Hi Ian,

 

     Thank you for your relpy!

     Because upstream qemu does not support vhd backing file,  we have to use qemu-dm and xm for vm management.

     Maybe my configuration is not correct , or is there any way that can attach floppy disk with xm command?

Best Regards

I don't know about Xen 4.1 but for modern Xen with the xl toolstack then

you can pass arbitrary arguments to the device model using

device_model_args in your config file, which should enable you to pass

the necessary options.

 

I've no idea if xm supported the same thing or not, you could always use

a wrapper script around the dm I suppose.

 

Ian.
