Abhishek,
These article may be useful . - (http://blog.zhaw.ch/icclab/setting-up-live-migration-in-openstack-icehouse/) - (http://docs.openstack.org/admin-guide-cloud/content/section_configuring-compute-migrations.html) If you want to easily try to live-migration , I recommended you change migration-uri from ssh to tcp. So you may need to change the following configuration. - live_migration_uri ( in nova.conf ) from "qemu+ssh://hogehoge@%s/system” to “qemu+tcp://%s/system” - listen_tls (in /etc/libvirt/libvirtd.conf ) from “1” to “0” - listen_tcp ( in /etc/libvirt/libvritd.conf ) from “comment out” to “1” - tcp_port ( in /etc/libvirt/libvritd.conf ) from “comment out” to “16509” - auth_tcp ( in /etc/libvirt/libvritd.conf ) from “sasl” to “none” - libvirtd_opts ( in /etc/default/libvirt-bin ) from “-d” to “-d -l” I hope this information help you.
