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~~
