Unfortunately qemu-xen doesn't understand this option from xenstore so
it cannot be done from the VM config file.

However if you manually add "-fda /root/floopy.img" to the qemu command
line options, it might just work (I haven't tried this so I am not sure
You can try this in two ways:

- if you are using xl, you can add the following line to the VM config

device_model_args = ['-fda', '/root/floopy.img']

this would cause '-fda' and '/root/floopy.img' to be added to the qemu
command line.

- modify the VM config file to point to a wrapper script
for the device model:

device_model_override = '/path/to/wrapper_script'

the wrapper script is just a bash script that executes qemu adding '-fda
/root/floopy.img' to the command line arguments.
