Does a simpe 'fprintf(stderr,"STDERR\n"); fprintf(stdout,"STDOUT\n");' appear in xend.log? The downtime is the time during domU suspend/resume. Its best measuered by looking at domU dmesg. Boot the domU with 'initcall_debug' to get an understanding whats going on during such a suspend/resume cycle. Olaf
