[Xen-users] Migration problem in xen


i have loaded the virtual machine using Virt- Manager. i installed xen on 2 hosts which are connected via LAN now i am trying to migrate the VM from one host to another host. i configured xend.config.sxp accordingly for migration. Both hypervisors are remotely connected to each other successfully. when i do the migration it shows the error: 

Unable to migrate guest: Domain not found: xenUnifiedDomainLookupByName
Unable to migrate guest: Domain not found: xenUnifiedDomainLookupByName

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/migrate.py", line 553, in _async_migrate
    vm.migrate(dstconn, migrate_uri, rate, live, secure, meter=meter)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1163, in migrate
    self._backend.migrate(destconn.vmm, flags, newname, interface, rate)
  File "/usr/lib/python2.7/site-packages/libvirt.py", line 822, in migrate
    if ret is None:raise libvirtError('virDomainMigrate() failed', dom=self)
libvirtError: Domain not found: xenUnifiedDomainLookupByName

i didn't use any shared storage like NFS. If u faced such a problem then please suggest me solutions.

IS it required to use shared storage for migration?

if u used xen-tools to create VM. then please send me the configuration file(.cfg) with required changes in it . i actually used one but its not working..

regards and thanks
