Hello ,
I have setup 2 Xen systems on the same subnet and was
attempting a regular migration.The domU image which I
am migrating is  based on the disk itself (file backed
VBD).
When i do an xm migrate ,it simply seems to hang (or
rather no activity is seen). 

So some questions:
What time does it normally take for migration?
Are there any pre-migration steps that I have missed?


Attached below is the log(xend.log)  snapshot.
Any help will be appreciated
Thanks,
Dakshina
