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
though).
You can try this in two ways:
- if you are using xl, you can add the following line to the VM config
file:
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.
