Hi all~:
  I know we should use network storage to support live migrate,such as nfs,nbd.
  But same time we want to use the  vhd file with advanced features to be a disk.
  So, i first connect to a nbd server from A,and mount /dev/nbd0 to /mnt/nbd0,then
create a vhd file at /mnt/nbd0 to be used by vm. When i want to  migrate it to B,
i should get the vhd file by connect to the nbd server from B,and mount /dev/nbd0
to /mnt/nbd0 of B.Unfortunatly this way can't work.
  When i read the code about 'xm migrate', i find remote pc had create device before
pre-copy memory...
  Should you tell me how can i migrate  a vm used vhd lively ?Thx~~
