It ought to be possible to enhance the "whacking" code to set the TSC based on the topologically nearest live CPU and then sanity-check against all others, repeating a few times to protect against SMIs etc. Ian _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
