[Xen-ia64-devel] [Patch] booting Guest domains w/o initrd on RHEL4

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, all

This patch can boot DomU WITHOUT initrd as RHEL3
when we boot Xen + Domain0 using RHEL4.

Domain0 using RHEL4 must use initrd.
The following error is showed when we boot DomainU.
  RAMDISK: Couldn't find valid RAM disk image starting at 0.
This error is caused by "bp->initrd_start" used Domain0 value.
I fixed it's bug.
But this patch is temporal,
because I want to make a part of initrd in libxc and so on.
Please wait. ;)
