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.

Hi,
I have done a multinode kilo installation with a controller, a network node
and two compute nodes.
I am able to boot instances on both the compute nodes and they are going in
to ACTIVE state.
When I am trying to migrate instance from one compute host to the other I am
facing an error :
[instance: 6cf0c4e2-fc9d-4db5-aeea-314271ea119f] Setting instance back to
ACTIVE after: Instance rollback performed due to: Resize error: not able to
execute ssh command: Unexpected error while running command.
Command: ssh 10.0.0.32 mkdir -p
/var/lib/nova/instances/6cf0c4e2-fc9d-4db5-aeea-314271ea119f
Exit code: 255
Stdout: u''
Stderr: u'ssh: connect to host 10.0.0.32 port 22: Connection refused\r\n'
So how can we configure migrations in a multinode setup ? Why am I getting an
SSH error ?
Please provide me some information regarding this.
I configured passwordless authentication between the nodes thinking it is an
SSH probelm but the error remains.
Regards
Abhishek Talwar
