cpu specific fields in getdomaininfo

cpu specific fields in getdomaininfo

[Kip Macy]

I'd like to know what you're recommendations are for cpu_time,
processor, and per-exec_domain flags.

>From my usage standpoint, cpu_time should be the highest of all of the
vcpus, PAUSED and BLOCKED should be the logical AND of all the vcpus
and RUNNING should be the logical OR of all of the vcpus, processor
should simply be moved to getvcpucontext or be made into separate
field along the lines of the bitmask discussed previously.

Thanks.

None of these fields make much sense to aggregate and ought probably to 
disappear from GETDOMAININFO. Possibly cpu_time should be the *sum* of 
all individual vcpu times. I think your method aggregating 
paused/blocked/running is probably the sanest.
