Host: Unisys ES7000/one, x86_64, 32 processors, 128 gb
memory
xen-3.1.2 –rc1 changeset 15489 compiled with
max_phys_cpus=64 and booted with dom0_mem=1024M 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 FYI
the patch submitted with preemption code does get called but it is
not working for us. Our team is still looking into it
- 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
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 124gb memory – run kernbench
2. 32-processor
64-bit SLES10 domVT with 124gb memory – run kernbench
3. 8-processor
64-bit SLES10 domU with 16gb memory - run kernbench
4. 8-processor
64-bit SLES10 domVT with 16gb 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 – run 100%
cpu intensive program
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.
