I have a multinode OpenStack kilo setup with 2 compute nodes, a controller and a network node. I am trying to migrate a Vm from host to the other, but there is a migration failure and the VM stays on the same host.

I can ping between the compute nodes, and I have set libvirt to listen mode. Using the following steps:

  1. Modify /etc/libvirt/libvirtd.conf. before : #listen_tls = 0 after : listen_tls = 0

before : #listen_tcp = 1 after : listen_tcp = 1

add: auth_tcp = "none"

  1. Modify /etc/init/libvirt-bin.conf. before : exec /usr/sbin/libvirtd -d after : exec /usr/sbin/libvirtd -d -l -l is short for –listen

  2. Modify /etc/default/libvirt-bin. before :libvirtd_opts=" -d" after :libvirtd_opts=" -d -l"

  3. Restart libvirt. After executing the command, ensure that libvirt is successfully restarted. $ stop libvirt-bin && start libvirt-bin $ ps -ef | grep libvirt
