Xen community - Nov 2008 - Problem with fullyvirtualized guest direct kernel boot

Hi All,

I am trying to use fullyvirtualized guest direct kernel boot, but all I see
is the following error:
Error: (2, ''Invalid kernel'', ''elf_init: not an ELF
binary\n'')

Kernel, initrd and root file system are extracted from working Fedora 9 disk
image without any additional tinkering. Guest Fedora is clean and was
installed from scratch. When I use this whole disk image with
fullyvirtualized guest BIOS boot with, everything works fine. I also tried
paravirtualized guest bootloader with another linux kernel and it also works
fine. Xen version is 3.2.1-rc1-pre. Host OS is Ubuntu Hardy.

Here is the cfg file for BIOS boot:
name = "xen_f9_hvm"
builder = "hvm"
memory = "512"
disk = [ ''tap:aio:/tmp/f9.img,hda,w'', ]
vif = [ ''type=ioemu, mac=00:16:3e:5a:af:2a, bridge=eth0'', ]
kernel = "/usr/lib/xen/boot/hvmloader"
device_model = ''/usr/lib/xen/bin/qemu-dm''
vnc=1
vncunused=1
vnclisten="0.0.0.0"
vncconsole=1
apic=1
acpi=1
vcpus=1
serial = "pty" # enable serial console
on_reboot   = ''restart''
on_crash    = ''restart''

Here is the cfg file for fullyvirtualized guest direct kernel boot:
name = "xen_f9_hvm"
builder = "hvm"
memory = "512"
kernel = ''/tmp/vmlinuz-2.6.25-14.fc9.i686''
ramdisk  = ''/tmp/initrd-2.6.25-14.fc9.i686.img''
root= ''/dev/hda2 ro''
disk = [ ''tap:aio:/tmp/f9_disassembled/swap,hda1,w'',
''tap:aio:/tmp/f9_disassembled/root.img,hda2,w'', ]
vif = [ ''type=ioemu, mac=00:16:3e:5a:af:2a, bridge=eth0'', ]
device_model = ''/usr/lib/xen/bin/qemu-dm''
vnc=1
vncunused=1
vnclisten="0.0.0.0"
vncconsole=1
apic=1
acpi=1
vcpus=1
serial = "pty" # enable serial console
on_reboot   = ''restart''
on_crash    = ''restart''

What do you think can be the cause of this issue?
