Adrian Brock suggested that I post a cross reference to a thread on the user forum.http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= also appears that JSR 77 standardizes on cluster management as well, since most of the components are supposed to list the VMs that they have threads running in.With blade servers, grids and data centers on demand gaining ground, management of virtual systems is becoming important as well.I would appreciate further comments.
