[Xen-devel] UPDATE: Test results on Unisys ES7000 64x 256gb using xen-3.1.2-rc1 c/s 15490 -1 new issue, 2 old issues

The RESULTS section in the original message I sent needs to indicate that there is 1 new issue.

Additional info for this new issue, the serial port shows this entry:

Cannot handle page request order 0!

When the host is booted with half of the resources, 32 processors and 128 gb memory, test 11_create_concurrent_pos of xm-test does not fail.

Any ideas what could be causing this to fail when there is ample host memory?

Subject: Test results on Unisys ES7000 64x 256gb using xen-3.1.2-rc1 c/s 15490 -1 new issue, 2 old issues

Host: Unisys ES7000/one, x86_64, 64 processors, 256 gb memory

xen-3.1.2–rc1 changeset 15490 compiled with max_phys_cpus=64 and booted with dom0_mem=2048M and numa=on

OLD ISSUES:

Bug #1037 - Shutdown of large domains takes a long time, during which time dom0 is not interruptible (due to the synchronous tearing down of the memory map) – for example, shutdown of 180gb domu causes 5 min 15 sec dom0 unresponsiveness
Bug #940 - Must specify hpet=disable kernel parameter to get 32-bit SLES10 domVTs to boot; narrowed down to c/s 14436 but the patch originator cannot recreate on his hardware

NEW ISSUE:

Xm-test gets this failure, but we had never run it with 256GB memory before so it may not be a regression:

11_create_concurrent_pos failed with:

Error: (12, 'Cannot allocate memory')

So increased dom0_mem parameter to 4096M, rebooted, and reran but get the same problem; will test today with less host memory to see if still fails

TESTS include running xm-test and also attempting to boot and run programs in the following domUs and domVTs (running domains #s 3 through 10 simultaneously):

1. 32-processor 64-bit SLES10 domU with 248gb memory – run kernbench

2. 32-processor 64-bit SLES10 domVT with 248gb memory – run kernbench

3. 32-processor 64-bit SLES10 domU with 64gb memory - run kernbench

4. 32-processor 64-bit SLES10 domVT with 64gb memory – run kernbench

5. 8-processor 32-bit SLES10 domU with 4gb memory – run kernbench

6. 8-processor 32-bit SLES10 domVT with 4gb memory (booted with hpet=disable) - run kernbench

7. 8-processor 32-bit PAE SLES10 domVT with 16gb memory (booted with hpet=disable) - run kernbench

8. 8-processor 64-bit Windows 2003 Enterprise Edition domVT with 16gb memory – booted but could not log in because OS needs to be activated

9. 2-processor 32-bit Windows XP domVT with 4gb memory – run 100% cpu intensive program

10. 1-processor 32-bit Windows 2003 Server domVT with 4gb memory – run 100% cpu intensive program

RESULTS:

All tests were successful, except for 1 new issue and 2 old issues (see above).
