Thanks, Todd:

Ultimately, I found the answer in Section 9.3 of the the SLES 11 Virtualization with Xen Administration Guide (i.e., setting the configuration options [correctly] in /etc/xen/xend-config.sxp resolved the problem).

I believe this has to deal with the exchange of SSH keys, or, configuring Xen to accept connections on specific ports.

As for configuring Xen, here's a good reference: http://www.virtuatopia.com/index.php/Migrating_Xen_domainU_Guests_Between_Host_Systems.

When I attempt to migrate a VM from one host to another (sles-xen-2 -> sles-xen-1) I get the error message:


> sles-xen-2:~ # xm migrate --live SLES-11-SP2-1 192.168.1.3
> Error: can't connect: [Errno 111] Connection refused ...

What might be the problem? FWIW: I've already verified that iptables rules have been cleared and that xend does not have any ports open on the recieving host:

> sles-xen-1:~ # ifconfig bond0
> bond0     Link encap:Ethernet  HWaddr 00:30:48:87:22:C8
>           inet addr:192.168.1.3  Bcast:192.168.1.255 
>Mask:255.255.255.0
>           ...

>           UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1

> sles-xen-1:~ # iptables -L
> Chain INPUT (policy ACCEPT)
