I have no way of knowing at some point later which vcpus are up or down? I don't see any cost to this other than during the getdominfo hcall. The ones you can retrieve info about are up. The ones you can't, are down. :-) Let me put it this way: I reserve the right in future to change my mind and free the vcpu info structures for vcpus that are down (and re-allocate when they come back up). If I do that then you will not get info about them via hypercalls. There's no good reason to return info about them -- you can infer they are 'down'/non-existent from their absence -- so why bother? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
