New Features

1. Support for Virtual Clusters

2. Virtual frontends and virtual compute nodes are now supported. The network for a VM frontend its VM compute nodes are contained within its own VLAN. A virtual cluster is added with “rocks add cluster fqdn=X ip=Y num-computes=Z”. See “rocks add cluster help” for details.

3. Can build rolls outside of Rocks source tree

All roll building support files are under /opt/rocks/share/devel.

4. Can reconfigure a compute node’s network without rebooting

Rocks commands were added to support this. See the documentation for the procedure.

5. Distribution moved to /export/rocks/install

No longer require NFS on the frontend to properly host a Rocks Distribution. This will make moving user accounts to an external NFS server easier.

6. Fine-grained control over the “boot” and “install” kernel for Xen VMs

Rocks commands where added to support this feature. For details, execute: “rocks help installprofile” and “rocks help bootprofile”.
