Re: [libvirt] Migration issue php-libvirt
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);
}

You don't mention what hypervisor you're using. IIRC only the QEMU

supports the VIR_MIGRATE_OFFLINE flag.

Re: [libvirt] Migration issue php-libvirt
Hi,
the interesting thing is that you use constructor as
$conn = new Libvirt('connection-uri');
You should be using libvirt_connect() API instead. See [1] for example.
Not all of the defines are defined in the libvirt-php scope, that is
correct and patches are welcome :-)
Thanks,
Michal
