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 the 2 old issues
above.
