Xen users - Jul 2007 - HVM Linux just installed but does not do its first boot

Just successfully installed SLES9.3-32bit as file-backended HVM domU.

Everything went OK, the distributive partitioned its "harddisk" into
root and swap OK, have its grub installed into sda boot sector, but I could not
make to boot no one single first time after installation. Every domU boot gives
the following screen for a short time and dies:



Booting from Hard Disk...

Boot from Hard Disk failed: could not read the boot disk

FATAL: No bootable device.



I beleive this it QEMU output, is not it?

So when I place a Knopix (bootable linux) CD image into domUs cdrom, my domU
does recognise the /dev/sda disk just fine: I could run even fdisk, fsck, and
mount.



here is the domU config file I used:



--------------------------------------------

import os, re

arch = os.uname()[4]

if re.search(''64'', arch):

    arch_libdir = ''lib64''

else:

    arch_libdir = ''lib''



kernel = "/usr/lib/xen/boot/hvmloader"

builder=''hvm''

memory = 512

vcpus=2

name = "sles9.3-32bit"

vif = [ ''type=ioemu, mac=aa:a0:01:ad:a0:a0, bridge=xenbr0'' ]

disk=[''file:/IMG/sles9.3-32bit.disk,sda,w'']

#disk=[''file:/IMG/sles9.3-32bit.disk,sda,w'',''file:/ISO/Knoppix-5.0.1.iso,hdc:cdrom,r'']

device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''

#boot="d"

sdl=1

vnc=0

vncunused=1

vncconsole=0

stdvga=0

--------------------------------------------



I am not a novice in Linux and do not suspect I made a mistake installing it for
some 1000th time. So why disk not recognised by XEN? Could not find an answer so
far.



Environment: XEN3.1, dom0 runs SLES9.3-64bit, SUN X4600 server.

Why are you using SLES 9.3? Can you trivially update to 10.x?

Hi,

If I remember correctly, booting from scsi disks is not yet supported
for HVM domains. Try using ''hda'' instead of
''sda''.
