Hi
I have setup xen3.0.2.on two nodes,
I try to migrate a vm from one to the other ,
I have modified xend-config.sxp ,by uncommenting (xend-relocation-server
yes) and (xend-relocation-port 8002)
I put the vm conf file and img file in a nfs node which the two xen node
can get access to
but it does not work with the error as follows
Error: (104, ''Connection reset by peer'')
Xend.log in the sender node :
[2006-09-13 09:17:43 xend] ERROR (xmlrpclib2:124) (104, ''Connection
reset by
peer'')
Traceback (most recent call last):

sock.recv(80)
error: (104, ''Connection reset by peer'')
xend.log in the receiver node:

10.10.107.1:57983 (10.10.107.1) for port 8002.
Could anyone help me ?
Thanks in advance

By default a relocation server will only accept VMs from localhost. You probably need to expand this to include your remote host. Sorry, I can''t specify the exact parameter - I don''t have access to my XEN server at the moment.

Thank you for your reply connection was rejected, the sender can ping ,ssh the receiver , but when it comes to migrate ,connection was rejected ,how can I connect it to migrate vm successfully? , -----邮件原件----- 发件人: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] 代表 Tom Z.

What do you mean "img file" ? To boot a vm ,xen need a conf file and a img file , img file is that. Yesterday ,you give me a reply and a suggestion ,but it does not work This:> > error: (104, ''Connection reset by peer'') >and this:> xend.log in the receiver node: > > [2006-09-13 09:19:58 xend] WARNING (tcp:73) Rejected connection from > 10.10.107.1:57983 (10.10.107.1) for port 8002. >together means that.

By default this is set to ^localhost which should be changed to allow other hosts.
