Hi, I am working on SMP for xen-ia64. The first step was to be able to use all the cpus but without considering VCPUs migration ie VCPU must be pinned to one CPU. Is it the same policy on x86 ? The migration cost is rather high on ia64 and may require a lot of inter-CPU traffic for coherency (TLB and cache management at least). What about x86 ? How is the wbinvd instruction paravirualized/virtualized ? Thank you for your comments. Tristan. _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel
