Xen users - Apr 2006 - migrating domU from one dom0 to another dom0 error

Hi all,

I tried to migrate a domain from 1 server to the other one. This is what 
I did...

clever2:/var/log# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      512     4 r-----    95.7
clever2vm01                        3      128     1 -b----    10.1


clever2:/var/log# xm migrate  clever2vm01 10.0.0.36
Error: Received invalid response from Xend, twice.
clever2:/var/log#

clever2:/var/log# xm migrate 3 10.0.0.36
Error: Received invalid response from Xend, twice.
clever2:/var/log#


I got the invalid response message. Can anyone point me in a right 
direction to make things work?

Heres my machine config :

debian sarge

xen 3.01, 2.6.12.6-xen0

Running LVMs on top of raid 1 for my xen domains.

Can anyone point me in the right direction please?

Here are the logs from my xend-dedug.log...

error: (104, ''Connection reset by peer'')

as far as I know u need the partition of domU connected to it via some kind of 
network protocol like nfs or nbd u can''t migrate a machine that has
it''s
partition in an lvm volume on the machine itself (at least not directly 
connected (u can always put nfs on domain0 and connect domU to nfs dom0))
maybe I misunderstood your problem

If you don''t have network storage of some kind, you will need to shut
the
domU down, migrate the domU''s disk image by hand (dd?), copy the config
file over, and boot it up on the new dom0.
