Tracked it down a little more: running: "bonnie++ -s 2048 -d /var/tmp -u root" in dom0 watching: "iostat -x -d 2" gives: await svctm %util 6953.33 111.11 100.00 9039.17 166.67 100.00 (...) man iostat says: "%util: Percentage of CPU time during which I/O requests were issued to the device (bandwidth utilization for the device). Device saturation occurs when this value is close to 100%. Running: "mpstat 3 5" while bonnie++ runs shows: 15:51:33 CPU %user %nice %system %iowait 15:51:36 all 0.00 0.00 0.00 99.67 15:51:39 all 0.00 0.00 0.00 100.00 15:51:42 all 20.33 0.00 14.00 65.67 15:51:45 all 0.00 0.00 0.00 100.00 15:51:48 all 0.00 0.00 0.00 100.00 man mpstat says: "%iowait: Show the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request." So as far as i understand my ATA drive locks up my CPU... Where is the problem?? I am running: xen2.0.7 on suse 9.3 with 2.6.11.4-21.8-xen Thanks Dirk _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
