support for the KVM hypervisor
  • Compression & retries on Walrus downloads
  • Reworked caching (now with configurable limit)
• Web UI improvements:
  • Cloud registration with Rightscale (from admin's 'Credentials' tab)

Version 1.4 (2009-01-05) ¶

• Added new networking subsystem that no longer depends on VDE
• Added support for elastic IP assignment and security using the 'MANAGED' networking mode
• Cluster controller scheduling policy can now be configured in eucalyptus.conf (ROUNDROBIN and GREEDY currently supported)
• Cluster controller now handles concurrent requests (no longer have to restrict apache to allow only one connection at a time)

• Node Controller improvements:
  • Retrieval of images from Walrus instead of NFS-mounted file system
  • New caching and cleanup code, including start-time integrity checks
  • On-the-fly script-based generation of libvirt XML configuration
  • Script-based discovery of node resources (no assumptions about stat)
  • MAX_CORES overrides actual number of cores both down and up
  • Moved libvirt errors to nc.log and suppressed harmless ones
  • Serialized some Xen invocations to guard against non-determinism
  • Added proper swap creation, also "ephemeral" disk support
  • More robust instance state reporting to Cluster Controller
• Web interface improvements:
  • Added cloud/Walrus configuration, including clusters and VM types
  • Revamped 'credentials' tab with new options to edit user information and hide/show "secret" strings
  • Editing of user information for the administrator, including confirmation dialog for deletion of users
  • User-initiated password recovery mechanism
  • Fixed a couple of bugs: ' ' in username, spurious double additions
• Cloud Controller:
  • User, Cluster, and System keys are now stored in PKCS12 keystores and have moved to var/eucalyptus/keys
  • Configuration is handled entirely through the Web interface
  • Clusters dynamically added/started/stopped
  • Webservices operations complete up to EC2 2008-05-05 (w/o EBS):
  • "Elastic IP" address support
  • Image registration and attribute manipulation
  • GetConsole and RebootInstances support
  • Working Security Groups support for clusters in MANAGED network mode
  • See website for additional details, extensions, and caveats: http://eucalyptus.cs.ucsb.edu/wiki/API_v1.4
