[Xen-users] Xen 3.0.4 and booting from floppy images

["M.J. Rutter" <mjr19@xxxxxxxxxxxxx>]

I am currently having problems persuading 3.0.4 (binary dist) to boot a 
virtual machine from a virtual floppy when running in HVM mode. Although I 
can boot a real computer from a real drive with my floppy image, with Xen 
it merely hangs after saying:

HVMAssist BIOS, 1 cpu, $Revision: 1.138 $ $Date: 2005/05/07 15:55:26 $

If I give it a completely blank floppy image, it does the same (I'd
expect a "not bootable" complaint), and if I point it at a floppy
image which does not exist, it produces no window at all, and is shown
in state '------' by "xm list", as, indeed, are the other two.

What am I doing wrong? My minimalist configuration file reads:

kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
device_model = '/usr/lib64/xen/bin/qemu-dm'

memory = 256
name = "floppy"
fda="/scratch/VM/FDSTD.144"
sdl=1
boot='a'

and "xm info | grep xen"

release                : 2.6.16.33-xen
xen_major              : 3
xen_minor              : 0
xen_extra              : .4-1
xen_caps               : xen-3.0-x86_64 hvm-3.0-x86_32 hvm-3.0-x86_32p 
hvm-3.0-x86_64
xen_pagesize           : 4096
xen_changeset          : Mon Jan 08 14:09:25 2007 +0000 13130:4d34be661f31
xend_config_format     : 3


The thing boots from hard disk images fine, happily running a 32 bit
version of Suse 9.3, and FDSTD.144 is a FreeDOS bootable disk. The
machine itself is running SLES 10.0 on a Core2, with the 2.6.16.33-xen
kernel.

With thanks for any advice,

Michael
