Xen 3.2 - 32bit domU on 64 dom0 hangs at boot

["Sébastien RICCIO" <sr@swisscenter.com>]

Hi,

While trying the xen-unstable tree, I have trouble starting 32bits domU
on a 64bit dom0
using the kernel supplied in xen-unstable tree.

It hangs when it is starting /sbin/init.

The same domU boots with a  32-bit 3.1 domU kernel on the 3.2 64bit dom0.

Any clues ?

Command to build the domU 32 bit kernel:

dom0# XEN_TARGET_ARCH=x86_32 XEN_TARGET_X86_PAE=y make
linux-2.6-xen-build -j5
dom0# XEN_TARGET_ARCH=x86_32 XEN_TARGET_X86_PAE=y make
linux-2.6-xen-install -j5
