libvirt users - Nov 2013 - Migration function is not supported by the connection driver: virDomainMigrate2

Greetings;

I'm running Fedora 19, Xen 4.2.3, libvirt 1.0.5.6.  I have two identical
servers x1 & x2.  I've read http://libvirt.org/migration.html &
I've
created certificates for tls according to
http://wiki.libvirt.org/page/TLSSetup

I can do this on both servers, and from a third admin server:

# virsh -c xen+tls://x1.localdomain hostname
x1.localdomain

and...

# virsh -c xen+tls://x2.localdomain hostname
x2.localdomain

It appears I can connect without issues.

No matter what I try, I cannot get migration to work  :-( x 1000!  I've
created a test DomU named "z19", which uses a DRBD block device
between the
two hosts.  It's running on x1, (and obviously not on x2), and I want to
migrate it to x2.

When I attempt to migrate I get the following.  (Although, I've tried every
permutation of syntax I've read about.  The following appears to be most
reasonable for my situation?)

# virsh migrate --live z19 xen+tls://x2.localdomain
error: this function is not supported by the connection driver:
virDomainMigrate2

# virsh -c xen+tls://x1.localdomain migrate z19 xen+tls://x2.localdomain
error: this function is not supported by the connection driver:
virDomainMigrate2

# virsh migrate --live z19 xen+ssh://root@x2.localdomain
error: this function is not supported by the connection driver:
virDomainMigrate2

I've set libvirtd.conf:
  log_level=1

Which reports nothing.

There is a great amount of conflicting information on this topic.  It's
difficult to ascertain which to listen to.  Any suggestions you could give
me would be greatly appreciated.

What does 'virsh version' report ?  I'm guessing that it is going to
say 'xenlight' as the virt driver and I'm afraid that does not yet
support migration.  Only the legacy XenD driver supports migration
with Xen.
