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

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

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.
