It seems more useful and intuitiveto always total the VCPU times to obtain the CPU time. I think we used to return the highest VCPU time as domain time. Someone decided to instead sum across all VCPU times, but I guess forgot to remove the conditional. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
