Subject: [Openstack] Live Migration with libvirtError

 

HI everyone,
when I test live migration use NFS ,that's my sitting according to
 
<http://docs.openstack.org/essex/openstack-compute/admin/content/configuring
-live-migrations.html>
http://docs.openstack.org/essex/openstack-compute/admin/content/configuring-
live-migrations.html

1.add this line /var/lib/nova/instances *(rw,sync,fsid=0,no_root_squash) in
/etc/exports
2.mount -t nfs 172.18.32.7:/var/lib/nova/instances /var/lib/nova/instances
at compute
and change some setting in libvirt.conf and libvird-bin.conf add a option -l
3.restart service

then I create instance in compute node ,find error
that's my nova-compute.log as follow:
2012-08-09 13:13:03 ERROR nova.manager [-] Error during
