   using following steps we can add secondary hard disk in xen vm:

   1. first create a new block device file:

       dd if=/dev/zero of=/path/to/diskfile.dsk bs=1024k count=50000

   this will create a +50GB file

   2. add above created file as harddisk:

   para-virtualized:

   xm block-attach 6 /vmfs/test1disk2.dsk /dev/xvdb w

   for full-virtualized:

   xm block-attach 6 file:/vmfs/test1disk2.dsk xvdb w

    

   that's it. a new block device file /dev/xvdb will be created in guest domain(Dom id 6).
