Hi,

I report a benchmark result of this week on IPF using
xen-unstable and linux-2.6.18-xen. # not ia64

- The hypervisor of 19914:d6c1d7992f43 hung up while booting.
  We used 19912:721c14d7f60b.

- Xend of 19912:721c14d7f60b did not run on Python 2.3.
  We removed some codes Python 2.3 do not support. # set()

- DomVTi cannot use tap:aio. When a guest started, dom0 hit BUG_ON()
  at mm/rmap.c:522 and the guest hung up. Thus we used vbd.
  I attached the dom0 call trace.
  # Notice that DomU can use tap:aio.

- On domU, pselect01 failed, but passed when tested again.

TEST ENVIRONMENT
    Machine          : Tiger4
    Kernel           : 2.6.18.8-xen
    Changeset        : 19912:721c14d7f60b (xen-unstable)
                       913:b086278a4406   (linux-2.6.18-xen)
                       137:3ad73b4314e3   (efi-vfirmware)
                       b471f03            (qemu-xen-unstable)
    Dom0 OS          : RHEL4 U2 (2P)
    DomU OS          : RHEL4 U2 (8P, using tap:aio)
    DomVTi OS        : RHEL4 U2 (8P, with PV-on-HVM drivers)
