Interface-wise: I'm wondering if at the Xen or libxl level we really need to have a whole new set of hypercalls, at least to implement #1. Would it make sense for certain schedulers to automatically switch to "no accounting" mode when the hard_affinity of a vcpu is limited to one vcpu, and no other vcpus are also limited to that one vcpu? -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
