 I can't get xen live migration to work - CentOS 5.6. I have set up
 xend-config.sxp as per RHEL5 virtualization guide, but when I try
 it, I get

[root at xenhost1 ]#  xm migrate testwww xenhost2 -l
Error: (104, 'Connection reset by peer')
Usage: xm migrate <Domain> <Host>

Migrate a domain to another machine.


-h, --help           Print this help.
-l, --live           Use live migration.
-p=portnum, --port=portnum
                     Use specified port for migration.
-r=MBIT, --resource=MBIT
                     Set level of resource usage for migration.

 Any ideas what to check? brctl, xend-config.sxp, lsof, are all in agreement
 with http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/chap-Virtualization-Xen_live_migration.html.
