Xen devel - Oct 2007 - [IA64] Weekly benchmark results [ww42]

Hi,

I report a benchmark result of this week on IPF using
ia64/xen-unstable and ia64/linux-2.6.18-xen.

The failures related with direct IO were fixed.

pselect01 on domU and semop01 and semop02 on domVTi failed but passed
manually.

TEST ENVIRONMENT
    Machine          : Tiger4
    Kernel           : 2.6.18.8-xen
    Changeset        : 16120:3f6e855d218b (ia64/xen-unstable)
		       257:6cac8ecd995d   (ia64/linux-2.6.18-xen)
    Dom0 OS          : RHEL4 U2 (2P)
    DomU OS          : RHEL4 U2 (8P, using tap:aio)
    DomVTi OS        : RHEL4 U2 (8P, with PV-on-HVM drivers)
    Scheduler        : credit

TEST RESULT
  DomU:
    unixbench4.1.0    : Pass
    bonnie++-1.03     : Pass
    ltp-full-20061121 : 1/831 FAIL (see attachment)
    iozone3_191       : Pass
    lmbench-3.0-a5    : Pass
  DomVTi:
    unixbench4.1.0    : Pass
    bonnie++-1.03     : Pass
    ltp-full-20061121 : 2/831 FAIL (see attachment)
    iozone3_191       : Pass

Hi. Have you got any idea which c/s resolved it?
By quick scanning the change log, I wasn''t able to find it.
Since the dio issues begun when xenLinux base version was
changed from 2.6.16 to 2.6.18, I supposed that it was
not Xen VMM issue, but linux kernel or ltp issue.
However nothing backed it up.

I think diotest failures are caused by bugs of Linux kernel 2.6.18,
because the native 2.6.18 kernel also fails and failures disappeared by
updating to 2.6.18.8.
