This is one example of a configuration option which I'd prefer to see done with the (planned) new CPUID interface. The value here doesn't have any impact on the hypervisor, so a configuration option is free to be chosen entirely by the toolstack, and would also become inherently per-domain configuration rather than global. Can I talk you into deferring this change until the CPUID interface is sorted, to avoid introducing yet another command line option? ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
