Please attach the .wtl file from the job. Also, it can be useful if you attach a screenshot of Task Manager's "Processes" tab before and after the process disappears. Thanks! (From the picture, it seems like diskio.exe is picking a runtime of 15 minutes or so, rather than the 3 days that are used for newer OSes). Created attachment 481814 [details]

(In reply to comment #2) > (From the picture, it seems like diskio.exe is picking a runtime of 15 minutes > or so, rather than the 3 days that are used for newer OSes). Hi Paolo, I get the same result when run Disk Stress and Disk Verification jobs. I upload screen-shot of Task Manager's "Processes tab. Please see the attachment. Thanks! I also can reproduce this bug in Win7-32 guest when test the "Disk Stress" blk WHQL job,run a few minutes the job windows will disappeared, and the guest can not reboot or shutdown normally,if I want to run the "Explorer" it will show up the error message: "There is not enough free memory to run this program.Exit one or more programs,and then try again." I found the job's processes are closed but the memory not be freed , the number of processes before windows disappeared is 40 ,the number of processes after windows disappeared is 37 and the Physical Memory:53% still . Version-Release number of selected component (if applicable): kernel-xen-2.6.18-245.el5.x86_64.rpm xen-3.0.3-123.el5.x86_64.rpm xenpv-win-1.3.4-2.el5.noarch.rpm Is it possible to get the Win7-32 wtl file? (Forget about my comment 3, I was confusing "disk stress" and "disk verification". Created attachment 482582 [details]
win7 -32 wtl file
attach the win7-32 wtl file
This is not the WTL file for disk {stress,verification}. If you prefer, just generate a .cpk and I'll get the right log myself (.cpk files are just cab files).

Verified with the following pkgs: xenpv-win-1.3.4-6.el5 kernel-xen-2.6.18-245.el5.x86_64.rpm xen-3.0.3-123.el5.x86_64.rpm WLK1.5 Disk Stress on all Windows Oses(2k3-32/64,2k8-32/64,7-32/64,xp-32,2k8-r2) pass. Test version: xenpv-win-1.3.4-6.el5 kernel-xen-2.6.18-245.el5.x86_64.rpm xen-3.0.3-123.el5.x86_64.rpm WLK1.5 Test result: Disk Verification on all Windows Oses(2k3-32/64,2k8-32/64,7-32/64,xp-32,2k8-r2) pass. So change bug status to verified. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.

Created attachment 481797 [details] disk stress process will disappear after run a few minutes Description of problem: Disk Verification (or Disk Stress) job process will disappear after run a few minutes in win2k3-32&64 guest. Version-Release number of selected component (if applicable): kernel-xen-2.6.18-245.el5.x86_64.rpm xen-3.0.3-123.el5.x86_64.rpm xenpv-win-1.3.4-2.el5.noarch.rpm How reproducible: 100% Steps to Reproduce: 1. Set the DWORD value "EnumerateDevicesOverride" to 3 in the registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\rhelscsi", 2. Run Disk Stress or Disk Verification job with below configure: disk = [ "file:/var/lib/xen/images/win2k3-64b-50G,hda,w", "tap:aio:/var/lib/xen/images/disk2,xvda,w" ] 3. Please see attachment for more details. Actual results: 1. In win2k3-32 and win2k3-64 guest, disk Verification process will disappear after run a few minutes. 2. In DTM studio job queue, this job will keep Running status all along. But in fact, the job didn't run. Expected results: The Disk Verification pass. The Disk Stress pass. Additional info: When I set the DWORD value "EnumerateDevicesOverride" to 1, I get the same result.
