Hi Claudio

Here is my PHP code

<?php

    echo ("Looking up test domain\n");

    $con = new Libvirt('qemu+tcp://192.168.168.11/system');
    $duri = 'qemu+tcp://192.168.168.14/system';

    $dom = $con->get_domain_by_name("ldap");
    if ($dom==false)
    {
       echo ("Domain not found\n");
       echo ("Libvirt last error: ".libvirt_get_last_error()."\n");
       exit;
    }
    echo ("Domain found\n");

    echo ("Migrating domain to $duri\n");
    $rv=libvirt_domain_migrate_to_uri($dom,$duri, VIR_MIGRATE_PEER2PEER | VIR_MIGRATE_UNSAFE | VIR_MIGRATE_OFFLINE | VIR_MIGRATE_PERSI
ST_DEST | VIR_MIGRATE_UNDEFINE_SOURCE);
    if ($rv==false)
    {
       echo ("Failure!");
       echo ("Libvirt last error: ".libvirt_get_last_error()."\n");
    }
    else
    {
       echo ("Success\n");
    }


Here is the error message when I tried to migrate (powered off) domain
----------------------------------------------------------------------
Looking up test domain
Domain found
Migrating domain to qemu+tcp://192.168.168.14/system
Failure!Libvirt last error: Requested operation is not valid: domain is not running


And here is the error message when I tried (powered on) domain
--------------------------------------------------------------
Looking up test domain
Domain found
Migrating domain to qemu+tcp://192.168.168.14/system
Failure!Libvirt last error: Unsafe migration: Migration may lead to data corruption if disks use cache != none


Here is the php_error_logs

[17-Oct-2013 05:17:42 America/New_York] PHP Notice:  Use of undefined constant VIR_MIGRATE_UNSAFE - assumed 'VIR_MIGRATE_UNSAFE' in /home/www/virtspace/inc/mig.php on line 21

According to above php_notices, both VIR_OFFLINE AND VIR_UNSAFE options are not available.

My libvirt version on kvm hosts is (1000002), and php-libvirt version is (0.4.8)

Could you tell us a bit more about your setup and show your code?
Which version of libvirt are you using?

My guess would be that you don't have shared storage and are using
the VIR_MIGRATE_NON_SHARED_DISK flag when migrating, which only works
if the domain is running.

In that case, you could start your domain in the 'paused' state,
migrate and then destroy it.
