Hi everyone<br>i&#39;ve been trying to migrate a domain from hostA to 
hostB.But everytime i did it with <br>&quot;virsh --live migrate 
&lt;Domain&gt; xen+ssh://root@Destination&quot;,<br>it failed and told me 
something like <br>&quot;Error Domain not 
found:xenUnifiedDomainLookupByName&quot;.<br>The same thing happened when i 
tried to do the same thing with libvirt API like virDomainMigrate &amp; 
virDomainMigrateToURI.<br>i am confused about this.<br>So can anybody 
can tell me why?Thanks a lot.<br>BTW,the OS is CentOS 5.4 with libvirt 0.7.7 and Xen 3.4.0.<br>
