icehouse block live migration failed

I am not able to successfully migrate (block live migration) an instance with Icehouse. My configuration is: 1 controller node 1 network node(neutron) 2 compute node 1 Netapp FAS storage connected via cinder ISCSI driver.

The instance runs on compute1/2 with disk volume on Netapp storage via iscsi. The compute node doesn't have any shared storage.

The instance boots fine, without any network or storage problem.

But when I execute "nova migrate --block-migrate c9528394-fc21-4723-a013-49bcc0dd7e88" to migrate an instance from compute1 to compute2, the migration fails with the following errors:

I've followed this guide http://docs.openstack.org/trunk/config-reference/content/section_configuring-compute-migrations.html and I have modified my configuration files as following: compute nova.conf:

[libvirt]
virt_type=kvm
live_migration_uri=qemu+tcp://%s/system
live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE

live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE

libvirtd.conf

listen_tls=0
listen_tcp=1
tls_port ="16514"
tcp_port ="16509"
auth_tcp = "none"

/etc/sysconfig/libvirtd

LIBVIRTD_ARGS="--listen"

Is there anyone who faced the same problem? kind regards
