[RFC 0/2] Domain Groups

[RFC 0/2] Domain Groups

[Chris]

The following Domain Groups patches provide a VMM-backed framework to
consolidate information about a collection of domains.  Today that group
information can be integrated with both the scheduler and XSM.  In the future,
the same information could support domain disaggregation efforts.

As a demonstration, the 'xm' tool is augmented with several new commands:

grp-create: create a domain group
grp-migrate: migrate all domains in a group
grp-shutdown: shutdown all domains in a group
grp-destroy: destroy all domains in a group
grp-reboot: reboot all domains in a group
grp-pause: pause all domains in a group
grp-unpause: unpause all domains in a group
grp-save: save all domains in a group
grp-restore: restore domains with their group information
grp-join: add domain to a group
grp-list: list groups and their members

The following patches should apply cleanly to xen-unstable cs 16618.

No grp-leave?

There are two groups created by the VMM during boot: "Null Group" and  
"Group 0."  Dom0 starts in group 0; all other domains start in the  
null group and stay there until they are joined to another group.   
The grp-create command creates both a group and domains, then joins  
the domains to the new group.  Joining the null group is effectively  
leaving a group.
